EXPRESS Database Tools
The EDMdatabase is Jotne EPM Technology’s proprietary storage technology. It is designed to store and process all information defined in EXPRESS and EXPRESS-X schemas (dictionary data) and Populations thereof (application data). Data are stored as Instances in a Model. A Model is stored in a Repository. 
This new tool facilitates users to create EDMDB and load or delete various EDM-specific schemas and models. This is a common tool which takes care of all such operation specified above. Currently this tool restricts the database context user name to “superuser”.
Using these tools you can:
Create an EDM database or open existing database; see Create EDM Database
Load the EDM database; see Load Schema
Delete EXPRESS/EXPRESS-X mappings; see Delete Schema
Load Model
* 
For information on various mappings and underlying features see the EDMassist website. This is the website of the EXPRESS Data Manager, which is a third-party product that supports STEP.
