Re: DB versions

Richard,

A roll your own variety of this shouldn't be too hard to implement.

What you would need:

A schema to build a mini data dictionary. Meta-data if you will, but not as complex as the images that term conjures up.

Store standard info about tables, indexes, columns, views, storage, sequences,etc. For stored code, just duplicate it in your mini-meta-data. ( hey, that kinda rolls off the tongue doesn't it :)

Add columns to your meta data for time series ( dates ), and revision number.

Take a snapshot ( not to be confused with oracle snapshots ) of the schema, include the current date/time and revision number on all objects.

You should have another table for storing a row for each baseline taken, with date, revision number and notes ( is this schema production ready? , etc )

You now have baseline data to compare against a schema. The SQL to check the differences is not very complicated, just a little time consuming to write. I've done it before and it's not too bad.

You will now have a valuable tool for determining if a schema matches a baseline or not, and will have it done long before you can get a a purchase order for a new piece of software to install,license, configure, etc.
