Analyze Azure Data Catalog Data in Infragistics Reveal
Use the CData API Server to create an OData API on top of Azure Data Catalog data and visualize live Azure Data Catalog data in Ingragistics Reveal.
Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server and Azure Data Catalog ADO.NET Provider to build dynamic dashboards from live Azure Data Catalog data. The CData API Server generates an OData API for Azure Data Catalog, which is natively consumable in Reveal. In this article, we walk through connecting to Azure Data Catalog in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.
Connect to Azure Data Catalog 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 Data Catalog"
- Enter the necessary authentication properties to connect to Azure Data Catalog.
You can optionally set the following to read the different catalog data returned from Azure Data Catalog.
Connect Using OAuth Authentication
You must use OAuth to authenticate with Azure Data Catalog. OAuth requires the authenticating user to interact with Azure Data Catalog using the browser. For more information, refer to the OAuth section in the help documentation.
Add Azure Data Catalog Resource Definitions in API Server
After connecting to Azure Data Catalog, create Resources, which represent API endpoints for Azure Data Catalog data.
- Click Settings -> Resources -> Add Resource
- Select the Azure Data Catalog 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 Data Catalog from Reveal through API Server.
- Click Settings -> Users
- Click Add
- Configure a User with access to the Azure Data Catalog 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 Data Catalog 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
