• Visual Studio Express Editions Can I Create an Access DataBase Without Access?

  I don't own Access and this is for Learning Purposes.... Can I create an Access DataBase with my own Schema(I guess that's the word) with VBE or any Other Way I downloaded Northwind.... Can I change Northwind schema without Access Thanks   Yes. I know you could do it with DAO. I'm not sure about ADO. Since ADO.NET is a little less faciliated in persisting, the USE of ADOX has been recommended to me for things like table creation and storage and I find that it works very well with VB.NET.
