hmmmm, not gonna lie but you got a few things to learn before completing your goal.
The central concept you need to get familiar with is ADO.NET. It's more of a concept than a language since you can implement it in any .NET language. Using ADO you can move around your various data sources that you want to import and export.
Then you need to learn about connecting to data sources. Connecting to Access isn't too hard, but it could take 30 minutes - 2 hours if you've never done it before. A good place to start is ConnectionStrings.com
Beyond that it's hard to give much more information, your goal is kinda vague. As you learn more, feel free to edit your question to add more information. Code blocks are great.
