Rational Developer for System z, Version 7.6

Database Block Definition tab

In the Definition, you specify the logical information necessary for the source language generation.

External name
This name is necessary upon generation.

It is the physical name of the generated DDL (Data Description Language).

Block type
Select the Block type in the drop-down list.
Note: For hierarchical or network databases, entering the definitive Block type is not required upon creation. Selecting a network or hierarchical structure is enough at this point. A specific 'physical' type must be selected when generating the Data Description Language (DDL).

The first two values of the list are identical, except that with the second value (DR: DL/1 Physical DBD), only the Data Elements referenced as access keys in the Segment description are generated in the FIELD...... statements.

Changing the Block type is allowed only inside the same category (ex: another type inside the Hierarchical type).

Schema name
It is the physical name of the schema to which the given block is attached.

Enter this name on 8 characters maximum.

This name is only used for SE-type Blocks (Group of Sets) and for CODASYL Blocks.

It is necessary at generation time if the Block is a SUB-SCHEMA or a DMCL.

This field is not used if the Block is a schema.

Version number
You enter here the version number of the Database system:
  • 3000 for NONSTOP SQL Version C30
  • 5000 for RDMS 1100 Version 5RA4
  • 7000 for ORACLE V7
  • Blank for other systems, all versions.
