What's involved in adding native support for new DBMS platforms, such as Snowflake?
SAP PowerDesigner allows you to create new DBMS profiles, which are XML-based descriptors of datatypes, reverse/forward engineering SQL syntax, and so on.
Does ER/Studio have a similar feature, or must we wait on the vendor to provide support for these new platforms?
Yes, ER/Studio does provide the capability to add datatypes and mappings for platforms that don't yet have full native support.
