[MS_AccessPros] Re: How do I devide the front end and back end?

 

Hi Edgar,

A split database actually makes your database modifications easier. One of the major reasons to use a split database is so that you can make changes to your front end forms, reports, queries and code and save it but your data remains safely untouched in the back end tables. Then you just use or distribute the new front end which will use the unchanged back end.

If you need to make changes in the tables in the back end you can do that and then link or relink the tables to the front end.

Kind Regards,

I actually made a new database instead of making changes to the existing one but there is just too much data to be re entered into the new database. I rather make changes to the existing database and just work around the data without loosing it. That's why I wanted to unsplit it, to make it easier to modify it.
