Toad Data Modeler helps organizations create, maintain and document their database systems with an easy-to-use graphical interface into new or existing database structures. Toad Data Modeler enables users to reverse engineer database structures, update models, design and generate SQL, compare models and generate alter scripts, create HTML or RTF reports, in addition to versioning of database designs and creation of to-do lists. Toad Data Modeler 7.1 is a minor release, with enhanced features and functionality. See New in Toad Data Modeler 7.1 and Resolved issues for more information. Toad Data Modeler is released in 32-bit and 64-bit versions. The 64-bit version of the application has a significantly higher memory limit which should resolve several common issues incl. out of memory errors, which occurred when working with complex models. In order to reverse engineer databases that require a client you need a corresponding version of the client, i.e. 32-bit or 64-bit.
