Hello,

I have two websites that have an almost identical database schema. the only difference is that some tables in one website have 1 or 2 extra fields that the other and vice versa.

I wanted to the same Database Access layer classes to will manipulate both websites.

What can be a good design pattern that can be used to handle that little difference.

for example, I have a method createAccount(Account account) in my DAO class but the implementation will be slightly different between website A and website B.

I know design patterns don't depend on the language but FYI i m working with Perl.

Thanks
