Learning database concepts is sometimes difficult and challenging. Animated Database Courseware (ADbC) is designed to support the teaching of database concepts. It is developed at Kennesaw State University. Areas covered include database design, SQL, transactions and database security. The animations are generic not tailored to any specific product or textbook.
In my opinion the tool offers good examples and covers most of the areas of modern database design. It has a good explanations of topics like transactions Concurrency, store procedure and functions, triggers.
