ADDA is a multipurpose toolkit for designing, creating, and maintaining the database layer throughout the entire application life cycle. Main features include database primary planning, which keeps track of most recent changes; a CASE-like database display; the ability of the end user to add customized tables and columns; instant and automatic database creation; fully automatic upgrading of customers' databases; open file format (XML); reverse-engineered existing databases, which generate SQL creation scripts; the capacity to use a pool of columns for common use to speed up development time; and printing of the data dictionary.

ADDA is an excellent supplement to modern development tools. Not only does it organize database-related meta data, but it also performs the formerly long and tedious process of database upgrading in a single click, eliminating the need for DBA on your site. Given its easy deployment, ADDA is even more effective for large-scale application users.
