Intershop applications use relational databases. A relational schema specifies a collection of table definitions, providing structure for the data housed in the database instance. The database structure is tangibly pictured in an entity-relationship diagram. These diagram/model is contained in the attached *.zip files.
The erm_pdf_<version>.zip contains a set of PDF documents.
The erm_pdm_<version>.zip contains a set of physical data models (*.pdm files) usable with Sybase PowerDesigner.
