Define a DB2 LUW Table

Use the DB2 for LUW Table Editor to create a table, or work with table properties for an existing DB2 LUW table.

To define a DB2 LUW table

1. Right-click a Table in the Model Explorer and select Properties.

   Note: This field applies to DB2 for LUW version 9.7 only.

   Physical Only

   In a Logical/Physical model, specifies that the table does not appear on the logical side as an entity.

   Generate

   Specifies whether or not to generate DDL for this object during Forward Engineering.

3. Click the Dimensional tab and work with the following options:

   Note: This tab is displayed when you select the Is Dimensional check box on the General tab of the Model Editor.

   Dimensional Notation Rule Type

   Specifies the role assigned to the table for dimensional modeling. Select from the drop-down list; valid values are Fact, Dimension, and Outrigger.

   Dimensional Notation Update Type

   Specifies the type of update you want to use to update dimensional notations. Select from the drop-down list; valid values are Fixed, Type 1, Type 2, and Type 3.

4. Click the Data Movement Rule tab and work with the following options:

   Note: This tab is displayed when you select the Data Movement check box on the General tab of the Model Editor.

   Backup Rule

   Recovery Rule

   Archive Rule

   Purge Rule

   Sequence Ending Value

   Specifies the constant value at the higher end of the range for column-name.

   For the Dimension Organization Type:

   Dimension Groups

   Specifies a dimension for each column or group of columns that you have used to cluster the table data.

7. Click the Tablespace tab and work with the following options:

   Table Tablespaces

   Specifies the name of the tablespace where you want to store the table.
