Hi,
Without details:
i store every point in different record
And have expression index with distance to constant point. Together this is quite simple

How do you find area in area?
Are you storing polygon data in blob, then parse it via STORED PROCEDURE in P-SQL and then test for overlapping?
It is probably doable but not very convenient and a lot slower then built in solution would be.
