In order to relate two tables of information, you need a value that ties them together, a value that is the same in each. If you give each company in the CompanyName table a unique ID, you then store those ID values in the ShareRate table with records containing containing respective companies' share rates. Thus, when you fetch rows of data from the ShareRate table, you then use the ID column to fetch the corresponding company name from the other table. This will work whether you are relating two tables in one database or you are relating tables in different databases.
