A PostgreSQL Interface for Basecamp Data

Use the Remoting features of the Basecamp JDBC Driver to create a PostgreSQL entry-point for data access.

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

Connect to Basecamp Data as a JDBC Data Source

To connect to Basecamp 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.basecamp.BasecampDriver

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

    Basecamp uses basic or OAuth 2.0 authentication. To use basic authentication you will need the user and password that you use for logging in to Basecamp. To authenticate to Basecamp via OAuth 2.0, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties by registering an app with Basecamp.

    See the Getting Started section in the help documentation for a connection guide.

    Additionally, you will need to specify the AccountId connection property. This can be copied from the URL after you log in.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.basecamp.jar

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

    A typical JDBC URL is below:

    jdbc:basecamp:User=test@northwind.db;Password=test123;

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.

  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 Basecamp Data as a PostgreSQL Database

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

  1. Log into your database.
  2. Load the extension for the database: CREATE EXTENSION jdbc2_fdw;
  3. Create a server object for Basecamp: CREATE SERVER Basecamp FOREIGN DATA WRAPPER jdbc2_fdw OPTIONS ( drivername 'cdata.jdbc.basecamp.BasecampDriver', url 'jdbc:basecamp:User=test@northwind.db;Password=test123;', querytimeout '15', jarfile '/home/MyUser/CData/CData\ JDBC\ Driver\ for\ Salesforce MyDriverEdition/lib/cdata.jdbc.basecamp.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 Basecamp OPTIONS ( username 'admin', password 'test');
  5. Create a foreign table in your local database: postgres=# CREATE FOREIGN TABLE projects ( projects_id text, projects_Name text, projects_DocumentsCount numeric) SERVER Basecamp OPTIONS ( table_name 'projects');
You can now execute read/write commands to Basecamp: postgres=# SELECT * FROM projects;
