A web application is an application that is accessed over a network such as the Internet or an intranet.
A database web application is an application that is accessed through the internet and queries data from a relational database such as MySQL.
Web applications are popular since web browsers exist on all modern computers.

Common dbweb applications include webmail, online retail sales, online auctions, wikis, and social networking sites.
