Yeah, study the old database until you understand what tables hold what data. When you understand that, the solution should be clear.

Or, work with a sub-set of data if that helps. Or, come-up with some new data. Fit that data into the old database and into the new. Now write code that will convert that data from the old to the new. That code should generally work for all the old data. If it doesn't, then fix it.

>I have recently inherited a database that was designed several years ago (at least 8 yrs) by someone who thought they knew about relational databases. My job is to normalize the database. The problem is that the database has over 8 years of data! I have the new database designed, but I am having trouble fitting the old database records into the new structure!
