Visual Paradigm DB Visual Architect is a Database design tool that provides ORM support that realizes UML design to relational database implementation. Just draw a Class Diagram for the system, and you can generate the required database tables and persistent source code for database manipulation. If you are already maintaining software that accesses relational database, you don't need to start everything from scratch. Just follow a step-by-step wizard and the tool will generate the necessary source code for manipulating the target database in an object-oriented approach.
DBVA Features:
+Round-trip engineering between model and Java source code
+Database generation - generate database tables from ERDs and Class Diagrams
+Multiple database support - work with various DBMS (MYSQL, Oracle, HSQLDB,MS SQL, Sybase...) with the same set of persistent objects
+ORM support - generate the persistent Java objects for manipulating database
+EJB Diagram - Provided to visualize EJB systems.
+EJB Code Generation and Deployment - Generate beans for your application development and deployment.
+Customizable SQL - Override the SQL statements (insert, update and delete) generated by the tool.
+One Class to Multiple Tables Mapping - Maps one class to multiple tables, ideal system design and implementation
+Reverse database to ERD/Class Diagram
+Reverse engineering - reverse XML, XML schema, database tables through JDBC, Java source/class, Hibernate format, .NET dll or exe files, C++ source, CORBA IDL source, Ada9x source into Class models
+Integration with Visio - model domain-specific system by using Visio stencil
+Automatic diagram layout - rearrange shapes and connectors in elegant styles
