Import Real-Time NASA Data via ODBC in ColdFusion to Build Applications

Use CData ODBC drivers to import and use NASA data in ColdFusion.

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST. When ColdFusion is paired with the CData API Driver for ODBC, you can link your ColdFusion web and mobile applications to operational NASA data. This allows for your applications to be more robust and complete. This article details how to use the ODBC driver to create a table populated with NASA data from within a ColdFusion markup file.

To follow along with this tutorial, you need to install the CData API Driver for ODBC and Adobe ColdFusion.

Configuring the Connection

If you have not already, first specify connection properties in an ODBC DSN (Data Source Name). This is the last step of the driver installation process. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Adding a Data Source and Creating a Table

After creating a DSN, follow the steps below to add a new data source, test our connection to it, create a ColdFusion markup file, and, finally, import NASA Data and display it in a table in ColdFusion:

  1. From the ColdFusion administrator interface, choose Data & Services. 👁 Selecting Data & Services
  2. Here, click "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our ODBC driver, choose "ODBC Socket", then click the "Add" button. 👁 Adding Data Source Name
  3. From the ODBC DSN Dropdown menu select CData NASA Sys. Under the Advanced Settings section, leave the Connection String blank. Note that any properties specified in this input field will override the ones specified in the DSN Configuration. 👁 Populating driver properties
  4. Now, test the connection by pressing the check mark to the left of the CDataNASAODBC data source you just created. When the data source reports an "OK" status, it is ready for use. 👁 Testing the connection
  5. Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

    The following code queries the data source: 

     
 <cfquery name="NASAQuery" dataSource="CDataNASAODBC"> 
 SELECT * FROM AstronomyPictureOfDay 
 </cfquery>
    And a CFTable can be used to quickly output the table in HTML: 
     
 <cftable 
 query = "NASAQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 

 <cfcol header="<b></b>" align="Left" width=2 text=""/> 

 <cfcol header="<b></b>" align="Left" width=15 text=""/> 

 ...

 </cftable>
    Full code, including the HTML portion is available below: 
     
 <html> 
 <head><title>CData Software | NASA AstronomyPictureOfDay Table Demo </title></head> 
 <body> 
 <cfoutput>#ucase("NASA AstronomyPictureOfDay Table Demo")#</cfoutput> 
 <cfquery name="NASAQuery" dataSource="CDataNASAODBC"> 

 SELECT * FROM AstronomyPictureOfDay 

 </cfquery> 
 <cftable 
 query = "NASAQuery" 
 border = "1" 
 colHeaders 
 colSpacing = "2" 
 headerLines = "2" 
 HTMLTable 
 maxRows = "500" 
 startRow = "1"> 
 <cfcol header="<b></b>" align="Left" width=2 text=""/> 

 <cfcol header="<b></b>" align="Left" width=15 text=""/> 

 ...

 </cftable> 
 </body> 

 </html>
  6. Finally, run the code in a browser. It produces a table populated with NASA data! 👁 Running the code

As a note, the CData ODBC Drivers also support parameterized queries using the cfqueryparam element. For example: 

SELECT * FROM Account WHERE name =
