Build a PostgreSQL Interface for Adobe Target Data using the CData JDBC Driver

There are a vast number of PostgreSQL clients available on the Internet. From standard Drivers to BI and Analytics tools, PostgreSQL is a popular interface for data access. Using our JDBC Drivers, you can now create PostgreSQL entry-points that you can connect to from any standard client.

To access Adobe Target data as a PostgreSQL database, use the CData JDBC Driver for Adobe Target and a JDBC foreign data wrapper (FDW). In this article, we compile the FDW, install it, and query Adobe Target data from PostgreSQL Server.

Connect to Adobe Target Data as a JDBC Data Source

To connect to Adobe Target as a JDBC data source, you will need the following:

• Driver JAR path: The JAR is located in the lib subfolder of the installation directory.

• Driver class:

  cdata.jdbc.adobetarget.AdobeTargetDriver
  

• JDBC URL: The URL must start with "jdbc:adobetarget:" and can include any of the connection properties in name-value pairs separated with semicolons.

  To connect to Adobe Target, you must provide the Tenant property along with OAuth connection properties mentioned below. Note that while other connection properties can influence processing behavior, they do not affect the ability to connect.

  To determine your Tenant name:

  1. Log in to Adobe Experience. The URL will look similar to: "https://experience.adobe.com/#/@mycompanyname/preferences/general-section".
  2. Extract the value after the "/#/@". In this example, it is "mycompanyname".
  3. Set the Tenant connection property to that value.

  User Accounts (OAuth)

  You must set AuthScheme to OAuthClient for all user account flows.

  Note: Adobe authentication via OAuth requires updating your token every two weeks.

  All Applications

  CData provides an embedded OAuth application that simplifies OAuth authentication. Alternatively, you can create a custom OAuth application. Review Creating a Custom OAuth App in the Help documentation for more information.

  Obtaining the OAuth Access Token

  Set the following properties to connect:

  • InitiateOAuth: Set to GETANDREFRESH to automatically perform the OAuth exchange and refresh the OAuthAccessToken as needed.
  • OAuthClientId : Set to the client Id assigned when you registered your app.
  • OAuthClientSecret : Set to the client secret assigned when you registered your app.
  • CallbackURL : Set to the redirect URI defined when you registered your app. For example: https://localhost:3333

  With these settings, the provider obtains an access token from Adobe Target, which it uses to request data. The OAuth values are stored in the location specified by OAuthSettingsLocation, ensuring they persist across connections.

  Built-in Connection String Designer

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

  java -jar cdata.jdbc.adobetarget.jar
  

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

  

  A typical JDBC URL is below:

  jdbc:adobetarget:Tenant=mycompanyname;InitiateOAuth=GETANDREFRESH
  

Build the JDBC Foreign Data Wrapper

The Foreign Data Wrapper can be installed as an extension to PostgreSQL, without recompiling PostgreSQL. The jdbc2_fdw extension is used as an example (downloadable here).

1. Add a symlink from the shared object for your version of the JRE to /usr/lib/libjvm.so. For example:

   ln -s /usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server/libjvm.so /usr/lib/libjvm.so
   

2. Start the build:

   make install USE_PGXS=1
   

Query Adobe Target Data as a PostgreSQL Database

After you have installed the extension, follow the steps below to start executing queries to Adobe Target data:

1. Log into your database.
2. Load the extension for the database:

   CREATE EXTENSION jdbc2_fdw;
   

3. Create a server object for Adobe Target:

   CREATE SERVER AdobeTarget 
   FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS (
   drivername 'cdata.jdbc.adobetarget.AdobeTargetDriver',
   url 'jdbc:adobetarget:Tenant=mycompanyname;InitiateOAuth=GETANDREFRESH',
   querytimeout '15',
   jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.adobetarget.jar'); 
   

4. Create a user mapping for the username and password of a user known to the MySQL daemon.

   CREATE USER MAPPING for postgres SERVER AdobeTarget OPTIONS (
   username 'admin', 
   password 'test');
   

5. Create a foreign table in your local database:

   postgres=# CREATE FOREIGN TABLE activities (
   activities_id text,
   activities_Id text,
   activities_Name numeric) 
   SERVER AdobeTarget OPTIONS (
   table_name 'activities');
   

postgres=# SELECT * FROM activities;
