Measurement Properties

Measurements allow metrics to be defined for model objects, indicating the value of some object attribute. For example, they may be used to hold actual, estimated, or planned values for the size of a table, the number of rows in a table, the number of pages in an index, the number of different values in a column, and so on. This flexibility allows for product or project extensions, without changing the model.

Name: Name of the measurement object.

Comment: Optional descriptive comment text.

Notes: Optional note text, such as background information or implementation notes.

Value: Numeric value associated with the measure. Example: 10 if the measure is for 10 meters

Unit: Unit of measurement associated with the value. Example: Meter

Type: Type of value: Measure (measured), Estimate (estimated), Plan (planned), Minimum, Maximum, or Average.

Creation Date: The date when the measurement object was established.

Effective Date: The date when the measurement object is effective. For measured values, the effective and creation dates should be the same. For estimated actual values, the creation date may be later than the effective date. For planned values, the effective date is normally later than the creation date.

Summary: Displays read-only summary information.
