Other databases allow one to store comments describing each field in a table
definition. These are stored in the database. In addition, one can store
comments about the table. Examples include MS SQL Server and MS Access.

I'm using activestate perl on WinXP but I'm sure this applies to all

I have 100K job posting records and 40K job title records. There is a M:M

What is the best way to design a junction or link table? Do I need to create
a primary key?
My thought was no primary key, just two indices on each foreign key
