Build Semantic Layer Views for Azure Table Data in APOS Live Data Gateway

APOS Live Data Gateway (LDG) serves as a data connection and data transformation solution, facilitating live data connectivity and broadening data source possibilities for SAP Analytics Cloud and other SAP solutions. When integrated with CData Connect Cloud, users have the capability to construct semantic layer views for real-time access to Azure Table data, enabling real-time analytics on Azure Table in a manner akin to working with a relational database.

CData Connect Cloud offers a dedicated SQL Server interface for Azure Table, enabling data querying directly from Azure Table without the need to replicate data to a native database. With pre-optimized data processing capabilities, CData Connect Cloud efficiently directs all supported SQL operations, including filters and JOINs, directly to Azure Table. This harnesses server-side processing to swiftly retrieve the requested Azure Table data.

Configure Azure Table Connectivity for APOS Live Data Gateway

Connectivity to Azure Table from APOS Live Data Gateway is made possible through CData Connect Cloud. To work with Azure Table data from APOS Live Data Gateway, we start by creating and configuring a Azure Table connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Azure Table" from the Add Connection panel
3. 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.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Azure Table Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connecting to Azure Table & Creating a Semantic Layer View

After configuring the connection in CData Connect Cloud you are ready to connect to Azure Table in the Live Data Gateway Admin tool and build a semantic layer view in the Live Data Gateway Web UI.

Configuring the Connection to Azure Table

1. Log into your APOS Live Data Gateway Manager
2. If you haven't already, update your APOS LDG license file
   1. Click File -> Configurations
   2. Click on the "..." Menu for the License
   3. Select the license file from the APOS team that includes your CData Connect Cloud license
3. In the APOS Live Data Gateway Manager, click "Add"
4. In the APOS Live Data Gateway On the Connection tab, configure the connection:
   • Set Data Source to "Database"
   • Set Database to "JDBC Generic"
   • Set Connection String to a connection string similar to the following, using the name of the connection you configured earlier, e.g. jdbc:sqlserver://tds.cdata.com:14333;databaseName=AzureTables1
   • Set Driver Class to "com.CData.connect.Driver" (this should be set by default)
5. Click Test Connection
6. Click Save
7. Give your connection a unique prefix (e.g. "azuretables")
8. Highlight the newly created connection and click File -> "Approve Users For Web UI"
9. Approve the appropriate DB users to create views and click "Save"

At this point, we are ready to build our semantic layer view in the Live Data Gateway Web UI.

Creating a Semantic Layer View

1. In your browser, navigate to the APOS Live Data Gateway Portal
2. Select a Connection (e.g. "azuretables")
3. Set User Name and Password to your Connect Cloud username and PAT .
4. Click "Login"
5. Once connected, click "Semantic Layer" to create a new semantic layer view
6. Click "New Semantic Layer View"
7. Set the Semantic Layer View Prefix and Semantic Layer View Name
8. Click "Step 2"
9. Select the table(s) and column(s) you wish to include in your view
10. Click "Step 3"
11. Select the Measures from the available table columns
12. Click "Step 5" (we skipped the "Extra Dimensions" step)
13. Add any Variable Prompts
14. Click "Step 6"
15. Define any Table Joins
16. Click "Review"
17. Review you semantic layer view and click "Save"

With the Semantic Layer View created, you are ready to access your Azure Table data through the APOS Live Data Gateway, enabling real-time data connectivity to Azure Table data from SAP Analytics Cloud and other SAP solutions.
