Validate Amazon Marketplace Data with QuerySurge

QuerySurge is a smart data testing solution that automates data validation and testing. When paired with the CData JDBC Driver for Amazon Marketplace, QuerySurge can work with live Amazon Marketplace data. This article walks through connecting to Amazon Marketplace data from QuerySurge.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Amazon Marketplace data. When you issue complex SQL queries to Amazon Marketplace, the driver pushes supported SQL operations, like filters and aggregations, directly to Amazon Marketplace 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 Amazon Marketplace data using native data types.

Connecting to Amazon Marketplace Data in QuerySurge

To connect to live Amazon Marketplace data from QuerySurge, you need to deploy the JDBC Driver JAR file to your QuerySurge Agent(s) and add a new connection from the QuerySurge Admin view.

Deploy the JDBC Driver

1. Download the CData JDBC Driver for Amazon Marketplace installer, unzip the package, and run the JAR file to install the driver.
2. Once the driver is installed, stop the Agent Service.
3. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for Amazon Marketplace\lib\) to your Agent(s) (QuerySurge_install_dir\agent\jdbc).
4. Restart the Agent Service.

For more information on deploying JDBC drivers for QuerySurge, refer to the QuerySurge Knowledge Base.

Configure a New Connection to Amazon Marketplace

1. Log into QuerySurge and navigate to the Admin view.
2. Click Configuration -> Connections in the Administration Tree.
3. Click Add to create a new connection.
4. In the QuerySurge Connection Wizard, click Next.
5. Name the connection (e.g. CData JDBC Connection to Amazon Marketplace).
6. Set the Data Source to "All Other JDBC Connections (Connection Extensibility)" and click Next.
7. Set the Driver Class to cdata.jdbc.amazonmarketplace.AmazonMarketplaceDriver and click Next.

8. Set the Connection URL using the necessary connection properties to authenticate with Amazon Marketplace. Your Connection URL will look something like the following:

   jdbc:amazonmarketplace:AWS Access Key Id=myAWSAccessKeyId;AWS Secret Key=myAWSSecretKey;MWS Auth Token=myMWSAuthToken;Seller Id=mySellerId;Marketplace=United States;

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.amazonmarketplace.jar

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

   To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

9. Set the Test Query to enable the Test Connection button for the Connection (e.g. SELECT * FROM Orders LIMIT 1) and click Next.
10. Click Test Connection to ensure the connection is configured properly and click Save to add the connection.

Once the connection is added, you can write SQL queries against your Amazon Marketplace data in QuerySurge.

Compare Amazon Marketplace Data Queries with a QueryPair

With the connection configured, you can follow the steps below to compare querying Amazon Marketplace data with a QueryPair.

1. Select "Design Library" from the Design Menu
2. Click QueryPairs under QuerySurge Design
3. Click "Create New QueryPair"
4. Name the QueryPair and click Save
5. In either the Source or Target panes, select the connection created above (select the same connection to query Amazon Marketplace twice or another connection to perform a comparison)
6. Write queries in the Editor for each pane, e.g. SELECT * FROM Orders
7. Click the "Design-Time Run" tab to execute the queries
8. When the query execution is finished, click "View Query Results" to see the Amazon Marketplace data returned by the query
