Computerized system is a method of making use of the computer with other resources to perform tasks that will meet information need of an organization. Computerization is also a means of replacing the old system (manual system) with the new system, and will process large amount of data. The system is designed to achieve a great improvement in keeping Student information system record. This system also simplifies process of play when using the manual system with great speed and accuracy. The system does not allow merging of records when inquiring as in the case of the existing system. The system has the following advantages. It provides adequate security measures, so as to protect records from unauthorized use and disclosure. It reduces waste of time in processing data since computer is a machine capable of processing data quickly. It’s very simple to operate, what is required is only to train the users operating personal on how to use the system. It provides high degree of accuracy depending on the quality of data entered. It is said to be retable since its storage capacity is large and is capable of storing large amount of data. CHAPTER FOUR IMPLEMENTATION AND SYSTEM TESTING 4.1 INTRODUCTION This chapter is aimed at describing how the system is implemented, documented, along with requirement needed to implement the system and also described how the system was tested. 4.2 SYSTEM IMPLEMENTATION System implementation is the process of putting the designed system in operation. To implement any system, there is need to consider a certain requirement needed by the system. Likewise Student Information System needs some requirement before its implementation. The system is tested and documented, people are trained to operate and use the system, and organization converts the use of a newly developed system using any of the conversion approaches below: Direct Conversion: For small and straight forward system, but is highly risky. Problems may not be detected with this implementation strategy. Parallel Conversion: The existing system and the new system are operated simultaneously, until you have confident that the new system is working properly. This conversion is recommended because the existing system serves as a backup if the new system fails to operate as expected. In the case of fault from system development and also the result of the new system can be compared to the result of the existing system. Pilot Conversion: This involves changing to the new system in bits, which may be department by department. This is to avoid committing the resources of the system at once. Download 0.97 Mb.
