3 In the design of the registration system, the design should contain distinct
representations of data, architecture, interfaces and components. For example, the
different interfaces that will be used to capture the data in the registration process,
such as the student’s personal information, should be included during the design
process.
4 In the registration system, the design should include a data structure that is both
feasible to implement and should consider existing legacy systems with which the
system should communicate.
5 The design should lead to components that exhibit independent functional
characteristics – therefore in the registration system the component that is extracted
from the different processes within the system should be of such a nature that it is
not dependent on the output from other components.
6 Similar for the remaining three concepts for quality design found on page 262.
8 Discuss how you will use a data-centred architecture style in a university
registration system. (2)
A data-centred architecture style is one in which a data store (such as a file or database)
resides at the centre of the architecture. In the registration system, the student database is
typical at the centre of the system where not only the student system may access the data,
but also other systems such as the financial system. It is important that data reside in only
one location and is not duplicated in different systems.
9 Discuss how you will implement integration testing in a new university registration
system. (10)
Integration testing is a systematic technique for constructing the software architecture while at
the same time conducting tests to uncover errors associated with interfacing. In the
registration system integration testing can be used by taking the unit’s tested components
and combining these components into one structure. For example, in the registration process
the verification of matriculation results and the comparison of matriculation results with what
the student intends to study can be developed as two different components. After unit
component testing, these components can be integrated into one system (together with other
components) through one interface and can then be tested.
10 Discuss how you will use black box or white box testing with a new university
registration system. (5)
White box testing is a test case design philosophy that uses the control structure described as
part of component-level design to derive test cases. In other words, a specific part of the
