Data Bases in Ax 2012 R3

Data Bases in Ax

1. Transaction DataBase
2. Model Store
3. BaseLine Model Store

There are three database components: the Microsoft Dynamics AX transaction database, the model store, and the baseline model store.

• The Application Object Server (AOS) connects to the Microsoft Dynamics AX database to process transactions. 
• The AOS connects to the model store to display forms and reports. 
• The baseline model store is used to upgrade X++ code to Microsoft Dynamics AX 2012, and to analyze application updates before they are applied.

In Microsoft Dynamics AX 2012 R3 and Microsoft Dynamics AX 2012 R2, the model store and the transaction data are stored in separate databases. 

In earlier versions of Microsoft Dynamics AX 2012, the model store and transaction data are stored in a single database.
