Summarize of Software Engineering Theory and Practice
The Summarize of customer wants and needs before we can build a system to help solve the problem. No matter how many people are involved in software development, the roles played throughout the life of the project can be distinguished. One development team will be made up with these members: requirement analysts, designers, programmers lines, testers, trainers, maintenance team, librarians, configuration management.
Then we are going to know the elements of system. We describe a system by naming its parts and then identifying how the component parts are related to one another. An activity is something that happens in a system, the elements involved in the activities are called objects or entities. Usually, these objects are related to each other in some way. Once entities and activities are defined, we match the entities with their activities. Some items from one system are used by activities outside the scope of the system being examined. We say they cross the system boundary.
After knowing the elements of a system, let us look at how to build it. Let me introduce Wasserman’s eight fundamental notions in software engineering form the ban’s for an effective discipline of software engineering: Abstraction, Analysis and Design Methods and Notations, User interface prototyping
