I am building a flex/bison-based SQL parser that looks for all selects having group by clauses without order by clauses as a risk reduction for migrating to Sybase 15. The parser works quite well and now I am now using the Ignite repository as a very good source of SQL text that our databases have seen. The CONST_NN tables have these data. My question is "Is there a document/map describing the table relationships and column definitions for the Ignite/DPA repository?"
