Toad Data Modeler

Easy-to-use, cross-platform database modeling software. Easily create high-quality data models. Toad Data Modeler enables you to rapidly deploy accurate changes to data structures across more than 20 different platforms. It allows you to construct logical and physical data models, compare and synchronize models, quickly generate complex SQL/DDL, create and modify database schema and scripts, as well as reverse and forward engineer both databases and data warehouse systems. Toad's database modeling tools simplify design, maintenance and documentation — at a price your organization can afford.

Desktop (VDI)

Problem during print on virtual printer — the problem occurs only in case of print from local machine (all printers from local machine are visible on vWorkspace). If the virtual printer is installed on vWorkspace directly, the problem should not occur.


Oracle VM 3.0

Toad Data Modeler has been tested with VMware Server 2 running on Windows 7.

Toad Data Modeler may work correctly in virtual environments other than the tested ones. In case of virtual servers, support for Toad Data Modeler is provided on the basis of supported operating systems.
