Exam 9: Database Design

After testing is concluded,the final is reviewed and printed and end users are trained.

During the implementation phase of the Systems Development Life Cycle (SDLC),the hardware,database management system (DBMS)software,and application programs are installed,and the database design is implemented.

Evaluation of database performance is rendered easier by the fact there are no standards to measure it.

In the Systems Development Life Cycle (SDLC),the design of the system's processes begins in the detailed systems design phase.

An initial assessment of the information flow-and-extent requirements must be made during the portion of the Systems Development Life Cycle (SDLC).

In the detailed systems design phase of the Systems Development Life Cycle (SDLC),steps are laid out for the conversion of a database from an old system to a new system.

The maintenance and evolution phase of the Database Life Cycle (DBLC)involves .

The main purpose of a backup is to guarantee database restoration following a hardware or software failure.

What are the factors affecting the purchasing decision for DBMS software?

In the Systems Development Life Cycle (SDLC),problems defined during the planning phase are examined in greater detail during the analysis phase.

The detailed systems design phase of the Systems Development Life Cycle (SDLC)includes all the necessary technical specifications for the screens,menus,reports,and other devices used to make the system more efficient.

The overall purpose of the database initial study is to create the conceptual design.

The Systems Development Life Cycle (SDLC)traces the history of an information system.

Physical design becomes simpler when data is distributed at different locations.

The first step in is to discover the data element characteristics.

To analyze the company situation,the database designer must discover what the company's operational components are,how they function,and how they interact.

The stage uses data modeling to create an abstract database structure that represents real-world objects in the most realistic way possible.

The last step in the Database Life Cycle (DBLC)is .

The system's defines the extent of the design according to operational requirements.

Which of the following is a hardware-induced database failure?
