That's a problem but it's manageable. If your data comes from multiple tables 
you do need to understand the relationships between them. You also need to 
understand the difference between tables and queries/views and the terminology 
used by both databases. Check which tables have indexes. Check whether the 
system you are extracting data from enforces any validation or business rules. 
That might be handled by code in data-entry forms.

I recommend importing raw data and adding keys and indexes afterwards. You may 
well find that adding those rules generates errors. If you get an error it's 
almost certainly because you haven’t understood the data.

That is almost certainly guaranteed not to work for any relational database as 
the relations will not be maintained.
