ETL Smartsheet in Oracle Data Integrator

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

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

This article walks through a JDBC-based ETL -- Smartsheet to Oracle. After reverse engineering a data model of Smartsheet 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 Smartsheet data. After reverse engineering, you can query real-time Smartsheet data and create mappings based on Smartsheet 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 Smartsheet.
   • Technology: Select Generic SQL (for ODI Version 12.2+, select Microsoft SQL Server).
   • Logical Schema: Enter Smartsheet.
   • Context: Select Global.
3. On the Data Server screen of the resulting dialog, enter the following information:
   • Name: Enter Smartsheet.
   • Driver List: Select Oracle JDBC Driver.
   • Driver: Enter cdata.jdbc.smartsheet.SmartsheetDriver
   • URL: Enter the JDBC URL containing the connection string.

     Smartsheet uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.

     However, for testing purposes you can instead use the Personal Access Token you get when you create an application; set this to the OAuthAccessToken connection property.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.smartsheet.jar

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

     Below is a typical connection string:

     jdbc:smartsheet:OAuthClientId=MyOauthClientId;OAuthClientSecret=MyOAuthClientSecret;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 Smartsheet, enter the Schema selected, otherwise enter Smartsheet.
   • Database (Work Catalog): Enter CData.
   • Owner (Work Schema): If you select a Schema for Smartsheet, enter the Schema selected, otherwise enter Smartsheet.
5. In the opened model click Reverse Engineer to retrieve the metadata for Smartsheet tables.

Edit and Save Smartsheet Data

After reverse engineering you can now work with Smartsheet data in ODI. To edit and save Smartsheet 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 Smartsheet. You will load Sheet_Event_Plan_Budget 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 Sheet_Event_Plan_Budget table in Smartsheet: CREATE TABLE ODI_DEMO.TRG_SHEET_EVENT_PLAN_BUDGET (PROGRESS NUMBER(20,0),TaskName 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_SHEET_EVENT_PLAN_BUDGET 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_SHEET_EVENT_PLAN_BUDGET table from the Sales Administration model onto the mapping.
7. Drag the Sheet_Event_Plan_Budget table from the Smartsheet 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 SHEET_EVENT_PLAN_BUDGET_AP in TARGET_GROUP.
10. In the SHEET_EVENT_PLAN_BUDGET_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

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