Integrate NASA data with visual data analysis tools and data connection wizards in DBVisualizer

The CData API Driver for JDBC implements JDBC standards to provide connectivity to NASA data in applications ranging from business intelligence tools to IDEs. This article shows how to establish a connection to NASA data in DBVisualizer and use the table editor to load NASA data.

Create a New Driver Definition for NASA Data

Follow the steps below to use the Driver Manager to provide connectivity to NASA data from DBVisualizer tools.

  1. In DBVisualizer, click Tools -> Driver Manager.
  2. Click the plus sign "" to create a new driver.
  3. Select "Custom" as the template.
  4. On the Driver Settings tab:
  5. The Driver Class should populate automatically. If not, select class (cdata.jdbc.api.APIDriver).
๐Ÿ‘ The configured JDBC driver. (Salesforce is shown.)

Define the Connection to the JDBC Data Source

Close the "Driver Manager" and follow the steps below to save connection properties in the JDBC URL.

  1. In the "Databases" tab, click the plus sign "" and select the driver you just created.
  2. In the "Connection" section, set the following options:

    • Database Type: If you selected the wizard option, the database type is automatically detected. If you selected the "No Wizard" option, select the Generic or Auto Detect option in the Database Type menu.
    • Driver Type: Select the driver you just created.
    • Database URL: Enter the full JDBC URL. The syntax of the JDBC URL is jdbc:api: followed by the connection properties in a semicolon-separated list of name-value pairs.

      Using API Key Authentication

      Most NASA API endpoints (APOD, NeoWS, DONKI, TechTransfer) require a NASA API key. Register for a free key at https://api.nasa.gov. The default DEMO_KEY provides limited access (30 requests/hour, 50 requests/day); a registered key allows 1,000 requests/hour.

      The following endpoints do not require an API key and work without authentication: EONET (Earth Observatory Natural Event Tracker), EPIC (Earth Polychromatic Imaging Camera), NASA Image and Video Library, and TechPort.

      After obtaining your API key, set the following connection properties:

      • AuthScheme: Set this to APIKey.
      • APIKey: Set this to your NASA API key. Use DEMO_KEY for limited testing.

      Example Connection String

      Profile=C:\profiles\NASA.apip;AuthScheme=APIKey;APIKey=YOUR_NASA_API_KEY
      

      Connecting to NASA

      Once the authentication is configured, you can connect to NASA and query data from any of the available tables such as AstronomyPictureOfDay, NearEarthObjectFeed, EonetEvents, and NasaImageLibrary.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.api.jar
      

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

      ๐Ÿ‘ Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)

      When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

      A typical connection string is below:

      jdbc:api:Profile=C:\profiles\NASA.apip;AuthScheme=APIKey;APIKey=YOUR_NASA_API_KEY
      
    • NOTE: Since NASA does not require a User or Password to authenticate, you may use whatever values you wish for Database Userid and Database Password.
  3. On the Connection tab, click Connect. ๐Ÿ‘ A newly configured Database Connection. (Salesforce is shown.)

To browse through tables exposed by the NASA JDBC Driver, right-click a table and click "Open in New Tab."

To execute SQL queries, use the SQL Commander tool: Click SQL Commander -> New SQL Commander. Select the Database Connection, Database, and Schema from the available menus.

See the "Supported SQL" chapter in the help documentation for more information on the supported SQL. See the "Data Model" chapter for table-specific information.
