since SQL89 standard lot of things got standartized but still there
are more things to unify. One of them is metadata (system tables that
a given DBMS uses) processing. I want to ask if there is going to be any standard on
that ? Namely any unified way (for different DBMSs) to extract and
modify metadata about the user database - primary keys, foreign keys, info on
cascade updates/deletes settings, default values, ranges of allowed values and so on.
