This document discusses key concepts in the Microsoft Dynamics AX 2009 data dictionary including MorphX, the Application Object Tree (AOT), opening the AOT, tables, data types, extended data types, base enumerations, and views. The AOT is a tree view of all application objects that allows developers to design objects like tables, forms and reports. Tables store company data and transactions, and have fields, indexes, and relations that define them. Data types include primitive types like strings and integers as well as extended types that can inherit properties. Base enumerations provide predefined values for enum fields, and views are virtual tables that retrieve specified data.

2. MorphX
• MorphX is an IDE in Microsoft Dynamics AX
that allows developers to graphically design
data types, base enumerations, tables,
queries, forms, menus and reports.
• In addition to design of application objects, it
also allows access to any application code by
launching the X++ code editor.

3. Application Object Tree
• The Application Object Tree (AOT) is a tree
view of all application objects in Microsoft
Dynamics AX 2009.
• Each branch node contains a different
application object type.

4. Application Object Tree
• Developer can create or modify Microsoft
Dynamics AX 2009 application objects using
drag-and-drop functionality.
• This chapter focuses on those objects
contained in the Data Dictionary node.

5. Opening the AOT
• Access the AOT from the Microsoft Dynamics
AX 2009 application. There are three different
ways to open the AOT.

6. Opening the AOT
• #1: Navigate to FILE MENU > OPEN >
APPLICATION OBJECT TREE.

7. Opening the AOT
• #2: Click the AOT icon on the application
toolbar.
• #3: Press CTRL + D.

8. Tables
• Tables are at the core of the Microsoft
Dynamics AX 2009 application and enable
storing a company's information and
transactions.
• Tables storing data about company
transactions, inventory, general ledger,
journals and more.

9. Creating a Table
• Right-click the
Tables node in
the Data
Dictionary in the
AOT and select
New Table.

10. Tables
• These are referred to as base tables or
application tables. Some frequently used base
tables are shown as follows.

11. Tables
• Tables in Microsoft Dynamics AX 2009 contain
multiple elements that define the table. There
are six categories that define tables:

12. Tables
• Fields
• Field Groups
• Indexes
• Relations
• Delete Actions
• Methods

13. Data Types – Primitive and Extended
• Microsoft Dynamics AX 2009 has built in
primitive and extended data types associated
with the information in the database.
• The primitive data types enabled within
Microsoft Dynamics AX 2009 are:

14. Primitive Data Types
• String
• Integer
• Real
• Date
• Time
• UTCDateTime
• Enum
• Container
• GUID
• Int64
• Boolean

15. Extended Data Types
• Extended Data types can inherit either from
primitive data types or other Extended Data
Types, which enables properties to be
inherited.
• The properties of many fields can change at
one time by changing the properties on the
EDT.

16. Extended Data Types
• Some important facts about Extended Data
Types are in the following list:

17. Extended Data Types
• Extended Data Types can be based on
primitive MorphX data types or on another
EDT.
• If it is possible, custom tables have fields
based on Extended Data Types.
• A relation can be assigned to an Extended
Data Type and it can be made a Related Field
Fixed relation.

18. Extended Data Types
• Most fields in Microsoft Dynamics AX 2009
tables are based on Extended Data Types.
After it is created it can be reused as many
times as it is needed in the application.

19. Base Enumerations (Base Enums)
• Base enumerations are used as data lists for
fields of the Enum type. Base enumerations,
also named Base Enums, are used for
assignment to Enum primitive data type fields
that require a set of predefined values.

20. Views
• A Microsoft Dynamics AX 2009 view is a
virtual table that provides the data records
and fields that are specified by a query. The
following sections describe views and how
they retrieve data.
