A web service is a standard approach to making a reusable component available and accessible across the web activity-location matrix:Rows are system activities from event table、Columns are physical locations Alpha version – incomplete testing version Ambiguous requirements interpreted in different ways by developers and users. Ambiguous requirements interpreted in different ways by developers and users. Beta version – end-user testing version CASE’s fullname is Computer-Aided Software Engineering. Client/Server Architecture Advantage – deployment flexibility Client/Server Architecture Disadvantage – complexity Client/server divides programs into two types:Server、Client. Cohesion – qualitative measure of consistency of functions within a single class Controls are needed for all other design activities:User interface、System interface、Application architecture、Database and Network design. CORBA is an international standard for an Object Request Broker - middleware to manage communications between distributed objects. Coupling – qualitative measure of how closely classes in a design class diagram are linked CRUD – create, read, update, and delete Data dictionary is repository for definitions of data flows, data stores, and data elements Data flow diagrams (DFDs) are decomposed into additional diagrams to provide multiple levels of detail Deployment environment definition bridges analysis and design:Hardware、System software、Networking Design class diagram specifically defines software classes Design is process of describing, organizing, and structuring system components at architectural design level and detailed design level Design process activities include Architectural design、Abstract specification、Interface design、Component design、Data structure design、Algorithm design Domain model class diagram shows conceptual classes in users’ work environment Early increments act as a prototype to help elicit requirements for later increments. Engineers should be aware of loca
