True/False Indicate whether the statement is true or false. ____ 1. The high-level design that defines the overall structure of a system is called architectural design. ____ 2. Event tables are not useful when moving from analysis to design in object-oriented analysis (OOA). ____ 3. During analysis, analysts build models to represent the real world and to understand the desired business pro- cesses and the information used in those processes. ____ 4. The activities identified in the design phase of the systems development life cycle (SDLC) provide an over- view of the design process. ____ 5. The structured approach to systems development is a new technique that has become widely used since the late 1980s. ____ 6. Important technical issues arise when making the system operate over a network, such as reliability, security, throughput, and synchronization. ____ 7. Designing the application architecture involves specifying in detail how each system activity will actually be carried out. ____ 8. When creating tracking logs for open issues and unresolved problems, it is a bad idea to make these logs available to all team members. ____ 9. To start the design process, the analyst partitions the entire system into its major components, because an in- formation system is much too complex to design at once. ____ 10. Analysis and modeling require very limited user involvement to explain the requirements and to verify that the models are accurate. ____ 11. A critical aspect of the information system is the quality of the user interface. ____ 12. The objective of the design phase is to define, organize, and structure the components of the final solution system that will serve as a blueprint for construction. ____ 13. The key question to answer with the design of the user interface activity is, “Have we specified in detail how all users will interact with the system?” ____ 14. The key question to answer for the prototype for design details activity is, “Have we specified in detail how we can be sure that the system operates correctly and the data maintained by the system is safe and secure?” ____ 15. A client in the client/server architecture is a process, model, or computer that provides services over a net- work. ____ 16. Three-layer architecture is a client/server architecture that divides an application into the view layer, business logic layer, and data layer. ____ 17. In three-layer architecture, the data layer implements the rules and procedures of business processing. ____ 18. Web services architecture is a client/server architecture that packages software into server processes that can be accessed via the Web protocols. ____ 19. Internet and Web technologies are not appropriate for implementing information systems. ____ 20.
