Web Services to using from data access?

two   web services to involve in data access?
a.      REST endpoint
The REST endpoint provides a ‘RESTful’ web service using OData to provide a programming environment.It is the recommended web service to use for tasks that involve creating, retrieving, updating and deleting records.
b.      SOAP endpoint
The SOAP endpoint provides access to all the messages defined in the Organization service. However, only the types defined within the WSDL will be returned.

Many to Many Relationship in Dynamics CRM 2011.

Image
I get asked about many-to-many (a.k.a. N:N) relationships more than just about any other single topic, so here’s a summary of how they work in Dynamics CRM 2011. I’ll review both “native” and “manual” N:N’s, using a simple Association to Contact relationship to illustrate. This is a classic many-to-many: each association should be able to have multiple contacts associated with it, and each contact should in turn be able to be associated with many associations. Native N:N Relationships With native N:N relationships, you open up an entity for customization, click the N:N relationships link, and click the  New Many to Many Relationship  button and select the entity to create the relationship to. For the Association to Contact N:N relationship, I’ll start from the Association entity: In the previous figure, notice that Do no Display is selected in the Display Option for each side. I only show that to illustrate a point: what this will do is prevent the relationship from being displ

When to use plug-ins vs. workflow?

As a developer who is interested in extending or customizing Microsoft Dynamics CRM, you can choose from several methods to perform your tasks. In addition to adding client-side JavaScript code to a form or adding custom ASP.NET pages, you can write a plug-in or create a custom workflow by using the web interface that calls a custom workflow activity. How do you decide when to use a plug-in and when to use a workflow? The technology that you use depends on the task that you have to perform and who will author the customization. For example, you must use a synchronous plug-in real-time workflow if you want to execute custom code immediately before or after the core platform operation executes and before the result of the operation is returned from the platform. You cannot use an asynchronous workflow or asynchronous plug-in in this situation because they are queued to execute after the core operation finishes executing. Therefore, you cannot predict when they will run. If you wan

Required Software and Assemblies To develop Windows Workflow Foundation 4 custom activities, you must develop them on Microsoft .NET Framework 4. If you plan to register your custom workflow activities with Microsoft Dynamics CRM Online, you must build them using the Microsoft .NET Framework 4  PU3  (platform update 3) or a later version, such as .NET 4.5. The following assemblies must be added as references in your project. They can be found in the  SDK\Bin  folder in Microsoft Dynamics CRM SDK. Microsoft.Xrm.Sdk.dll Microsoft.Xrm.Sdk.Workflow.dll Use the CodeActivity Workflow Base Class To create a custom workflow activity, create a class that inherits from the  CodeActivity  workflow base class. This class is available in the  System.Activities namespace. Activities that inherit from the  CodeActivity  class can override the  Execute  method to produce custom functionality. To create a custom activity that inherits from CodeActivity Start Microsoft Visual Stud
