Database ERD- design tool with Reverse Engineering
Design/Reverse Engineer/Generate Scripts/Compare Versions of all major databases with "Apricot DB" ERD- tool
"Apricot DB" is a database tool for design and analysis of the relational database structure. It represents the DB- structure in the form of editable Entity/Relationship Diagrams (ERD). "Apricot DB" allows to perform reverse engineering on the existing database, as well as to create a new database structure from scratch. Allows to generate the essential DDL- scripts for CREATE/DROP/DELETE- operations based on the current ERD.
"Apricot DB" supports two popular ERD notations: the "Crow's Foot" and "IDEF1x".

SchemaSpy analyzes database metadata to reverse engineer dynamic EntityRelationship (ER) diagrams. It works with just about any JDBC-compliant database (Oracle/MySQL/DB2/SQL Server/PostgreSQL/Sybase/etc) and can identify Ruby on Rails relationships.
This framework allows the definition of attributes, entities and relations as used in entity-relationship (ER) models. It will then handle input and representation of data appropriately.
