Tugas – Essay : System Design
1. ________________________ is defined as those tasks that focus on the specification of a
detailed computer-based solution. It is also called physical design.
2. Information systems design is also called _____________ design.
3. ____________________, ______________________ and ____________________ are
examples of model-driven approaches.
4. Synonyms for modern structured design are: ___________________________ and.
5. When modules are ___________________ cohesive, each module should accomplish one
and only one function. This makes the modules reusable in future programs.
6. When modules are ______________________ coupled, modules are minimally dependent on
one another. This minimizes the effect that future changes in one module will have on
other modules.
7. A(n) __________________________________ (advantage or disadvantage) of prototyping is
that it helps end-users to visualize how a system will work, and hence help then to more
fully know their requirements.
8. An advantage of prototypes is that they are an ___________, not __________, model that
end-users can see, touch, feel and experience.
9. A(n) ____________________________ (advantage or disadvantage) of prototyping is that
the scope and complexity of the system can quickly expand beyond original plans. This can
easily get out of control.
10. Rapid application development (RAD) is the merger of various _____________ techniques
(especially the data-driven information engineering) with _____________ techniques and
_______________________ techniques to accelerate systems development.
11. An application architecture defines the technologies to be used by (and used to build)
one, more, or all information systems in terms of its __________, ___________,
_____________, and ___________ components.
12. The physical data flow diagram (PDFD) is used to establish the physical _______________
and ________________ across a network.
13. Issues to be addressed during _________________ include: data structures and their
impact on performance and flexibility; record size and storage volume requirements;
internal controls to ensure proper security; and disaster recovery techniques.
14. In the procurement phase, the first task is to ___________________. This identifies
specifications that are important to the software and/or hardware that is to be selected.
These requirements specify the functionality, features, and critical performance
parameters. The second task is to ________________________.
