You can modify an object's properties from its property sheet. To open a data item property sheet, double-click its Browser entry in the Data Items 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, which may be abbreviated, and should not generally include spaces. |
| Comment | Specifies a descriptive label for the data item. |
| Stereotype | Sub-classification used to extend the semantics of an object without changing its structure; it can be predefined or user-defined. |
| Data type | Specifies the code indicating the data format, such as N for numeric or A for alphanumeric, followed by the number of characters. |
| Length | Specifies the maximum number of characters. |
| Precision | Specifies the number of places after the decimal point, for data values that can take a decimal point. |
| Domain | Specifies the name of the associated domain (See "Domains (CDM/LDM/PDM)" in the Building Physical Diagrams chapter). If you attach a data item to a domain, the domain supplies a data type to the data item, and can also apply length, decimal precision, and check parameters. |
