ETL QuickBooks in Oracle Data Integrator

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

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

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

     When you are connecting to a local QuickBooks instance, you do not need to set any connection properties.

     Requests are made to QuickBooks through the Remote Connector. The Remote Connector runs on the same machine as QuickBooks and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

     The first time you connect, you will need to authorize the Remote Connector with QuickBooks. See the "Getting Started" chapter of the help documentation for a guide.

     Built-in Connection String Designer

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

     java -jar cdata.jdbc.quickbooks.jar

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

     Below is a typical connection string:

     jdbc:quickbooks:URL=http://remotehost:8166;User=admin;Password=admin123;
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 QuickBooks, enter the Schema selected, otherwise enter QuickBooks.
   • Database (Work Catalog): Enter CData.
   • Owner (Work Schema): If you select a Schema for QuickBooks, enter the Schema selected, otherwise enter QuickBooks.
5. In the opened model click Reverse Engineer to retrieve the metadata for QuickBooks tables.

Edit and Save QuickBooks Data

After reverse engineering you can now work with QuickBooks data in ODI. To edit and save QuickBooks 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 QuickBooks. 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 QuickBooks: CREATE TABLE ODI_DEMO.TRG_CUSTOMERS (CUSTOMERBALANCE NUMBER(20,0),Name 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 QuickBooks 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.

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