System Implementation In Software Project

System Implementation Project

Software Implementation Techniques 

After detailed system design we get a system design which can be transformed into implementation model. The goal coding is to implement the design in the best possible manner. Coding affects both testing and maintenance very deeply. The coding should be done in such a manner that the instead of getting the job of programmer simplified the task of testing and maintenance phase should get simplified. 

Various objectives of Coding are 

1. Programs developed in coding should be readable. 
2. They should execute efficiently. 
3. The problem should utilize less amount of memory. 
4. The programs should not be lengthy.

If the objectives are clearly specified before the programmers then while coding they try to achieve the specified objectives. To achieve these objectives some programming principles must be followed. 

System Implementation in Project 

The implementation is the final and important Phase in Project. It involves user training, system testing and successful running of the proposed system. Implementation includes all those activities that take place to convert from the old system to new one. After completion of the system design and coding, the analyst, user and the management, evaluates the system to ensure that it fulfills all the goals. 

Thus the implementation is the stage of project where the system design is turned into a system. 

Implementation Plan 

It begins with preparing a plan for the implementation for the system. According to this plan the other activities are to be carried out. 

In this plan discussed has been made regarding the equipment, resources available and how to test the activities. 

System Testing 

It is an unrealistic attempt to test the system as a single unit. Thus the functions of the system are tested and the functions are put together, called modules and tested. 

Furthermore, the modules are added to form a subsystem.  These sub system are also tested. Then these subsystems are integrated to form the main system. Finally, the acceptance test with real data is performed for user satisfaction. The methodology used in testing the system is top-down testing. 

In this Phase, actual data are obtained from the schedule department and fed into the computer. After this the output obtained is compared with the manually obtained data for accuracy. The reports are also tested in the same. 

System Security 

The password setting of entering the system is check by user name and password has checked the unauthorized user cannot enter the system that manages sensitive information is target for improper penetration. 

Example 

Visual Basic provides adequate system security from its part. Unsecured system password requirement full resource security, restricted access to the levels of security offered by Visual Basic.
