Introduction to Ms Dynamics Layered Architecture.

Microsoft Given a seperate architecture which is more flexible to update and customize the application called as layering.In this architecture we find several layers based on their security and functionality.This looks like the following.


The Assumption behind this architecture is to secure the basic application and also the use of This is,
   • Any user of the Microsoft Dynamics AX 2009 application can
     customize the Microsoft Dynamics AX 2009 application
   • The standard application is never overwritten
   • Deleting an object removes it either in the current layer or the layer
     above if the object exists in a higher layer. Every time an object is
     opened, the system automatically searches for and uses the object
     files needed in the highest layers first

Each layer is saved in a separate file that has an extension of .aod. For example,
Axsys.aod is the SYS layer. The aod extension is an acronym for Application
Object Data file.
The layers are designed for different Microsoft Dynamics AX 2009 developer
groups. Three groups have an interest in adding or modifying application objects:
        • Microsoft Business Solution Developers who create the
          standard application
       • Business partners and developers who want to enhance Microsoft
         Dynamics AX 2009
      • Microsoft Dynamics AX 2009 end-users
