ETL Microsoft Teams in Oracle Data Integrator

Leverage existing skills by using the JDBC standard to read and write to Microsoft Teams: Through drop-in integration into ETL tools like Oracle Data Integrator (ODI), the CData JDBC Driver for Microsoft Teams connects real-time Microsoft Teams data to your data warehouse, business intelligence, and Big Data technologies.

JDBC connectivity enables you to work with Microsoft Teams just as you would any other database in ODI. As with an RDBMS, you can use the driver to connect directly to the Microsoft Teams APIs in real time instead of working with flat files.

This article walks through a JDBC-based ETL -- Microsoft Teams to Oracle. After reverse engineering a data model of Microsoft Teams entities, you will create a mapping and select a data loading strategy -- since the driver supports SQL-92, this last step can easily be accomplished by selecting the built-in SQL to SQL Loading Knowledge Module.

Install the Driver

To install the driver, copy the driver JAR and .lic file, located in the installation folder, into the ODI appropriate directory:

• UNIX/Linux without Agent: ~/.odi/oracledi/userlib
• UNIX/Linux with Agent: $ODI_HOME/odi/agent/lib
• Windows without Agent: %APPDATA%\Roaming\odi\oracledi\userlib
• Windows with Agent: %APPDATA%\Roaming\odi\agent\lib

Restart ODI to complete the installation.

Reverse Engineer a Model

Reverse engineering the model retrieves metadata about the driver's relational view of Microsoft Teams data. After reverse engineering, you can query real-time Microsoft Teams data and create mappings based on Microsoft Teams tables.

1. In ODI, connect to your repository and click New -> Model and Topology Objects.
2. On the Model screen of the resulting dialog, enter the following information:
   • Name: Enter MSTeams.
   • Technology: Select Generic SQL (for ODI Version 12.2+, select Microsoft SQL Server).
   • Logical Schema: Enter MSTeams.
   • Context: Select Global.
3. On the Data Server screen of the resulting dialog, enter the following information:
   • Name: Enter MSTeams.
   • Driver List: Select Oracle JDBC Driver.
   • Driver: Enter cdata.jdbc.msteams.MSTeamsDriver
   • URL: Enter the JDBC URL containing the connection string.

     You can connect to MS Teams using the embedded OAuth connectivity. When you connect, the MS Teams OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.msteams.jar

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

     Below is a typical connection string:

     jdbc:msteams:OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH
4. On the Physical Schema screen, enter the following information:
   • Name: Select from the Drop Down menu.
   • Database (Catalog): Enter CData.
   • Owner (Schema): If you select a Schema for Microsoft Teams, enter the Schema selected, otherwise enter MSTeams.
   • Database (Work Catalog): Enter CData.
   • Owner (Work Schema): If you select a Schema for Microsoft Teams, enter the Schema selected, otherwise enter MSTeams.
5. In the opened model click Reverse Engineer to retrieve the metadata for Microsoft Teams tables.

Edit and Save Microsoft Teams Data

After reverse engineering you can now work with Microsoft Teams data in ODI. To edit and save Microsoft Teams data, expand the Models accordion in the Designer navigator, right-click a table, and click Data. Click Refresh to pick up any changes to the data. Click Save Changes when you are finished making changes.

Create an ETL Project

Follow the steps below to create an ETL from Microsoft Teams. You will load Teams entities into the sample data warehouse included in the ODI Getting Started VM.

1. Open SQL Developer and connect to your Oracle database. Right-click the node for your database in the Connections pane and click new SQL Worksheet.

   Alternatively you can use SQLPlus. From a command prompt enter the following:

   sqlplus / as sysdba
2. Enter the following query to create a new target table in the sample data warehouse, which is in the ODI_DEMO schema. The following query defines a few columns that match the Teams table in Microsoft Teams: CREATE TABLE ODI_DEMO.TRG_TEAMS (LOCATION_DISPLAYNAME NUMBER(20,0),subject VARCHAR2(255));
3. In ODI expand the Models accordion in the Designer navigator and double-click the Sales Administration node in the ODI_DEMO folder. The model is opened in the Model Editor.
4. Click Reverse Engineer. The TRG_TEAMS table is added to the model.
5. Right-click the Mappings node in your project and click New Mapping. Enter a name for the mapping and clear the Create Empty Dataset option. The Mapping Editor is displayed.
6. Drag the TRG_TEAMS table from the Sales Administration model onto the mapping.
7. Drag the Teams table from the Microsoft Teams model onto the mapping.
8. Click the source connector point and drag to the target connector point. The Attribute Matching dialog is displayed. For this example, use the default options. The target expressions are then displayed in the properties for the target columns.
9. Open the Physical tab of the Mapping Editor and click TEAMS_AP in TARGET_GROUP.
10. In the TEAMS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

You can then run the mapping to load Microsoft Teams data into Oracle.
