Apropos of this conversation, I'd like to start up a list of frequently mis-applied tags (e.g. schema being used for data modelling questions that should be tagged database-design). Could we please add a list of tags in the answers, along with the ways they're mis-applied and what to re-tag as in the various cases.
I'll start with:
- schema used for data modelling questions. These should be tagged database-design. Questions about schemas (namespace/ownership of tables and other DB objects in various DBMS platforms) should retain the schema tag.
As we add answers I'll make up a link farm in the question that points out to the more detailed discussions in the answers, where the actual use of the tag can be discussed and written up in detail.
