DBDesigner & mdash; is a visual database design tool that allows you to see and manage all the relationships between tables. This is not a simple graphical editor to illustrate the relationship, it is a full-fledged tool for database management in a visual style, supporting MySQL, SQLite, Oracle and MSSQL.
If you describe the database in simple words — it is just a set of structured data with internal connections and the larger its size, the more and more complicated its internal architecture can be, and the more difficult to deal with it without a visual representation. DBDesigner can be of great help in this regard. The interface of the program is very similar to the programs for work with cognitive cards (mind-map): tables look like separate blocks, records of which are connected by lines with arrows (indicating the type of connection) with other tables or blocks. It is also possible to carry out reverse engineering to study the structures of ready-made databases.
Despite the fact that the program is still running, its latest version was released a long time ago, the nearest modern analogue of — MySQL Workbench.
