Hi Everyone,

We are implementing the dimensional modelling and we have debate going on to use DB sequence (Oracle) to generate surrogate key or use the state file.

Could you guys please let me know on what factors we have to consider.

Thanks in Advance

According to me it is better to use a state file for surrogate key generation.Because for DB sequence each time it hits the database.

If your process is the only one that will ever load the table in question then state file should be ok. If there is a chance that other applications may start entering data, then a db sequence object if preferable.

I agree with DSguru2B. We use db sequence only for those that require inserts from various regions.

Thanks for your replys.
