Universe File

List,

Does anyone know how to decipher the contents of the Universe Database.

Specifically I am looking at the Exchange, Stock, and Future tables.

For Example, in the Stock Table, I would like to know what Vendor and
Data Vendor signify, as there are MANY duplicate entries.

Similarly for Futures, it has MANY MANY duplicates of the symbol, and I
would like to understand what the real difference between them is.  I do
understand the "uniqueness" of the key fields (Symbol, Data vendor,
Exchange), but want to understand the fields.

Any help is greatly appreciated.

THANKS.

Blair

P.S.  I am on digest version, so feel free to respond directly.
