Introduction
Speedy and efficient information processing is crucial to our socially and highly developed technology. Computer can help the intolerable burden of handling the ever increasing amount or information with government department, public services and business concerns expected to contain because of their ability to analyze information as well as to retain, update and reproduce it because of their versality to present it in a variety of forms. This may also to some extent lead to problems occurring due to information explosion.
About Project
POST OFFICE works in every walk of our life. Through the automation of this system one can easily generate the information about the customer available and also about the old records.
For this efficient software the first and the foremost thing is that all the requirements should be known before hand and the developer should devote its effort for the completion of that requirement which are demanded by the customer should be fulfilled. This system can be used in various education departments and can distribute the copies of the system among the management and staff members for the required information of their customer.
This very handy project for any user and includes following features:-
● Having customer information and total amount payable.
● for the help of user it displays each and every detail about required topics
● Maintains all the old record for later reference
● Have provision for automatic update as per the status
● System must handle user enquiry
Software Development Life Cycle
The Software Development Life Cycle, as outlined by Edward Yourdon in his book modern structure analysis (1989) has been followed in this project with minor modifications. The modified life cycle is shown overleaf.
The life cycle consists of the following activities:
1) SURVEY- This activity is also known as feasibility study. It begins with a request from the user for a new system. It involves the following:
● Identify the responsible user for a new system.
● Clarify the user request
● Identify deficiencies in the current system
● Establish goals and objectives of new system
● Determine the feasibility for new system
● Prepare the project charter which will guide about the remainder of the project
2) SYSTEM ANALYSIS – The objective of the system analysis activity is to develop structured system specification for the proposed system. The structured system specification should describe what the proposed system would do; independent of the technology which will be used to implement these requirements. The structured system specification will be used to implement these requirements. The structured system specification will be called the essential model (also known as logical model).
The essential model may itself consist of multiple models, modeling different aspect of the system. Generally three models used for such purpose are:-
● DATA FLOW DIAGRAM (DFD) – It models the functioning of the system. DFD may consist of following
● Context diagram
● Leveled Data Flow Diagram
● Process specification for Elementary Bubble
● Data dictionary for the flows and stores on the DFD
● ENTITY RELATIONSHIP DIAGRAM – It models the functioning of the data and their relationship.
● STATE TRANSITION DIAGRAM – It models the time dependent behavior of the system.
3) PRLIMINARY DESIGN – This activity deals with certain design issues, which are to be finalized in consultation with user. The two most common design issues of relevance to the user are the automation boundary and the human machine interface. The output of the activity is the user implementation model. The major part of the user implementation model is the specification for the user interface of the proposed system. The user implementation model is also referred to as the physical model of the proposed system. The model, in addition to the essential model , defines the following for the proposed system:
● Automation boundary
● Report layouts
● Layouts of the source documents
● Screen Layouts for the data entry form
● Menu
4) SYSTEM DESIGN – System design involves transformation of the user implementation model into software design. The design specifications of the proposed system consist of mainly database schema.
5) IMPLEMENTATION – This activity includes programming, testing and integration of modules into a progressively more complete system.
6) ACCEPTANCE TEST GENERATION – This activity generates a set of data that can be used to test the new system before accepting it.
7) QUALITY ASSURANCE – Assurance is also known as final testing. This activity requires, as its input acceptance test data generated in acceptance test generation and an integrated system produced by implementation.
About the current system
Advantages of the current system
The project Post office management system is created in 4GL GUI based system so that it is easy to handle. It also increases the efficiency of the end user, because it will reduce the reluctant jobs, which are tedious to complete. The Post office management system also has automated capability to complete job, it automatically generates the reports, so it reduces the work manually.
Advantages of POST OFFICE MANAGEMENT SYSTEM:-
1. This system will improve the performance of the company.
2. It reduces the tedious jobs like reluctant work, long procedures, automated report generation, up to date information.
3. It will improve the Post Office Management, since all the information is available whenever required.
4. It provides quick processing thus helps in transaction and updating in master records can be performed in few records.
5. It allows easy generation of all types of reports.
6. It provides accurate output.
7. It gives fast answer of queries.
8. The amount of paper is reduced.
9. Better security
10. Economical.
11. Better Control.
Deficiencies of the manual system:
1. Lack of immediate retrieval of information - In manual system, lot of time is wasted in retrieving information. Much searching is required before required is found. This wastes a lot of time of the user as well as the person.
2. Lack of immediate information storage – In manual system, it is difficult to store information at proper place at that very moment. This is because the person is unable to quickly locate the place where the information is to be stored.
3. Prompts updating not possible – Changes are quite natural in all walks of life. Information and stored data also changes from time to time. These changes should be incorporated in the working also to keep the information up to date. However, bringing about changes through the manual system is a slow and tedious process because of which inaccurate information storage occurs.
4. Unplanned working – The manual system lacks the element of planned working. Records are not properly maintained. This creates a lot of problems at times like during information retrieval and storage
5. Insignificant generation of managerial and strategic reports. – In manual system, reports for management are difficult to be generated and strategic reports are impossible. This is because for these reports proper storage of information, its retrieval and its filtering are very important and very tough in manual system.
6. Accuracy – The manual system lacks accuracy in working and a number of operations may be performed incorrectly, the computations that are done in the organization may be incorrect and whatever are generated in the system may be inaccurate.
7. Reliability – The reliability of the manual system is considered to be low because of the above given reasons including the fact that ‘TO error is human’. Any task that is performed by men, always contain the risk of errors.
8. Redundancy of information – In manual system, particular information may be stored at a number of places, lending to redundancy. Redundancy of data or information creates a number of problems storage space is wasted; changes at one place are to be made at a number of places and so on.
