ETL BambooHR in Oracle Data Integrator



This article shows how to transfer BambooHR data into a data warehouse using Oracle Data Integrator.

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

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

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

      Start by setting the Profile connection property to the location of the BambooHR Profile on disk (e.g. C:\profiles\bamboohr.apip). Next, set the ProfileSettings connection property to the connection string for BambooHR (see below).

      BambooHR API Profile Settings

      In order to authenticate to BambooHR, you'll need to provide your API Key. To generate an API key, log in and click your name in the upper right-hand corner of any page to get to the user context menu. If you have sufficient permissions, there will be an "API Keys" option in that menu to go to the page, where you can create a new API Key. Additionally, you will need to set the Domain, found in the domain name of your BambooHR account. For example if your BambooHR account is acmeinc.bamboohr.com, then the Domain should be 'acmeinc'. Set both the API Key and Domain in the ProfileSettings property to connect.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.api.jar

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

      Below is a typical connection string:

      jdbc:api:Profile=C:\profiles\BambooHR.apip;ProfileSettings='Domain=acmeinc;APIKey=your_api_key';
  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 BambooHR, enter the Schema selected, otherwise enter API.
    • Database (Work Catalog): Enter CData.
    • Owner (Work Schema): If you select a Schema for BambooHR, enter the Schema selected, otherwise enter API.
  5. In the opened model click Reverse Engineer to retrieve the metadata for BambooHR tables.

Edit and Save BambooHR Data

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

Create an ETL Project

Follow the steps below to create an ETL from BambooHR. You will load Employees 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 Employees table in BambooHR: CREATE TABLE ODI_DEMO.TRG_EMPLOYEES (DISPLAYNAME 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_EMPLOYEES 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_EMPLOYEES table from the Sales Administration model onto the mapping.
  7. Drag the Employees table from the BambooHR 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 EMPLOYEES_AP in TARGET_GROUP.
  10. In the EMPLOYEES_AP properties, select LKM SQL to SQL (Built-In) on the Loading Knowledge Module tab.

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