Every entity must be related to another entity.

Relationships link entities together.

A one-to-many relationship means one entity instance can be associated with multiple instances of another entity.

Relationships are usually represented with diamonds.

Attributes define properties of entities.

Primary keys uniquely identify entity instances.

Attributes are represented as ovals in an ERD.

Which of the following descriptions of cardinality is incorrect?

Cardinality is always optional in ERDs.

Cardinality defines the number of entity instances that can be associated with another entity.

A one-to-one relationship means each entity instance relates to exactly one instance of another entity.

Many-to-many relationships allow multiple instances of one entity to be associated with multiple instances of another entity.

Which of these statements about foreign keys in an ERD is incorrect?

A foreign key must always be unique.

A foreign key establishes a relationship between two entities.

Foreign keys help maintain referential integrity in a database.

A foreign key is an attribute in one entity that references the primary key of another entity.

Which of the following is NOT true about associative entities?

They do not need a primary key.

They are used to resolve many-to-many relationships.

They store attributes related to relationships.

They act as a bridge between two entities.

Which of the following is NOT a correct characteristic of a process in a DFD?

Processes in a DFD represent physical components like computers.

A process transforms inputs into outputs.

A process must have at least one incoming and one outgoing data flow.

A process is labeled with a verb-noun phrase, like 'Process Order.'

Which of these is NOT a correct description of a data store in a DFD?

A data store must always be connected to an external entity.

A data store represents stored data that processes can access.

Data stores are represented as open-ended rectangles.

Data stores hold information for future processing.

Which of the following is NOT a valid DFD rule?

Processes can be named with a noun only.

Every process must have at least one input and one output.

Data cannot flow directly from one external entity to another.

Data stores must be linked to at least one process.

Which of these DFD components is incorrectly described?

Data stores are used to transfer data between two external entities.

Processes transform data within the system.

External entities interact with the system but do not process data.

Data flows represent the movement of data within the system.

Which of the following is NOT a valid way to represent data flow in a DFD?

Using circles to represent data flow

Showing the flow of information

Which of the following is NOT true about external entities in a DFD?

External entities process data before sending it to the system.

They represent sources or destinations of data.

They can be organizations, people, or external systems.

They are typically represented as rectangles in a DFD.

Which of these statements about DFDs is incorrect?

A process in a DFD must always have an outgoing data flow.

A context diagram is the highest-level DFD.

Level-0 DFDs break down a system into major processes.

DFDs help in understanding data movement within a system.

Which of the following is NOT a purpose of a Data Flow Diagram?
