Connect to Outlook Data in the Denodo Platform

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData API Driver for JDBC, Denodo users can work with live Outlook data alongside other enterprise data sources. This article explains how to create a virtual data source for Outlook in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Outlook data. When you issue complex SQL queries to Outlook, the driver pushes supported SQL operations, like filters and aggregations, directly to Outlook and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Outlook data using native data types.

Create the Outlook Virtual Port

To connect to live Outlook data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

1. Download the CData API Driver for JDBC installer, unzip the package, and run the JAR file to install the driver.
2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData API Driver for JDBC\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-api-19).
3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
4. Right-click "admin" and select New -> Data source -> JDBC.
5. Configure the JDBC Connection:
   • Name: your choice, e.g.: api
   • Database adapter: Generic
   • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-api-19
   • Driver class: cdata.jdbc.api.APIDriver

   • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

     jdbc:api:Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;

     

     Information on creating the Database URI follows:

     Built-In Connection String Designer

     For assistance in constructing the JDBC URL, use the connection string designer built into the Outlook JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

     	java -jar cdata.jdbc.api.jar
     	

     Fill in the connection properties and copy the connection string to the clipboard.

     Using OAuth Authentication

     Microsoft Graph API uses OAuth 2.0 for authentication. You must register an application in the Microsoft Azure Portal to obtain OAuth credentials (Client ID and Client Secret).

     Obtaining OAuth Credentials

     1. Log in to the Azure Portal.
     2. Navigate to Azure Active Directory > App registrations.
     3. Click New registration to create a new application.
     4. Enter an application name and select the appropriate account types.
     5. Set the Redirect URI to your application's callback URL (e.g., http://localhost:33333 for desktop apps).
     6. Click Register to create the application.
     7. On the application overview page, copy the Application (client) ID - this is your OAuthClientId.
     8. Navigate to Certificates & secrets and create a new client secret.
     9. Copy the client secret value - this is your OAuthClientSecret.
     10. Navigate to API permissions and add the required Microsoft Graph API permissions:
         • Mail.Read - For accessing email messages
         • Contacts.Read - For accessing contacts
         • Calendars.Read - For accessing calendar events
         • Tasks.Read - For accessing To Do tasks
         • offline_access - For obtaining refresh tokens
     11. Click Grant admin consent to grant these permissions.

     Connecting with OAuth

     After setting the following connection properties, you are ready to connect:

     • AuthScheme: Set this to OAuth.
     • InitiateOAuth: Set this to GETANDREFRESH. The CData API Profile for Outlook will automatically walk through the OAuth process in order to obtain the access token.
     • OAuthClientId: Set this to the Application (client) ID from Azure Portal.
     • OAuthClientSecret: Set this to the client secret value from Azure Portal.
     • TenantId: Set this to your Azure AD tenant identifier (GUID or domain name like 'contoso.onmicrosoft.com').
     • CallbackURL: Set this to the Redirect URI you specified in your app registration (e.g., http://localhost:33333 for desktop apps).

     Example connection string

     Profile=C:\profiles\Outlook.apip;AuthScheme=OAuth;InitiateOAuth=GETANDREFRESH;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;TenantId=your_tenant_id;CallbackUrl=http://localhost:33333;
     

     
6. Click the "Test connection" button to confirm the configuration and click Save.

View Outlook Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of Outlook data for use in the Denodo Platform.

1. Click the "Create base view" button in the newly created VirtualPort (admin.API).
2. Expand the object tree and select the objects (tables) you wish to import.
3. Click the "Create selected" button to create views of the Outlook data.
   Optional: Click "Create associations from foreign keys" to define relationships between the objects.
4. With the view(s) created, navigate to a table (cdata_api_calendargroupcalendars) in the Server Explorer and double-click the selected table.
5. In the new tab, click "Execution panel" to open a query panel.
6. Customize the query in the "Execute" tab or use the default:

   SELECT * FROM cdata_api_calendargroupcalendars CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
   

   
7. Click Execute to view the data.

With the base view created, you can now work with live Outlook data like you would any other data source in Denodo Platform, for example, querying Outlook in the Denodo Data Catalog.
