Question
System Analysis and Design:
1) Describe a scenario in which the distribution of users determine the output technology.
2) What is the difference between gradual conversion and modular conversion?
3) At University, the course numbers are encoded as we discussed in class. What is the human reasoning for this encoding?
4) At the end of the project, why would an analyst perform another cost-benefit analysis if one were performed one to get the approval for the project? What has changed and why do this now?
Explanation / Answer
1. Discovering who will use the output technology is important because job requirements help in deciding whether the output methods are workin appropriate. Scenario where users detemine the technology or the software that implemented occurs in two cases. Firstly when a new installation is done and secondly, when any version is upgrade performed.
When the system is in the phase of go live based on the distribution of users and their satisfaction, output technology is determined.
2.Gradual, or phased, conversion attempts to combine the best features of the two previously mentioned plans, without incurring all the risks whereas Modular conversion uses the building of self-contained, operational subsystems to change from old systems to new in a gradual manner.This conversion method is arguably the least risk with respect to implementing the Spice Hotel database solution.
The greatest disadvantage is the time necessary for complete conversion to occur, as element by element of the current
Modular conversion uses the building of self-contained, operational subsystems to change from old systems to new in a gradual manner.As each module is modified and accepted, it is put into use. One advantage is that each module is thoroughly tested before being used. Another advantage is that users are familiar with each module as it becomes operational. Their feedback has helped determine the final attributes of the system. Object-oriented methodologies often use this approach.
3. Course numbers are encoded for the reason for security. In general every subject is allocated with a unique code which specifies the course structure and the semseter. Encoded code numbers esay the subject identification at the time of conducting exams and also helpful in online corrections.
4. Cost-benefit analysis is performed at the end of the project to verify the modifications or changes that have been done in the cut over plan that has opted at the time of the project approval. This gives the vivid picture regarding the project structure. This helps in performing a better interface structure at the next development project.
