I am using TDM 126.96.36.199, and it t can’t merge two data models. They are relatively big with about 800 entities, 2000 relations and 12000 attributes, database is Oracle 11.2. I have free memory, and merge process uses only about 5% of CPU. It is very, very slow in this version, and after I have left it to finish overnight it just have crashed. I will try beta 5.2.38 to see if performance of the model’s merge was improved.
Is it possible in TDM to modify target database’s definitions for reverse and forward engineering like it is possible in PowerDesigner? If you can have some extensible attributes/properties that can be assigned to the objects of the specific databases then users could extend database definitions with something that isn’t yet supported by TDM official release. Like POstgresql has comments on sequences, and if it would be possible for users to extend metadata model for Postgresql and modify reverse engineering SQL scripts then this objects property could be captured in TDM and later used in forward engineering. I like it in PowerDesigner.
