EnterpriseDB JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with EnterpriseDB.



Use the CData JDBC Driver for EnterpriseDB to create a virtual data source for EnterpriseDB data in the Denodo Virtual DataPort Administrator.

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 EnterpriseDB, Denodo users can work with live EnterpriseDB data alongside other enterprise data sources. This article walks through creating a virtual data source for EnterpriseDB in the Denodo Virtual DataPort Administrator.

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

Create an EnterpriseDB Virtual Port

To connect to live EnterpriseDB 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 EnterpriseDB 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 EnterpriseDB\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-enterprisedb-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.: enterprisedb
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-enterprisedb-19
    • Driver class: cdata.jdbc.enterprisedb.EnterpriseDBDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

      jdbc:enterprisedb:User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444

      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 EnterpriseDB JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.enterprisedb.jar

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

      The following connection properties are required in order to connect to data.

      • Server: The host name or IP of the server hosting the EnterpriseDB database.
      • Port: The port of the server hosting the EnterpriseDB database.

      You can also optionally set the following:

      • Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

      Connect Using Standard Authentication

      To authenticate using standard authentication, set the following:

      • User: The user which will be used to authenticate with the EnterpriseDB server.
      • Password: The password which will be used to authenticate with the EnterpriseDB server.

      Connect Using SSL Authentication

      You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

      • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
      • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
      • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
      • SSLClientCertType: The certificate type of the client store.
      • SSLServerCert: The certificate to be accepted from the server.
  6. Click the "Test connection" button to confirm the configuration and click Save.

View EnterpriseDB Data in the VirtualPort Administrator Tool

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

  1. Click the "Create base view" button in the newly created VirtualPort (admin.EnterpriseDB).
  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 EnterpriseDB 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_enterprisedb_orders) 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_enterprisedb_orders 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 EnterpriseDB data like you would any other data source in Denodo Platform, for example, querying EnterpriseDB in the Denodo Data Catalog.
