    PostgreSQL Database Modeler
    ** ATTENTION ** THIS PROJECT HAS MOVED TO: https://github.com/pgmodeler/pgmodeler New releases only will be available on GitHub. PostgreSQL Database Modeler, or simply pgModeler is an open source project of a CASE tool for modeling PostgreSQL that merges the classical concepts of modeling using entity-relationship diagrams with specific features that only PostgreSQL implements. The pgModeler translates the models created by the user to SQL code and apply them onto database clusters from version 8.0 to 9.1. Please, let me know how the pgModeler is working on your computer! Help to improve this project, give your feedback about the software or report any bug at "Tickets" page. Do not forget to detail the bug and if possible attach a screenshot or model database which expressed the bug. Follow the pgModeler profile on Facebook/Twitter and be up-to-date with new features, fixes and releases. https://www.facebook.com/pgmodeler https://twitter.com/pgmodeler
