Creating an ERD from a PDM
To generate a Entity Relation diagram from a physical data model:
1 Open a physical diagram.
2 Choose Dictionary > Create Data Model > Logical Model.
Options in the displayed dialog box are:
Diagram Name
The default suggestion is the name of the source PDM.
Spaces for - and _
Select this to replace hyphens and underscores in the physical names with spaces in the logical names.
Strip Common Column Name Prefix
Select to remove identical prefixes from the column names when creating attributes and data elements. For example:
Column name
Stripped attribute/data element name.
Cust_ID ==>
ID
Cust_Name ==>
Name
Note Stripping prefixes might cause collisions with existing data elements.
