    Data Modeler

    Data Modeler

    A tool for creating data models and databases for Microsoft SQL Server

    Welcome to the page for "Data Modeler"; a free tool to create Microsoft SQL Server databases. If you use Microsoft SQL Server and are in search of a clean and intuitive (and free!) data modeler, search no further. With object-level DDL previews, schema support, real-time model validation and DDL regeneration, sub-models, bulk undo/redo, drag 'n' drop foreign key creation, a data dictionary, update/delete foreign key automation, and customizable fonts and colors, this data modeler is an indispensable tool in any DBAs toolbox. I've used a lot of data modelers, from open-source free software to expensive modelers like Embarcadero ER/Studio. None of them come close for me in terms of ease-of-use and productivity gains. select * from DataModelers where Indispensable='true'; (1 row(s) affected) Facebook https://www.facebook.com/DataModelerTool/
