ACCTG 1 Lecture Notes - Lecture 9: Insulin Pump, Maintainability, Data Collection System
Document Summary
Using appropriate methods to provide correct (and good) solutions. Maintainability software should be written in such a way so that it can evolve to meet the changing needs of customers. Dependability and security dependable software should not cause physical or economic damage in the event of system failure. Malicious users should not be able to access or damage the system. Efficiency software should not make wasteful use of system resources such as memory and processor cycles. Efficiency therefore includes responsiveness, processing time, memory utilization, etc. Acceptability software must be acceptable to the type of users for which it is designed. This means that it must be understandable, usable, and compatible with other systems that they use. System modelling represents a system using graphical notation, which is now almost always based on notation is the uml. It helps the analyst to understand the functionality of the system and models are used to communicate with customers.
