ETL Suadeo in Oracle Data Integrator

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

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

This article covers a JDBC-based ETL -- Suadeo to Oracle. After reverse engineering a data model of Suadeo 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.suadeo.jar) and .lic file (cdata.jdbc.suadeo.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 Suadeo data. After reverse engineering, you can query real-time Suadeo data and create mappings based on Suadeo tables.

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

     The driver uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant to authenticate to Suadeo. Authentication occurs directly using your credentials; there is no browser-based authorization flow or refresh token.

     Set the following connection properties:

     • URL: The base URL of your Suadeo instance.
     • User: Your Suadeo username.
     • Password: Your Suadeo password.
     • AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

     When you connect, the driver sends your credentials to the Suadeo OAuth token endpoint, receives an access token, and uses it for all subsequent requests. A new access token is obtained automatically when needed during the session.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.suadeo.jar
     

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

     Below is a typical connection string:

     jdbc:suadeo:URL=https://mysuadeoinstance;User=username;Password=password;AuthenticationName=your_auth_name;
     

   👁 Configuring the Data Server
   
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 Suadeo, enter the Schema selected, otherwise enter Suadeo.
   • Database (Work Catalog): Enter CData.
   • Owner (Work Schema): If you select a Schema for Suadeo, enter the Schema selected, otherwise enter Suadeo.

5. In the opened model click Reverse Engineer to retrieve the metadata for Suadeo tables. 👁 Reverse Engineer the Model
   

Edit and Save Suadeo Data

After reverse engineering you can now work with Suadeo data in ODI. To view Suadeo data, expand the Models accordion in the Designer navigator, right-click a table, and click View data. 👁 Viewing the data.

Create an ETL Project

Follow the steps below to create an ETL from Suadeo. You will load Customers 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 Customers table in Suadeo:

   CREATE TABLE ODI_DEMO.TRG_CUSTOMERS (NAME NUMBER(20,0),Id 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_CUSTOMERS 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_CUSTOMERS table from the Sales Administration model onto the mapping.
7. Drag the Customers table from the Suadeo 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 CUSTOMERS_AP in TARGET_GROUP.
10. In the CUSTOMERS_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab. 👁 SQL-based access to Suadeo enables you to use standard database-to-database knowledge modules.
    

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