Hi Dirk,
it's not realy database independand ... the database underneath is SAP HANA, so the active table behing the DSO is a HANA table.
My idea is to document the DSOs in a LDM, and based on this LDM model generate a PDM model for HANA.
So in fact what I will have are:
1. Physical model (HANA) of the STAGING area
2. Logical model of the DSOs
3. Generated PDM (from LDM) for HANA DSO base tables
4. Data Movement Model defining the ETL between STAGING PDM and DSO PDM
When I'm still not sure, is how to model for example:
1. A constant in the DMM
2. A IF-THEN-ELSE in the DMM
as for now I would use Data Calculator for it, nut I'm not sure it's correct.
We will not generate any code from the DMM models ... it's only for documentation, linage/impact analysis purposes.
Any suggestions?
