Data Properties

You can modify an object's properties from its property sheet. To open a data property sheet, double-click its name in the List of Data or its Browser entry in the Data folder.

The General tab contains the following properties:

Property	Description
Name	Specifies the name of the item, which should be clear and meaningful, and should convey the item's purpose to non-technical users.
Code	Specifies the technical name of the object, which is used for generating code or scripts.
Comment	Specifies a descriptive comment for the object.
Type	Specifies the type of the data. The following types are available: Undefined – [default]. Elementary data – atomic pieces of data, which are comparable to entity attributes, table columns, or class attributes such as a date, name, or ID. Structured data – more complex data that can be decomposed into sub-data, which are comparable to entities, tables, or classes, such as user, customer, or product.
Stereotype	Extends the semantics of the object. You can enter a stereotype directly in this field, or add stereotypes to the list by specifying them in an extension file.
Definition	Specifies the external PowerDesigner model object that models the data in more detail. Use the tools to the right of the list to browse the complete tree of available objects or view the properties of the selected object. For more information, see Linking Data to an External Model Object.

Sub-Data Tab

The Sub-Data tab is available only for data objects with the structured data type, and lists the data objects into which the structured data object is decomposed. You can add or create sub-data using the Add Objects and Create an Object tools.

Note:

You can click the Dependencies tab of a sub-data property sheet to display the data of which it is a part.
