Sybase ASE

To create a PDM with support for features specific to the Sybase ASE DBMS family, select the appropriate version in the DBMS field of the New Model dialog. To view these extensions to the PowerDesigner metamodel in the Resource Editor, select Database > Edit Current DBMS and expand the Profile node.

Note: The DBMS definition file for Sybase AS Enterprise v12.5.3a is deprecated.

The following sections list the extensions provided for ASE.

Note: We do not provide documentation for the properties on the Physical Options and certain other tabs, though minimal information is available for them in the Resource Editor. For information about these properties, consult your DBMS reference documentation.

Tables

Description

Partition
Indicates how records are distributed on table partitions. You must choose between:
  • Range - partitioned according to specified ranges of values in the partitioning column or columns (Scripting name: PartitionByRange).

  • List - partitioned according to literal values specified in the named column (Scripting name: PartitionByList).
  • Round robin - partitioned in a sequential manner (Scripting name: PartitionByRoundrobin).

Each of the partitioning methods enables a list of partitions for you to complete, except round robin by partition number, which requires only that you specify the number of available partitions on a particular storage.
