Match each of the following terms with its corresponding definition. -A relationship between the instances of one entity type

Which of the following is produced and analyzed during conceptual data modeling?

Since a name represents a set of entities, it is plural on an entity-relationship diagram.

When generating alternative design strategies, low-end solutions may not involve computer technology at all.

Match each of the following terms with its corresponding definition. -A simultaneous relationship among instances of three entity types

A true data entity will have many possible instances, each with a distinguishing characteristic, as well as one or more other descriptive pieces of data.

Selecting the best alternative system involves:

A "many" maximum cardinality is noted on the E-R diagram by:

On an entity-relationship diagram, a rectangle represents a(n):

The minimum requirements for the new system are called:

The primary deliverable for the conceptual data-modeling step within the analysis phase is an entity-relationship diagram.

A faculty identification number could be used as an identifier.

A relationship between the instances of one entity type is a:

Features that everyone agrees are necessary to solve the problem or meet the opportunity are called:

Dividing requirements into different sets of capabilities, ranging from the bare minimum that users would accept to the most elaborate and advanced system the company could afford to develop occurs during the:

When selecting an identifier, one should:

Briefly identify the four entity-relationship diagrams that are produced and analyzed during conceptual data modeling.

Asking system users and business managers "How many instances of each object might exist?" would help determine:

The minimum requirements for a new system are also its mandatory features.
