What is Model and ModelStore in ax 2012

Basic Info:
Models were introduced in Microsoft Dynamics AX to help partners and customers more easily install and maintain multiple solutions side by side in the same layer. This topic introduces the concept of models, and describes how models relate to layers and label files. This topic also describes the model store, which is the part of the Microsoft Dynamics AX database in which models are stored. 


Models:
A model is a set of elements in a given layer. Each layer consists of one or more models. Each layer contains one system-generated model that is specific to that layer. Every element in a layer belongs to only one model. In other words, no element can belong to two models in the same layer, and every element must belong to a model.

A model is permanently associated with the layer that is created in. If you need to move one of your models from one layer to another, you must create a project from the model in the AOT, export the project as an xpo file, create a target model in the desired layer, delete the original model to avoid having to resolve layer conflicts, and import the xpo file to the target model. If you are moving elements between models in the same layer, you can use the Move to model command in the AOT.

ModelStore:

Models are stored in the model store. The model store is the part of the Microsoft Dynamics AX database in which all application elements for Microsoft Dynamics AX are stored. Customizations are also stored in the model store. The model store replaces the Application Object Data (AOD) files that were used in earlier versions of Microsoft Dynamics AX. Models that have been installed in the model store are used at run time.

Note: Models can be exported to files that have the .axmodel extension. These files are called model files. Model files are deployment artifacts. Model files can be signed with strong name signing and Microsoft Authenticode signing.

How to manage Label files with Model:

In Microsoft Dynamics AX 2012, label files, or ALD files, are part of models. A label file must be added to a model before the model can be installed. After a model has been installed, ALD files are pulled from the model store to the local of Application Object Server (AOS) instance when the AOS is started. When the AOS is shut down, the ALD files are pushed back to the model store.

ALD files from earlier versions of Microsoft Dynamics AX are not part of a model file. However, you can import these files into the model store from the Label Files section of the Application Object Tree (AOT). Use the Create from file shortcut command.

Note: The ALD file from an earlier version of Microsoft Dynamics AX must not be located in the application folder of AOS. Otherwise, you cannot import the file.

Working with label files across solutions

It is recommend that you use one label file per solution to simplify installation.

If you find that you require multiple label files, it is recommend that you create a single shared, cross-solution label file and package it as a model file. Then, when you install solutions, you must install two models: the solution itself and the label model.

If you want to ship additional languages, you can add the languages to the solution model, increment the model's version number, and then reimport the model.

What is Window Azure?

Azure is an open and flexible cloud platform that enables you to quickly build, deploy, and manage applications across a global network of datacenters that are managed by Microsoft. Azure enables cloud computing. Cloud computing is the delivery of computing capabilities as a service. Cloud computing makes it easy to access IT resources such as computers, networking, and storage.

You can deploy Microsoft Dynamics AX 2012 R3 on Azure. When you do, you may realize the following benefits:

·       Reduce costs

·       Save time

·       Gain flexibility

Azure offers three types of services:-

·       Software-as-a-Service (SaaS):- You use a web browser to use applications that are hosted in the cloud.

·       Platform-as-a-Service (PaaS):- You don’t manage or control the network servers or operating system.  It allows you to focus on the business logic of applications.

·       Infrastructure-as-a-Service (IaaS):- You have control over your virtual machines and the network configuration, but you don’t have to worry about hardware.

Difference between List, Set, Container and Map

What is the difference between List, Set, Container and Map

Containers:
Containers are dynamic and have no limits. They can contain elements of
almost all data types: Boolean, integer, real, date, string, container,
arrays, tables, and extended data types. However, objects may not be stored
in containers.

Containers in AX are used very often. It’s easy to work with them. But…
data in containers are stored sequentially, and thus retrieved sequentially.
This means that containers provide slower data access if you are working with
_large numbers_ of records. In case of large numbers of records use temporary
tables.

List:
Lists are structures that may contain any number of elements that are
accessed sequentially. Lists may contain values of any X++ type. All the
values in the list must be of __the same__(this is the main difference
between lists and containers) type, given in the creation of the list. The
implementation of lists is such that traversal of the list elements is __very
fast.

Take a look for example at class Dialog addControl() method.
There controls are stored in ctrls List.

Map:
A map is a data type that associates one (key) value with another value [An
analog - a small table in memory with two fields: Keys, Values]. Both the key
and value values may be of any valid X++ type, including objects. The types
of the key and the value are given in the declaration of the map. The
implementation of maps is such that access to the values is _very fast_.

Don’t confuse map X++ types with Map objects in AOT, wich are used for
mapping tables with similar structures of fields

Set:
The functionality of Sets is similar with list.  A Set is just an unordered list of items, while a list of items held by a Map
are indexed via via a key.
Take look at
\Classes\sysLabel\LabelModuleId().

In any case use Search in AOT\Classes or Forms and look how are used
different X++ types in AX.
