Convert JSON to Enumeration Online in https://json2enum.com
Recently I had a task to analyze data from existing system exported in long and complex JSON.
I started looking for a simple service to fetch all values from JSON as an enumeration and surprisingly there was none online.
So I came up with simple client-side page https://json2enum.com that does the job. Enjoy.

Dynamics AX 7 data model vs AX 2012
Hello Axapters,
Last week I spent some time analyzing the differences between AX 7 and AX 2012 R3 CU9 data model, specifically the list of SQL Server tables in both versions.
If you judge by the
numbers only the changes are radical: about 740 out of 6250 AX 2012 tables have
been deleted or renamed and about 600 tables have been added or renamed in AX
7, not including ~1640 new out of the box staging tables.

Dynamics AX web server and client
Application tiers in AX 7
For one thing, AX is no more a WinForms application, it is a website. There
is no "AOS” as such, my friends. Though still a couple of Windows
services run on the server side:
·
Batch management services that “Polls and
executes AX batch requests.”
·
DIXF service that “Executes import/export logic
for the Microsoft Dynamics AX Data Import/Export Framework”.

Dynamics AX 7 Codebase Architecture
It is probably the toughest
topic for developers to grasp and get used to and the most cardinal change for
internal code architecture. The idea as I see it is to make the huge standard codebase modular
and loosely coupled and promote AX architects and developers to do the same
with their code.
Packages, models and dependencies
In AX 2012 and before the
whole application code existed within one namespace split by layers and models.
You could call or reference any code in your Dynamics AX instance from any
other place. We all know the upsides and downsides of this approach.

What's new in Microsoft Dynamics AX 7
Hello and welcome to my
blog, Folks!
So what is new in Microsoft
Dynamics AX 7 for developers and technical consultants comparing to all
previous versions? We’re witnessing without exaggeration the most radical
change in Dynamics AX history inspired by the current technological trends and
proposals from other ERP vendors.This release is mainly technical with some
important functional changes though.
It is tough to pick out the
most important among the numerous changes. Here is my chart of innovations from
the technical point of view. I tried try condense the essence of every change
into a couple of sentences.
- Web client and server. AX 7 is a website, browser is the client. UI metadata is rendered into HTML5, CSS and JavaScript. No X++ code on the client and no EP, of course. No ActiveX and Managed Hosts either.
- .NET integration. X++ and other metadata are stored on disk, compiled into CIL assemblies and executed by the server’s CLR. Development is done in Visual Studio only. Some changes to X++ syntax and model. Support of TFS / VSO integration and automated builds.
- Authorization and Office 365 integration. AX 7 users must have Azure Active Directory account in order to access the application and be authorized using OAuth2.
- Cloud deployment and ALM. Production environment can only be deployed in Azure and may use SQL Azure as DBMS. Non-production environments can be deployed in Azure or on-premise as pre-set VMs provided by Microsoft. Pricing is subscription-based. ALM done through LCS - a new cloud service with a lot of nice tools and methodologies.
- Codebase architecture. The whole codebase, including standard and custom code will be split into packages that are connected with one-way dependencies. You may reference objects only within the same and dependant packages. A new concept of extension - a non-intrusive way of customizations together with event-driven approach form a totally new architecture, customization and deployment ways. Package is compiled into a binary Nuget package for deployment.
- Integration, data management and services. AIF gets replaced by various SOAP, REST and JSON services and DIXF that is based on Data entity - a kind of view used for integration throughout the system. More tight two-ways integration with Office.
- Task recorder. It is difficult to classify it to any other category. Allows to record, document and playback all user actions from browser. A great tool for automated testing and education.
- BI. No more SSAS cubes, instead real-time BI that leverages SQL Server Column Store Index capabilities. Close PowerBI integration. UI-embedded user-adjustable KPIs.
- SSRS Reporting, Workflow, Security. Cosmetic changes.
- The main deprecated features. EP, RoleCenter, .NET connector, SSAS cubes, Virtual companies, ActiveX and Hosted.NET controls, Production builder and WMSII. Some features are not included into the first release but were not declared deprecated.
