Import from Database

With this ERD creation tool, you may import the tables with their relationships from MS SQL, MySQL or any other database which provides OLE DB provider (e.g. Oracle). This E-R diagramming software not only supports the import of new SQL tables, but it may also import the changes. You may choose which tables you wish to add or update and whether you want to generate a diagram or only import tables to the model.

Script Generation

SQL DDL script generation is a must for a good SQL designer and Software Ideas Modeler is no exception. It allows you to generate database schema scripts and insert scripts for the defined enumerations. Using it with the change tracking feature, you may also generate change scripts.

Enumerations and Codebooks

Each table in a diagram may contain data directly in the model. This is useful, especially for enumerations and codebooks. Software Ideas Modeler is a powerful SQL table creator as it allows you to generate table schema as well as its content.

ER Diagram Editor

The ER diagram editor in Software Ideas Modeler provides many useful features that help you to design entity-relationship diagrams easily.
