This article shows how to transfer Office 365 data into a data warehouse using Oracle Data Integrator.
Leverage existing skills by using the JDBC standard to read and write to Office 365: Through drop-in integration into ETL tools like Oracle Data Integrator (ODI), the CData JDBC Driver for Office 365 connects real-time Office 365 data to your data warehouse, business intelligence, and Big Data technologies.
JDBC connectivity enables you to work with Office 365 just as you would any other database in ODI. As with an RDBMS, you can use the driver to connect directly to the Office 365 APIs in real time instead of working with flat files.
This article walks through a JDBC-based ETL -- Office 365 to Oracle. After reverse engineering a data model of Office 365 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 (cdata.jdbc.office365.jar) and .lic file (cdata.jdbc.office365.lic), located in the installation folder, into the ODI appropriate directory:
- UNIX/Linux without Agent: ~/.odi/oracledi/userlib
- UNIX/Linux with Agent: ~/.odi/oracledi/userlib and $ODI_HOME/odi/agent/lib
- Windows without Agent: %APPDATA%\Roaming\odi\oracledi\userlib
- Windows with Agent: %APPDATA%\odi\oracledi\userlib and %APPDATA%\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 Office 365 data. After reverse engineering, you can query real-time Office 365 data and create mappings based on Office 365 tables.
- In ODI, connect to your repository and click New -> Model and Topology Objects.
- On the Model screen of the resulting dialog, enter the following information:
- Name: Enter Office365.
- Technology: Select Generic SQL (for ODI Version 12.2+, select Microsoft SQL Server).
- Logical Schema: Enter Office365.
- Context: Select Global.
- On the Data Server screen of the resulting dialog, enter the following information:
- Name: Enter Office365.
- Driver List: Select Oracle JDBC Driver.
- Driver: Enter cdata.jdbc.office365.Office365Driver
- URL: Enter the JDBC URL containing the connection string.
Office 365 uses the OAuth authentication standard. To authenticate requests, you will need to obtain the OAuthClientId, OAuthClientSecret, and OAuthCallbackURL by registering an app with Office 365. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Office 365 JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.office365.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical connection string:
jdbc:office365:OAuthClientId=MyApplicationId;OAuthClientSecret=MyAppKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH
- 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 Office 365, enter the Schema selected, otherwise enter Office365.
- Database (Work Catalog): Enter CData.
- Owner (Work Schema): If you select a Schema for Office 365, enter the Schema selected, otherwise enter Office365.
- In the opened model click Reverse Engineer to retrieve the metadata for Office 365 tables.
Edit and Save Office 365 Data
After reverse engineering you can now work with Office 365 data in ODI. To edit and save Office 365 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 Office 365. You will load Files entities into the sample data warehouse included in the ODI Getting Started VM.
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
- 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 Files table in Office 365:
CREATE TABLE ODI_DEMO.TRG_FILES (SIZE NUMBER(20,0),Name VARCHAR2(255));
- 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.
- Click Reverse Engineer. The TRG_FILES table is added to the model.
- 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.
- Drag the TRG_FILES table from the Sales Administration model onto the mapping.
- Drag the Files table from the Office 365 model onto the mapping.
- 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.
- Open the Physical tab of the Mapping Editor and click FILES_AP in TARGET_GROUP.
- In the FILES_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.
You can then run the mapping to load Office 365 data into Oracle.
