Adding and Deleting Datastore Columns

5-10 Oracle Fusion Middleware Developers Guide for Oracle Data Integrator reverse-engineering process or manually. For example with the Oracle technology, partitions are reverse-engineered using the RKM Oracle. The partitioning methods supported depend on the technology of the datastore. For example, for the Oracle technology the following partitioning methods are supported: Range, Hash, List. Once defined on a datastore, partitions can be selected when this datastore is used as a source or a target of an interface. Refer to Chapter 11, Working with Integration Interfaces for information. If using the common format designer, you can also create partitions when performing the Generate DDL operation.

5.5.1 Defining Manually Partitions and Sub-Partitions of Model Datastores

Partition information can be reverse-engineered along with the datastore structures or defined manually. To define manually partitions and sub-partitions for a datastore:

1. In the Models accordion, double-click the datastore for which you want to define

the partition or sub-partition. The Datastore Editor opens.

2. In the Partitions tab, enter the following details to define the partition and

sub-partition: ■ Partition by Select the partitioning method. This list displays the partitioning methods supported by the technology on which the model relies. ■ Sub-Partition by If you want to define sub-partitions in addition to partitions, select the sub-partitioning method. This list displays the partitioning methods supported by the technology on which the model relies.

3. Click Add Partition.

4. In the Name field, enter a name for the partition, for example: FY08.

5. In the Description field, enter a description for the partition, for example:

Operations for Fiscal Year 08.

6. If you want to add:

■ additional partitions, repeat steps 3 through 5. ■ a sub-partition of a selected partition, click Add Sub-Partition and repeat steps 4 and 5.

7. From the File menu, select Save.

5.6 Checking Data Quality in a Model

Data Quality control is essential in ensuring the overall consistency of the data in your information systems applications. Note: Standard reverse-engineering does not support the revers-engineering of partitions. To reverse-engineer partitions and sub-partitions, you have to use customized reverse-engineering.
