    Unanswered: 15 Primary Keys for a fact table

    Hi,

    I've a developer requesting for 15 primary keys for a fact table. This table will possibly join with many dimension tables.

    Is this a good move ?

    And if there's bulk loading into this table, will it cause any problem ?

    Advice pls...TIA

    You can only have one Primary Key per table. Do you mean one PK with 15 columns, or 15 foreign keys (or both)?
