Microsoft Dynamics AX 2009 Architecture overview

Microsoft Dynamics AX 2009 Architecture

With Microsoft Dynamics AX 2009, the full range of functionality is delivered in the first installation. Unused functionality remains hidden until needed and is enabled by entering the appropriate license code into the system. Companies buy appropriate licenses and only pay for modules they use. With Microsoft Dynamics AX 2009, there is no need for integrating and managing multiple systems.
Sophisticated customizations can be made without special IT or programming knowledge. Frequently, this process can cost companies significant time and money because changes must be made to multiple forms and reports. But with the Microsoft Dynamics AX 2009 configuration system, the unused features are hidden, not removed, and the process is simple.

• The standard Microsoft Dynamics AX 2009 application components are stored in the core layer called the system layer which is controlled and maintained by Microsoft Dynamics.
• Country-specific, industry-specific, and customer-specific modifications are created and stored in the layers stacked on top of the core layer.
• The outermost layer is where the individual end user can store personal modifications, for example a report layout.
• Although the top layers can be changed, the standard Microsoft Dynamics AX functionality remains the same and you can return to the original version without running a new installation.

There are ten separate layers in the Microsoft Dynamics AX 2009 application hierarchy. The first four are used by Microsoft Dynamics AX developers:
Layer Description
SYS The standard application is implemented at the lowest level, the SYS layer. This layer includes country/region specific features developed for the United States,Western European and African countries..
GLS The GLS layer includes features developed for allcountries that have not been implemented in the SYS layer.
HFX HFX is the application layer used for on-demand hotfixes. A hotfix is a single code package composed of one or more files used to address a problem in the product.
SL1, SL2, or SL3 A layer where the distributor can implement vertical partner solutions. SL is an abbreviation for SoLution.

There are two layers used by Microsoft Dynamics AX business partners:
Layer Description
BUS When a business partner (BUS) creates a generic solution, the modifications are saved in the BUS layer.
VAR Value Added Resellers (VAR) can make customer-specific modifications to the business partner solution. These are saved in the VAR layer.

There are two layers used by Microsoft Dynamics AX customers:
Layer Description
CUS The supervisor or administrator of an end user installation may want to make modifications generic to the company. Such modifications are typically saved in the Customer (CUS) layer.
USR End users may want to make their own modifications. These modifications are typically saved in the User (USR) layer.



• When partners or users change the application, the modified objects are stored in different files. Therefore, the standard version of Microsoft Dynamics AX 2009 does not change, but the objects will be copied to a higher level in the layer structure from which the modifications will be executed.
• Partners and the customers always have the chance of comparing or even reverting to the standard version before the modification.
