Re: Just say no ...
a) No clue what a BIG database actually means (talking multi-TB through PB here).....
1) I have a sneaking suspicion that people like Google, Facebook and Amazon know a thing or two colossal datasets and massive concurrency and (bizarrely) they don't use Oracle to do it.
2) We're discussing County Councils. Half their work could be conducted with dBase III. Joining multiple million+ record tables is well within the capabilities of any number of cheaper (or free) RDBMS engines (certainly PostgreSQL or FireBird).
