Microsoft Dynamics AX Database

The Microsoft Dynamics AX Database

The database is a SQL Server database containing transaction and reference data. This database is functionally equivalent to the principal database in earlier releases of Microsoft Dynamics AX.

The Model Store

The model store is a SQL Server database where all Microsoft Dynamics AX application elements are stored, including customizations. Layer and model information are integral parts of the store. The AOS has access to the model store, handles layer-flattening, and provides model data to all the Microsoft Dynamics AX sub-systems, such as form- and report-rendering and X++ code.
The model store replaces the AOD files used in previous versions of Microsoft Dynamics AX.

Other Databases

The Enterprise Portal requires SharePoint content and configuration databases. SQL Server report server requires a SSRS database. Support for OLAP cubes requires a SSAS database.
