Exam 2: Introduction to Database Development

Select the most appropriate statement about information systems development.

The first two phases of database development are concerned with the information content of the database,while the last two phases are concerned with the efficient implementation of the design.

Which of the following is a feature provided by prototyping tools?

Database replication,a technique to improve performance by having multiple copies of the database available to various user groups,is very seldom done in practice because it is too difficult to keep all the copies consistent.

The role of a database is to provide short-term memory for an information system.

Which one is not an advantage of prototyping?

In the traditional systems development life cycle,the __________________________ phase produces executable code,databases,and user documentation.

Normalization takes place during the following database development phase:

Because many physical design and distributed design decisions must be tested on a populated database,these last two phases of the development process are usually divided between systems design and systems implementation.

Data placement decisions usually occur in the distributed design phase of database development.

The decision to place each student's record next to the student's enrollment data on disk takes place in the following phase of Database Development:

In the traditional life cycle,the systems implementation phase begins when an information system becomes operational.

Which of the following is independent of the choice of a DBMS?

Conceptual data modeling takes place during:

Refinements to the conceptual data model usually occur in the logical database design phase.

Data Requirements are input to the following phase of Database Development:

The waterfall model characterizes the following systems development model:

A set of related components that work together to accomplish some objective is known as a(n)__________________.

A supplier shown with two different addresses in two parts of the database would violate:

In the traditional systems development life cycle,the __________________________ phase produces requirements describing processes,data,and environment interactions.
