ER/Studio

ER/Studio is data architecture and data modeling software developed by IDERA, Inc. ER/Studio is compatible with multiple database platforms and is used to create and manage database designs, as well as to document and reuse data assets. In 2015, Embarcadero Technologies was acquired by database and infrastructure management software company IDERA, Inc. Since the acquisition by IDERA, Inc., ER/Studio has been renamed to ER/Studio Data Architect with updated features.

Overview

ER/Studio has a computer-aided software engineering tool (or CASE tool). Users can utilize ER/Studio as a way to take conceptual data model and create a logical data model that is not dependent on a specific database technology. This schematic model can be used to create the physical data model. Users can then forward engineer the data definition language required to instantiate the schema for a range of database-management systems. The software includes features to graphically modify the model, including dialog boxes for specifying the number of entity–relationships, database constraints, indexes, and data uniqueness. ER/Studio supports four data modeling languages: IDEF1X, two variants^{[citation needed]} of information technology engineering developed by James Martin, and a form of dimensional modeling notation.
