I have dabbled in several areas of development, but not enough to be good at any of them. To name a few, I have used MS Access for over 20 years and have developed several databases at the expert level. I have taken courses in C#, SQL, and a few others, which I never learned very well.
I would like to learn how to develop web based front-ends for SQL databases starting from scratch. I know everybody has their own preferences. I do have access to Lynda.com and EDX. Using those, what would be the best courses to start with? Or, if you have other free courses I can use that are better, please let me know.
