Exam 9: Process Modeling

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

Simple condition steps can be translated into programming language as a For loop.

A(n) _________________________ flow represents a condition or non-data event that triggers a process.

A synonym for external agent is external entity.

A model is a representation of reality

Data structures are non-specific arrangements of data that define data in a data store.

Elementary processes are discrete, detailed activities or tasks required to complete the response to an event.

A decomposition diagram is essentially a planning tool for more detailed process models, namely, data flow diagrams.

A data flow can connect pass data directly from one data store to another data store.

In a data flow diagram, rounded rectangles are used to represent processes.

Use case analysis is the process of identifying the actors who interact and use a system independent of how they are using the system.

A conditional structure specifies that a set of steps should be repeated based on some stated condition.

A control flow is a special data flow that has both inputs and outputs.

A model that shows what a system is and what it does, as well as how it does it, is:

During decomposition, each level of abstraction reveals more or less detail as desired, about the overall system or a subset of that system

Event partitioning factors a system into different databases based on how information is used and where it is stored.

A restriction of Structured English is that only names that have been defined in the project dictionary may be used.

An iteration structure specifies that a set of steps should be repeated based on some stated condition.

Data _______________________________ requires that a data flow contain only the data that is truly needed by the receiving process.

An entity relationship diagram (ERD) is a tool that depicts the flow of data through a system and the work or processing performed by that system.
