Introduction To Dynamics AX 2012 Application Object Server

For starters in dynamics AX it’s really important to know where the main development structure lies i.e. AOS. In Microsoft Dynamics AX, there is a 3-tier infrastructure with a database server, an application object server (AOS), and a client. The database server contains the table data. The AOS is used to execute application objects, such as queries and classes. Application objects in the user interface, such as forms and reports, run on the client computer. 

Now let’s look into how we can open and use AOS. On Microsoft Dynamics AX press [Ctrl] + D to open AOS. When AOS open a window is displayed showing Application Object Tree (AOT). This is basically the core unit from where you can go through your table or existing table, change schema, change classes, create or change forms and lots of more.

Fig 1 shows a top level view of the AOT, here you can view all the components. For example Data Dictionary contains all the table, data types, views, enums etc. Parts contain all the info parts and form parts.
