Exam 9: Process Modeling

In Structured English, when in doubt, user readability should take priority over programmer preferences.

A process is work performed on, or in response to, incoming data flows or conditions. A synonym is transform.

A compound data flow is a data flow that consists of other data flows.

Logical processes are work or actions that must be performed no matter how you implement the systems.

Gray holes are caused by:

Processes must be distributed to locations where work is to be performed.

A data flow diagram is a process model.

A set of related and ongoing activities in a business is known as:

A process that has inputs but no outputs is known as:

___________________________________ is the synchronizing of data flow diagrams at different levels of detail to preserve consistency and completeness of the models.

Structured English is very precise and requires a strict adherence to syntax rules so that it can be translated for specifications to programming code directly.

Data flows are data in motion; data stores are data at rest.

An event diagram is a composite diagram that combines multiple events into a single processing unit.

Each ___________________ process is (or will be) implemented as one or more _________________ processes that may include work performed by people, work performed by robots or machines, or work performed by computer software.

Data models illustrate the essential work to be performed by the system as a whole.

Physical processes are work or actions that must be performed no matter how you implement the systems.

If data modeling is done before process modeling, the agents on the DFD can be pulled from the entity relationship diagram.

External events are so named because they are initiated by external agents.

A logical unit of work that must be completed as a whole is known as:

The data type for an attribute defines what class of data can be stored in that attribute.
