Database Illustrator® Program

What is it?

Database Illustrator® (DBI) is a unique tool which automatically produces clearly arranged entity-relationship diagrams for part or all of your database. It facilitates communication between application managers, programmers, designers and database administrators by making diagrams extremely easy to produce, allowing them to be used in design reviews, pre-code walkthroughs, enhancement request analysis, index planning, and throughout the application development and maintenance lifecycle. It also makes an excellent data model browser providing online documentation of your database for use by programmers and analysts.
