DIVA is a software tool that provides a visual analysis of the physical structure of databases. It offers different viewing options (2D, 2.5D, 3D) and helps users to grasp relationships between tables with ease.

When creating complex SQL queries, developers need to continuously look up database structure schemas to oversee foreign-key dependencies, table and field names, and field properties. However, current tools and methods often poorly support all these micro-tasks. It is often not possible to obtain an accurate drawing of a relation's scheme, or they are too large to navigate effectively. In such cases, DIVA can give users a significant performance boost. Developers can quickly and easily overview the entire field of relations in 3D mode, find needed relations in 2.5D mode, and comfortably explore tables and relations in 2D. This type of demonstration provides better memorization of the structure.
When developers face problems in the structure design of databases, a quick and easy understanding of every part of the database structure is needed. Using DIVA provides this analysis quicker and simpler. DIVA is also valuable when developers need to integrate one database subsystem with another and make proper connections between tables in different subsystems.
Moreover, DIVA can be used as an interactive illustration for the database structure, which can be effectively used in meetings, presentations, or brainstorming sessions. The DIVA interface is playful and fun to work with, which makes it easier to turn boring work into creative and enjoyable work.
Version 1.1: Updated relation analyzer, "View deep tables in 2D" feature, fixed wrong default 2D diagram position, added toggle full screen (by Alt+Enter), added table amount counter.
