Connect to eBay Data in the Denodo Platform

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for eBay, Denodo users can work with live eBay data alongside other enterprise data sources. This article walks through creating a virtual data source for eBay in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live eBay data. When you issue complex SQL queries to eBay, the driver pushes supported SQL operations, like filters and aggregations, directly to eBay and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze eBay data using native data types.

Create the eBay Virtual Port

To connect to live eBay data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

1. Download the CData JDBC Driver for eBay installer, unzip the package, and run the JAR file to install the driver.
2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for eBay\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-ebay-19).
3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
4. Right-click "admin" and select New -> Data source -> JDBC.
5. Configure the JDBC Connection:
   • Name: your choice, e.g.: ebay
   • Database adapter: Generic
   • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-ebay-19
   • Driver class: cdata.jdbc.ebay.EbayDriver

   • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

     jdbc:ebay:AppId=MyAppId;CertId=MyCertId;DevId=MyDevId;SiteId=MySiteId;RuName=MyRuName;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH

     Information on creating the Database URI follows:

     Built-In Connection String Designer

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

     java -jar cdata.jdbc.ebay.jar

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

     If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

     Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

     The user consent flow additionally requires the RuName and CallbackURL.

     See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

6. Click the "Test connection" button to confirm the configuration and click Save.

View eBay Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of eBay data for use in the Denodo Platform.

1. Click the "Create base view" button in the newly created VirtualPort (admin.Ebay).
2. Expand the object tree and select the objects (tables) you wish to import.
3. Click the "Create selected" button to create views of the eBay data.
   Optional: Click "Create associations from foreign keys" to define relationships between the objects.
4. With the view(s) created, navigate to a table (cdata_ebay_itemlisting) in the Server Explorer and double-click the selected table.
5. In the new tab, click "Execution panel" to open a query panel.
6. Customize the query in the "Execute" tab or use the default:

   SELECT * FROM cdata_ebay_itemlisting CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
   

7. Click Execute to view the data.

With the base view created, you can now work with live eBay data like you would any other data source in Denodo Platform, for example, querying eBay in the Denodo Data Catalog.
