Need a good tutorial / source about databases

Hello, I'm trying to develop an application which will use complex database. I mean I need to learn to creating and manipulating databases using Visual Basic (2012 or later), especially relationships and its basics. I'm not good at sql but used MS Access before.

Can anyone guide me a book, web page or other things?

Our Database Development FAQs/Tutorials (at the top of the Database Development forum) contains several useful articles that may help you, including some with VB.Net code.

In addition, see links below.

JMC's Retrieving-and-Saving-Data-in-Databases thread
Master-Detail-(Parent-Child)-Data-binding-(-NET-2-0-WinForms)
MSDN Data Walkthrough

You should post this thread on the Database development section of the forum.

Thanks for all replies. I'll check them. By the way, should this post be moved to database section of the forum?

It would be better, so I've moved it there :)
