拆分Access数据库和使用OleDb的概念

I've run into problems with Access database as it's maximum size is limited to 2 GB. I've done a little research and found about split Access databases. When splitting the database, the original file remains and one new is added. I don't quite understand what I'll be getting with this. As I understand, the newly created file is a back-end - the data is stored here, the original file is just a front-end with forms, queries, etc. The limit on back-end file will still remain effective. Am I right? Perhaps multiple splits will do the trick, but I don't understand the concept of it.I've run into problems with Access database as
