You can modify an object's properties from its property sheet. To open an index property sheet, double-click its diagram symbol or its Browser entry. The following sections detail the property sheet tabs that contain the properties most commonly entered for indexes.
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 index |
Stereotype |
Sub-classification used to extend the semantics of an object without changing its structure; it can be predefined or user-defined |
Owner |
Specifies the name of index owner. You choose an owner from a list of users, the index and table owners can be identical or different. An index can only have one owner at a time. This is normally the index creator. Some DBMS allow you to define an index owner, either identical or different from the table owner. If the DBMS of the current model does not support index owners, the table owner will be automatically assigned to the index after switching to a DBMS that supports index owners. |
Table |
Specifies the table to index |
Type |
[Sybase® IQ, and Oracle only] Specifies the type of index. You can choose between:
|
Unique |
Specifies whether an index is a unique index |
Cluster |
Specifies that the index is a clustered index. A table cannot have more than one clustered index. Note that clusters in Oracle 11 and higher are modeled as extended objects with a <<Cluster>> stereotype. For more information, see DBMS-Specific Features. |
