Exam 9: Designing Databases

A manner that represents how an object acts and reacts best describes:

When using the normalized relation notation, the primary key attribute is indicated by a dashed underline.

A well-structured relation contains data about two or more entities.

Identify and briefly describe two techniques used by eXtreme Programming to continually improve the quality of the design.

What is the Unified Modeling Language?

When transforming an E-R diagram into normalized relations, the identifier of the entity type becomes:

Normalization is based on an analysis of weak entities.

Key physical database design decisions typically do not include:

On a state diagram, a state is considered to span across a period of time.

Agile software development values individuals and interactions over processes and tools.

On a use-case diagram, an "extends relationship" extends a use case by capturing additional actions or behaviors that need to be performed.

Each entity type in an ER Diagram becomes an attribute.

In UML, an object class is represented by:

The three key principles of Agile Methodologies include a focus on adaptive rather than predictive methodologies, a focus on people rather than roles, and a focus on a self-adaptive process.

Traditional approaches work best when the target system will operate in a volatile and fluid environment.

The Iteration Planning Game consists of:

A class that has no direct instances, but whose descendants may have direct instances best defines:

Another name for a unary relationship is a:

During physical database design, relations from logical database design are translated into computer file specifications.

The convergence of the object-oriented approach and the Internet economy set the stage for the Agile Methodologies.
