Exam 9: Designing Databases

Appendix B Agile Methodologies -The developer-as-artist systems development era was marked by a lack of documentation and development tools and by a high degree of dependence on the developer for the continued ongoing operation of the system he/she had created.

Abstracting common features among multiple classes, as well as the relationships they participate in, is called generalization.

Generally speaking, logical and physical database design is performed in parallel with other systems design steps.

A notation that allows the modeler to specify, visualize, and construct the artifacts of software systems, as well as business models, best defines:

Making a program simpler after adding a new feature best defines:

In which object-oriented systems development life cycle phase are the application-oriented analysis models adapted and refined to suit the target implementation environment?

Designing the database for an Internet-based electronic commerce application differs significantly from the process followed when designing the database for other types of applications.

During the Iteration Planning Game's commitment phase:

Which of the following is NOT a True statement regarding a relation?

During logic modeling, the normalized data requirements from all user interfaces are combined into one consolidated logical database model.

An Agile Methodology is recommended if your project involves unpredictable or dynamic requirements.

Agile Methodologies focus on the roles that people perform.

During eXtreme Programming, programmers are the only participants in the Planning Game.

During eXtreme Programming:

A type of message in which the caller has to wait for the receiving object to finish executing the called operation before it can resume execution itself is a(n):

Indexes should be used generously for databases intended primarily to support data retrievals.

A diagram that depicts a teacher and student as actors for a system is called a:

The semantic constraint specifying that no instance can be an instance of more than one subclass at the same time is:

On a class diagram, an exclamation point represents a multiplicity with an infinite upper bound.

Denormalization reduces the chance of errors introduced by normalizing relations.
