Connect Tabular SSAS to ASP.NET MVC

Question

I am not finding any relevant article on connecting SSAs tabular model with ASP.NET MVC. Could someone help?

Hi @Manoj Shanmugasundaram ,
First,you need to create the Entity Framework Model.Follow the steps below to save connection properties and map tables to entities in the data model:

1.Create a new MVC project in Visual Studio. In this example, the project name is MvcSSASApp.
If you are using Entity Framework 6, you will need to take the preliminary step of registering the SQL Analysis Services Entity Framework provider for your project.

2.the "LINQ and Entity Framework" chapter in the help documentation for a guide.
Note that MVC 3 scaffolding and MVC 4 scaffolding do not support Entity Framework You can use your scaffolding with Entity Framework 6 by upgrading to the latest version of MVC.

3.To add the .edmx file from the designer, right-click your Models folder and click Add New Item. Select ADO.NET Entity Data Model, name the model, and click Add. In this example, the name of the model is SSASModel.

4.In the Entity Data Model wizard, select the option 'EF Designer from database'. The Entity Data Model wizard is displayed.

5.Click New Connection. Select CData SQL Analysis Services Data Source in the dialog that is displayed.

6.Specify the required connection string properties.
To connect, provide authentication and set the Url property to a valid SQL Server Analysis Services endpoint. You can connect to SQL Server Analysis Services instances hosted over HTTP with XMLA access.
To secure connections and authenticate, set the corresponding connection properties, below. The data provider supports the major authentication schemes, including HTTP and Windows, as well as SSL/TLS.

• HTTP Authentication Set AuthScheme to "Basic" or "Digest" and set User and Password. Specify other authentication values in CustomHeaders.
• Windows (NTLM) Set the Windows User and Password and set AuthScheme to "NTLM".
• Kerberos and Kerberos Delegation To authenticate with Kerberos, set AuthScheme to NEGOTIATE. To use Kerberos delegation, set AuthScheme to KERBEROSDELEGATION. If needed, provide the User,
  Password, and KerberosSPN. By default, the data provider attempts to communicate with the SPN at the specified Url.
• SSL/TLS: By default, the data provider attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.

You can then access any cube as a relational table: When you connect the data provider retrieves SSAS metadata and dynamically updates the table schemas. Instead of
retrieving metadata every connection, you can set the CacheLocation property to automatically cache to a simple file-based store.

A typical connection string is below:

User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;  

7.Name the connection and select whether to include sensitive information, such as connection credentials, in the connection string. For simplicity, this example saves sensitive information in Web.config. The connection settings are saved as SSASEntities.
8.Select the views you need. In this example, Adventure_Works is imported. Also, the option to pluralize object names is deselected in this example. Click Finish to create the .edmx file.
9.Build your project to complete this step.

Scaffold the Controller and Views

After creating the model and building the project, you can use ASP.NET Scaffolding wizards to create the controller and the views.

1. In Solution Explorer, right-click the controllers folder and click Add -> Controller. Select MVC 5 Controller with views, using Entity Framework.
2. In the Add Controller dialog that is then displayed, select the following options:
   • Model class: Select a table you imported; for example, Adventure_Works.
   • Data context class: Select your context class.
3. Leave the default values for the other fields.

You can now access the list of Adventure_Works records at http://MySite/Adventure_Works. With every state change the site picks up any data changes.

Best regards,
Yijing Sun
