Introduction
Grameenphone arranges much training every year in local and overseas .They decided to develop a computer base Training Accounts Information System. Because the prevailing management information system is very time consuming due to its manual operational system. Adequate error can take place by using manual system. The name of the project is Training Accounts Information System (TAIS) of Grameenphone Ltd. The system is designed to replace all manual record and delivery automated information system of trainings thereby enhancing the efficiency of trainings management. By this system they can manage their training and as well as the business control unit.
1.1 Origin of the Report
Independent University, Bangladesh offers a 6 credits course as Internship for the graduating students in her course curriculum. The curriculum requires every student to do an internship in a reputed organization for hands on experience about the professional works. It is a practical exposure of theoretically gained knowledge and can be considered as a preliminary trial to be acquainted with any organization and to make oneself confident enough to enter into service life and start building career. As the outside world is very much competitive for anyone after graduation, IUB provides such an opportunity to build up the capability with most appropriate opportunities. This gives the student great opportunity in the service world and also to get exposure to various diversifications of the service world. Intern students are supervised under a particular faculty member throughout their Internship stage. Here the student gets the chance to apply his theoretical knowledge and practical skill that he has gained in the entire under graduation student life. They are responsible to report weekly or fortnightly to his/her respective Supervisor to get his/her assistance. And the project gets advancement by following the Supervisor’s instruction. The internship period is for at least 3 months. After that the student submits a report on his project work, which reflects his knowledge gained in the entire B. Sc. course. That is the main purpose of this report to give an outline of the outcome of internship during the entire period of the course in the company.
1.2 Purpose of Internship
In our study period mainly we gain theoretical knowledge but now a day, in the job market is no substitute for principle work experience. Getting meaningful work experience in one’s major field of study or career interest should be a number one priority a vital par of college education. Today students with career related work job experience is
getting the best interviews and job offers. The major targets to offer Internship in IUB are as following:
1. This is the beginning of a student’s professional career.
2. The student’s competency and efficiency in the working environment can be assessed from this course.
3. Teaches the student to take up the responsibility and pressure of work.
4. Teaches the student to learn from work.
5. To help students enhance their creativity and efficiency in dealing with projects related to their field of study.
6. To evaluate the person’s ability to communicate and under pressure, if required.
7. Helping students to express dependability, initiative, resource fullness and professionalism in the tasks they are assigned.
8. To increase the confidence level of IUB students, which would help them work after graduation.
1.3 Internship policy
Since internship has been designed to apply classroom knowledge in the workplace, it is suggested to do internship after completing at least 105 credits hours of course work. Students have to submit a proposal about the work he/she is doing in the internship and the name of the chosen organization to the respective school. The students have to submit progress report to the academic supervisor after certain interval. The whole work will ends up with completing three months of full time office work, submitting final report and having the oral exam.
1.4 Objective of my project
Easier Access: User can easily access the data related to the production and delivery.
Save time: It can save time because they can easily find the data they needed.
Automation of existing system: Using this software they can reduce their paper-based work and automatically update their information.
Less Documentation: It reduce paper based work that’s why it reduce Documentation.
Faster working performance: Data can be processed faster they the existing system.
Update Information automatically: It can update information automatically.
Availability of updated information: All the information is available in the system.
1.5 Scope of the project
• To design the Training Accounts Information System in such a way so that the users can view all the important data at a glance.
• To design the system in such a way that less documentation is needed.
• To schedule the project efficiently so that the administration can provides the records easily.
• To ensure the reliability of the system so that incase of H/W and/or S/W failure, actions can be taken. So necessary software backup should be kept safely.
• To design the system such that in future it can be updated easily.
• To design the system is user friendly and to provide a faster performance.
1.6 Preliminary Constrains
Having no consistent Training Accounts System using several software in different platform, which is yielding inefficiency in working process. Data inconsistency and misleading information are frequent phenomena in Training Accounts system. As they has to input same information thrice in three software it is killing much of their time which they could utilize for other development work of Training Accounts. As none of the software is generating any efficient report it is creating problem to the management level to take any strategic decision.
1.7 Limitation
Three months Internship program was not enough for me to thoroughly study and analyze the entire system. I had to observe and learn installation of SQL server within the sort span of time. I faced various problems to learn visual C++ and Crystal report. It was very
short time to go through all of this and implement it properly. But I tried my best to make the system fully functional.
1.8 Time Line of the Project
Project Management scheduling is one of the most essential factors. By scheduling, we distribute the given time for the different phases of the project. It gives the project a pace and defines the deliverables of the different phases. Following is the expected and actual work schedule.

ORGANIZATION SYNOPSIS
2.1 Company Profile
Grameenphone is one of the largest private sector investments in the country with an accumulated investment of BDT 5200 crore up to December 2005. Grameenphone is also one the largest taxpayers in the country, having contributed nearly BDT 5000 crore in direct and indirect taxes to the Government Exchequer over the years. Of this amount, BDT 1670 crore was paid in 2005 alone.
GP was also the first operator to introduce the pre-paid service in September 1999. It established the first 24-hour Call Center, introduced value-added services such as VMS, SMS, fax and data transmission services, international roaming service,WAP, SMS-based push-pull services, EDGE, personal ring back tone and many other products and services.
Grameenphone nearly doubled its subscriber base during the initial years while the growth was much faster during the later years. It ended the inaugural year with 18,000 customers, 30,000 by the end of 1998, 60,000 in 1999, 193,000 in 2000, 471,000 in 2001, 775,000 in 2002, 1.16 million in 2003, 2.4 million in 2004 and it ended 2005 with 5.5 million customers.

CHAPTER THREE
OBJECTIVE AND METHODOLOGY
3.1 System Development Methodology
In general, methodology is a systematic description of the sequence of activities required to solve a problem. In context to system development, methodology is a collection of procedures, techniques, tools and documentation aids, which help the system developers in their efforts to implement a new system. A system development methodology must provide means to:
• Ensure that a consistent approach is applied to all project
• Establish the system within a time limit and an acceptable cost
• Reduce the risks associated with short-cuts
• Records accurately the requirements for a system
• Monitor the progress of system development
• Produce consistent and complete documentation
• Indicate any changes which need to be made as early as possible
• Maintain continuity of the project so that previous projects are easily
• Understood by the new workers.
3.2 Overview of System Development Phases
The process of putting system into place and continuing and enhance them refer to system development. System development process can divide into different phases and activities. No matter what the phases are, the development project is some combination of problem, opportunity and directives.
3.2.1 Preliminary Investigation
The perceived problems is defined training accounts system that triggered the projects and to assess the risk of pursuing the project. Also to figure out the scope of the project, preliminary requirements, constraints, project participants and schedule to establish the project charter. Few identified requirements of the “Training Accounts Information System” project that are given below:
The systems will response when end users need to add, modify or delete trainee information.
The systems will response when the status of the training and travel form has to be changed.
The systems will response when training and travel information has to the
recorded.
3.2.1.1 Time line of the Project
Project Management scheduling is one of the most essential factors. By scheduling, we distribute the given time for the different phases of the project. It gives the project a pace and defines the deliverables of the different phases. Following is the expected and actual work schedule.

Fig 3.2: Project Work Schedule
3.2.2 System Analysis
System Analysis is studying business systems to learn current methods and assess effectiveness. This phase itself consists of component phases:
• Problem Analysis (analyzing the current system)
• Requirement Analysis
• Decision Analysis
• Feasibility Study
(a)Problem Analysis is the study of the existing training system. At first the problem analysis is carried out to analyze the existing training in Grameenphone. The flaws and shortcomings of the current system were identified.
(b)Requirement Analysis was conducted to identify the organization’s information, the requirement specifications for the new system.
(c)Decision Analysis identifies solutions, analyze their feasibility and recommend a new system.
(d)Feasibility Study was carried out to ascertain that the new project is viable and will be accepted in the organization. Three major areas of feasibility study are:
1. Technical Feasibility
2. Economical Feasibility
3. Operational Feasibility
3.2.3 System Design
While system analysis describes what a system should do to meet information design of an information system requirement. System design shows how the system will fulfill these objectives. The design of information is the overall plan or model for that system.
(a) Process Modeling
Approach concentrated on the identification and understanding of the training and training record keeping processes. So it required dedicated time on the proper Process Modeling since its processes defines any system. Try to employed extensive use of the following graphical tools:
1. Data flow diagram
The Gane & Sarson approach is used to draw DFDs and designed the system.
2. Entity Relationship Diagrams (ERD)
The Entity Relationship (ERD) model database design identifies the Entities (Tables), their attributes, and their inter-relationship. Both logical and physical diagram are available.
3. Data Dictionary
The detailed data dictionary for the database is identified. All the different data to be stored in each of the database tables.
3.2.4 Testing
Exhaustive and through testing must be conducted to as certain whether the Training Accounts Information System produces right result. Testing of information system can be
broken down into three types of activities:
I. Unit Testing
II. System Testing
III. Acceptance Testing
3.3 Fact Finding Technique
The following are the fact-finding techniques that were used to determine the requirements of a system: Interview, Questionnaire, Record Review, and Observation.
3.3.1 Interview
Ms. Ishrat Jahan (Manager, Training) of Grameenphone were Interviewed to collect all
the information related to training. Also Interviewed Mr. Rajib Alam Chowdhury (Officer, Training) for further and internal information.
3.3.2 Questionnaire
Most of the information is collect by interviewing, record review and observation; as a result of that questionnaire wasn’t done here.
3.3.3 Record or Document Review
All the existing sample records about the admission system were checked very vigilantly. Like Trainee information form, application status, the report of number of trainee were appear for training in a particular quarter.
3.3.4 Observation
All the different steps that are performed sequentially in the system were very seriously observed. With the help of training team personnel; it was easy to find out problem and overhead works occurring in the system.
3.4 Software Application Aids Used
A number of Software aids will be used to facilitate the design and development phases. For the graphical design approach, CASE (Computer Aided System Engineering) tool namely Microsoft Visio will be used. Using this powerful software, the DFDs, and ERDs are drawn.
3.5 Physical Development
Every attempt was made to emphasize User-friendliness. Wherever possible options were put in place to reduce or facilitate user input (e.g. Drop-down-lists, Comboboxes, Radio buttons etc.) the unit test is done. A user-friendly menu will also develop with Visual Basic (VB). In the coding phase, proper programming practices will follow in the development of the SQL server 2000 trigger code. Whenever compilation errors will encounter, extensive debugging will do to remove them.
CHAPTER FOUR
SYSTEM ANALYSIS
4.1 Problem Analysis
In problem analysis the main key concern was to study the existing system, try to collect the factual information from system users, find out the existing problems etc. Here also core apprehension was to come across problem solutions and try to think and search the system improvement techniques.
4.1.1 Existing System
One of the major goals of system analysis is to study an existing system, its working environment, evaluate its effectiveness to meet the organization’s requirements. In order to analyze the existing system it is significant to learn current methods and assess effectiveness. The problems in the existing system are analyzed and the requirements of the system are defined.
Training Manager’s Office:
The core intention of Training Manager’s Office is store all the training applicant information in such a way that whenever any information is required they can use it. Like applicant information form, status, the report of number of applicant was appearing for training in a particular quarter.
How admission office help applicants
At first Training Manager’s Office do the counseling, means helping applicant-providing
applicant required information.
• Help applicant to fill the training and travel form.
• Inform the application status
• They also inform the visa date those who passed the preliminary steps.
4.1.2 Problem in Existing System
Maintaining paper files to keep the interested training applicants information all together and prepare the approved applicants list . Then they select the applicants to for training. As a separate form is maintained for each trainee, whenever any necessary action takes place, they have to find it out the required form and also the record is kept in the personal file of the trainee. Due to the manual maintenance error occur during information processing. Whenever any report is needed, all the personal files have to be searched which is absolutely waste of valuable time. Again because of the lack of time none of the records has any backup copies so if any useful paper is lost then they have to face a terrible situation. Then data can’t be retrieved as information. That’s why all the training unit of Grameenphone needs to develop a new reliable process.
4.2 Requirement Analysis
In the software industry, catastrophic software failures are common. If the software is based on inaccurate requirements, then despite well-written code and design, the software will be unsatisfactory. Therefore a System’s Requirement Analysis is an important component of the system development process. The specific findings which my requirement analysis of the system yielded are listed below:
4.2.1 Purpose of the Training
In education, certification, counseling, and many other fields, training is a tool
or technique intended to bring up of knowledge, skills and/or abilities. The core purpose of training is to develop the employee competence level.
4.2.2 Functional Requirements
What steps are performed (input, process, and output)?
For training management perform the following steps. These are listed below:
Step 1: Training applicants search common folder and collects the training and travel form.
Step 2: Filling the training and travel form applicants put forward the form to training office.
Step 3: Submitted forms are tartan that all the forms fills up perfectly.
Step 4: Data entry person enter the applicant’s information into the system.
Step 5: If applicants number is more than capacity then applicants list are sorted
according to supervisors need.
Step 6: Request mail from trainee/manager to training section
Step 7: Travel & Training form raised by the trainee after the approval from supervisor, and department head
Step 8: Received Travel & Training form by training section
Step 9: Approval from training manager
Step 10: Approval from Cost control
Step 11: Approval from CTO
Step 12: A1 send to the vendor for the final confirmation of the training seat
Step 13: Travel and Training form forwarded to Finance by Cost control
Step 14: Approval and budgetary conformation from Finance budget unit and CFO
Step 15: Approval from Director HR
Step 16: Approval from MD
Step 17: Approval from HRD
Step 18: Received Invitation Letter from vendor
Step 19: Visa processing starts from Travel desk (HR)
Step 20: Ticket confirmation from Travel Desk (HR)
4.2.3 Nonfunctional Requirements
• Where are they performed?
The most of the steps are performed in training office. In this process different
unit, accounts department and higher administration of the company also involve.
• Who performed them?
Manager: For sending trainee there is a manager to brief up the detail to
Applicants and his/her managers and looking up the eligibility and status of the
applicants.
Officer: They enter relevant data into the system. Also they generate required reports for management. They help manager to manage the training
• How often it is done?
The process of sending employee for training is a continuous process.
• How great is the volume of transaction?
The volume of transaction is not fixed, it fluctuates. It depends on the number of
applicants employee. However, all the information is responsive, so the information is
very care fully handled.
• Who uses the resulting information?
Management needs the resulting information for analyzing and taking decision.
4.3 Constraints
Does a problem exist and what is the cause?
i) Problem
It is mentioned earlier that the system is paper based. For this reason
All the processes are time consuming
Processes are not effective in rush hour as they are using few books for
different transactions.
Errors are occurring most of the time.
Sometimes there are data redundancy problems.
If useful and important paper gets lost then they do not have any kind of
backup system for data recovery. So it lacks data security.
Information searching is very much time consuming.
Last but not the least it makes work tiring.
Solution
The new system will be automated and there will be simultaneous multiple user login
facility to keep records of the various transactions. This new system will reduce the
redundancy of data. Data backup mechanism will be introduced in the automated
system. Searching option will be given that will save valuable time. Users will find
interest by using the automated system.
ii) Problem
Top management need different kinds of report like how many applicants get the training for a particular quarter. They also have to compare different information. These require customized reports. With this existing paper based system it takes long time to deliver requested reports to management.
Solution
But the new system will offer customized report generation facility that will reduce work pressure and will save valuable time.
4.4 Feasibility Study
4.4.1 Technical Feasibility
The solution has the full technical feasibility, because our solution can be implemented with the available hardware, software and technical resources that are present at training unit. I will use SQL Server as backend and Visual Basic at front-end which is very friendly to the users. The new proposed Training Accounts Information System will be operating on the following
hardware:
¤ Machines consists of: Pentium IV 1.8 Processor, 40GB Hard drive, Mother Board
Intel, Sound Card, AGP card, Network Interface Card, 15 inch Monitor, Standard
Keyboard, Mouse and Printer.
¤ Server machine are UNIX based Sun Solaris Server machines. Reason behind to use this hardware
• All the accessories are available in the market.
• Easy to set up.
• Work will be Faster.
4.4.2 Operational Feasibility:
When an organization develops its new system, it involves additional cost. Implementing system will not require much training of the personnel. So it saves both time and money. The staff of those departments may feel uncomfortable while using the system and it will take some time before they start working efficiently using the system. This might cause the company to incur economic losses. On the other hand, as soon as the employees get acquainted with the new system, the company will start getting benefit from the system Company’s daily activities will be done more efficiently and the company will get economic benefits from it. This may be considered as an outcome of an investment. The following benefits will be provided by my new system:
(a) It will save time for organizational activities.
(b) It will make the employee more flexible.
(c) It will eliminate errors in organizational processes.
(d) It will avoid complication and to makes work more comfortable.
4.4.3 Economical Feasibility
The system will change the working environment rapidly. Once the system is implemented, there will be no more sluggish activities and erroneous movements from any staff. Since, the new system is designed according to the specification of the management and end users there will be no problem for the users of the system to operate on the system. The system is also designed to overcome the existing barriers of the organization. Moreover, the use of this system will not have any effect in organization’s culture, task, politics and standard operating procedures. The input and output screen of the system are designed to give a better GUI for the users. The system is also easy to operate and necessary tips/instructions will be given to the user during validation, verification and errors. The new system will make the problem solving activities more reliable, error free, efficient, flexible and acceptable to the overall end users. As less time and personnel is required means less expenses and better profit.
4.5 Feasibility Study Analysis
Therefore, after careful consideration of all the feasibility factors affecting the system
development project, it can be stated that the project is feasible for Grameenphone.
CHAPTER FIVE
SYSTEM DESIGN
System Design refers to the reconstructing of the components and the functions identified during the System Analysis phase to produce the backbone of the software product. The goal of the system design phase is
• Determining which system components will cover which requirements in the system specification, and
• How these system components will work together.
The design phase is concerned with technology-based views of the system’s Data, Process and Interfaces. The system is designed with the aim of fulfilling the requirements identified in the System Analysis phase. For this project both two designs- Logical Design and Physical Design are applied.
5.1 Data Flow Diagram (DFD)
A data flow diagram (DFD) is graphic representation of the “flow” of data through business functions or processes. More generally, a data flow diagram is used for the visualization of data processing. It illustrates the processes, data stores, and external entities, data flows in a business or other system and the relationships between these things.
5.1.1 Context Level DFD
The highest level of DFD becomes the Context Diagram. This puts the system to be analyzed into context by showing the external people, processes and systems with which the system as a whole interacts. This is similar to the Unified Modeling Language action diagrams.The context level diagram of Training Accounts Information System is shown here. In this diagram the basic work process of the software is shown. From this diagram it is identified that how in the system applicants collect admission form, submit it, how applicants are chosen after written test, viva-voice and then reports with all information are send to the management. The over view of the Training Accounts Information System are shown here as at a glance

Each process is numbered with an integer, generally starting from the upper left-hand corner of the diagram and working toward the lower right-hand corner. The major data stores and all external entities are included on system diagram. From the system level diagram of Training Accounts Information System can be divided, identify total five subsystems. These subsystems or process describes the feathers of each part of the total system in small segments and each segment describes the individual part of the program. The subsystems we have in the Training Accounts Information System of Grameenphone are as bellow:
• Application Process
• Selection Process
• Budget Process
• Application Progress Process
• Feedback Process

Essentially a database system is a computerized record-keeping system. It is regarded as a kind of electronic filing cabinet i.e., it is repository or container for a collection of computerized data files. Entity-Relationship Model (E-R Model) is a very functional tool for modeling the entities and their relationship in real world entities. So, the help of ERD model is being taken for the data requirements of Training Accounts Information System.

CHAPTER SIX
TESTING
In this chapter the discussion is about the software testing part. Testing is the process of exercising a program with the specific intent of finding errors prior to delivery to the end user. It tells about the performance of the system. It is also very important feature of any data entry system. Testing is done to find the errors or any kind of invalid input. So it also involves evaluating the result.
6.1 Steps Performed for Testing
• The testing has been performed by the following steps:
• Application’s higher-risk aspects have been identified, priorities are set, and
scope and limitations of tests are determined.
• Test approaches and methods – unit, integration, functional, system, load, usability tests, etc. have been determined
• Test environment requirements (hardware, software, communications, etc.)
are determined Requirements, functional design, and internal design specifications and other necessary documents have been obtained.
• Project-related personnel and their responsibilities, reporting requirements, required standards and processes have been determined.
• Input test data domain have been identified
• Tasks and required person-hour have been defined.
• Schedule estimates, timelines, milestones have been set
• Test plan document is defined and needed reviews/approvals are achieved
• Specific Test cases are written
• Reviews/inspections/approvals of test cases are achieved
• Tests are conducted according to specification
• Evaluation is done and reports are submitted.
• Un handled errors and bugs are recoded and notification is sent to project manager
• The testing cycle went on until final approve came from software manager.
6.2 Testing Classification
Testing of Information System can be broken down into three types of activities. These are Unit testing, System testing and Acceptance testing. In this project Unit testing and System testing were done.
6.2.1 Unit testing
Unit testing is the most ‘micro’ scale of testing; to test particular functions or code modules, typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. Not always easily done unless the application has a well-designed architecture with tight code; may require developing test driver modules or test harnesses. In unit testing each program are separately tested. It focuses on the modules to locate errors. If any error found, the module is revised and possible cause of error is defined and corrected. The thing that is considered to do the unit testing are narrated below-
• The forms are tested to ensure that information flows into and out properly.
• Data are examined to ensure that data stored temporarily maintains its integrity during all steps in an algorithm’s execution.
• All independent paths (basis paths) through the control structure are exercised to ensure that all statements in a form executed at least once.
• Boundary conditions are tested to ensure that the forms operate properly at boundaries established to limit or restrict processing.
Finally all error handling paths are tested.
• Testing was done with wrong password; mandatory fields are filled up
or not and also invalid inputs.
6.2.2 System Testing
System testing tests the functioning of the system as a whole in order to determine if discrete modules will function together as planned. It means integration of the modules and test whether they performed properly. All the modules and forms were tested to see whether they working perfectly or not. Also all the modules, forms and buttons were tested to integrate perfectly.
• The beneath is the training form and information is available.
• Whenever the “Save” button is clicked then information is saved.
6.2.3 Acceptance testing
Acceptance testing means the final certification that the system is ready to be used in production setting. It is not done yet because this software is only for one part of the total business process. After completing and integrating all the modules, the entire software will be installed in all the machines and then the users will test to find out the lacking of the computerized system. In testing part tester must input data as an end user. Also the software must give some kind of warnings or error messages to warn or instruct the end users.
CHAPTER SEVEN
CONCLUSION
7.1 Limitation
Training Accounts Information System (TAIS) was chosen from Grameenphone to accomplish internship project. While doing this project a lot of moral as well as physical support from the supervisor and employees of training unit of Grameenphone. The system has been developed using SQL server as the backend and the front-end User Interface was developed using Microsoft Visual Basic (VB) suit. The system now awaits the completion of the testing phase and the actual implementation (installation) at Competence. Some knowledge surrounded by the books was there but in real life is not like that got some practical knowledge and with this project started to explore my practical knowledge. There was not any binding while doing this project which clarifies that worked here independently.
There is nothing in this world which is free from drawbacks. My project also got some drawbacks. These are discussed below:
• The main problem related with drawbacks was found is a very short period of
• time. Because of a short time the project was not done with an organized way as it should be.
• Mainly testing part has some lacking.
• This software is one of the earliest developed real life problem and for that reason not properly organized whether it will be a time consuming or not.
7.2 Conclusion
While doing this project tried to put best effort on it and follow the standards, techniques. The target of database based software is not just to enter the records, but also to analyze and represent them to the management for making decisions and corrective plans. At the end of the Training Accounts Information System reports are produced to serve the management needs and provide them with accurate picture of the transaction records in summarized form. In fine, want to mention that here learned how to work in professional environment with challenges in the real development world, how to improve coding and design techniques and how to cope with different working situations. Throughout the whole development process got the chance to implement theoretical knowledge of computer science that learnt over last 4 years from respected faculty members of Independent University. Not only that, through report writing got to know how to compose professional and formal reports for any project or research works. After working in a real-life project, have grown a new respect and appreciation for this line of work.
