Reddit reviews Access 2016 Bible

Well; honestly; good luck.

Powerpivot / Power BI is a pretty new thing; it's undergone so much change in the last 2-3 years; I strongly doubt you'll find much as far as decent resources.

For Access:
http://www.crwsystems.mb.ca/ MIGHT be willing to recommend someone;

If you honestly expect you can learn Access in an hour; just grab a decent book on whatever version you are stuck using; and go from there:

To relate my experience with books written for specifically for MS Access, I will caution that the books are heavily geared towards without within other MS applications, and you typically only need about half of the book to build a working application.

Also, the Access-specific books tend you leave you hanging when it comes to VBA (Visual Basic for Applications) scripting. VBA isn't a necessity, but it does have the potential to add some niceties when it comes to working with forms. Fortunately, most "cookbook" style VBA code is widely available on the internet.

That being said, I learned a lot from the Access 2016 Bible when I was teaching myself last year. I have a copy of the MS Access For Dummies for a previous version, but the reviews of the 2016 version aren't looking too good. Once again, with the plethora of information on the web, you can probably get away with not using a book at all, so it's more a matter of preference. And reading the other comments, I'm going to add another for Django up there...
