DTM Data Modeler is a CASE tool for database developers that supports both forward and reverse engineering. It is an easy-to-use tool allowing you to work both with logical and physical data models in the form of an entity-relationship diagram. The product is intended for database architects and developers and works with data sources via the ODBC interface, which means compatibility with all modern DBMS. Along with basic model properties (sets of entities and relationships between them), the program allows you to create indexes and triggers on the physical level corresponding to the tables of the database that is modeled. The foreign key migration feature makes schema development easier and more visual and also reduces the probability of errors in the integrity of the model. The program can create database schema objects directly in the database as well as create SQL scripts corresponding to the model and taking into account the settings specified by the user.
