Analyze Azure Table Data in Infragistics Reveal
Use the CData API Server to create an OData API on top of Azure Table data and visualize live Azure Table data in Ingragistics Reveal.
Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server and Azure Table ADO.NET Provider to build dynamic dashboards from live Azure Table data. The CData API Server generates an OData API for Azure Table, which is natively consumable in Reveal. In this article, we walk through connecting to Azure Table in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.
Connect to Azure Table from API Server
CData API Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open API Server and click Settings -> Connection -> Add Connection
- Select "Azure Table"
- Enter the necessary authentication properties to connect to Azure Table.
Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.
Add Azure Table Resource Definitions in API Server
After connecting to Azure Table, create Resources, which represent API endpoints for Azure Table data.
- Click Settings -> Resources -> Add Resource
- Select the Azure Table connection
- Select the table you wish to retrieve and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
Add an API Server User
Create a User to connect to Azure Table from Reveal through API Server.
- Click Settings -> Users
- Click Add
- Configure a User with access to the Azure Table Connection and Resource(s)
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple different domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in Settings -> Server.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Create a Dashboard in Reveal
With the API Server configured, we can visualize Azure Table data in Reveal.
- Log into Reveal and click Dashboards -> New
- Click Data Source -> OData Feed
- Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc
- Select Generic Credentials and specify the API Server username and authentication token
- Select the entity you wish to visualize
- Select fields and choose a chart type
