SAP HANA

To create a PDM with support for features specific to the SAP HANA® 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.

PowerDesigner supports round trip reverse-engineering and generation of SAP HANA® v1.0 SP07 tables and analytic and attribute views.

The following sections list the extensions provided for SAP HANA.

Tables

The following extensions are available on the General tab:

Name

Description

Type
Specifies the table type. You can choose between:
  • Row - [default] If the majority of table access involves selecting a few records, with all attributes selected, ROW-based storage is preferable.
  • Column - If the majority of table access will be through a large number of tuples, with only a few selected attributes, COLUMN-based storage should be used.
  • History column - Creates a table with a session type HISTORY, to support time travel queries, which are queries against historical states of the database.
  • Global temporary - The table definition is globally available while data is visible only to the current session. The table is truncated at the end of the session.
  • Local temporary - The table definition and data is visible only to the current session. The table is truncated at the end of the session.

Scripting name: FullType

The following extensions are available on the HANA tab:

Name

Description

Logging type
Specifies whether table logging is activated. You can choose between:
  • logging - [default]
  • nologging - specifies that logging is deactivated. As a result, the definition of the table is persistent and globally available and data is temporary and global. The resource manager should therefore explicitly drop a NOLOGGING table.

Scripting name: LoggingType

Retention period

[if nologging] Specifies the retention time in seconds of the table created as nologging.

Scripting name: Retention
Auto-Merge

Specifies that automatic delta merge is triggered.

Scripting name: FullTableOptions

The following extensions are available on the Partitions tab:

Name

Description
Type
Specifies the partition scheme type:
  • Hash - Distributes rows to partitions equally for load balancing and to overcome the 2 billion row limitation. Specify an expression listing the columns to partition on and the number of partitions to create. You may specify a second scheme of type Hash or Range.
  • Range - Creates partitions for specific values or value ranges. Specify an expression and range specifier.
  • RoundRobin - Distributes rows to partitions equally without specifying partitioning columns. Specify the number of partitions to create. You may specify a second scheme of type Range.
