Integrate Twitter data into dashboards in TIBCO Spotfire.
OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData Connect Server provides Twitter data to OData consumers like TIBCO Spotfire. This article shows how to use the Connect Server and Spotfire's built-in support for OData to access Twitter data in real time.
Configuring Connect Server
To work with live Twitter data in TIBCO Spotfire, we need to connect to Twitter from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Twitter data.
Add a Connect Server User
Create a User to connect to Twitter from TIBCO Spotfire through Connect Server.
- Click Users -> Add
- Configure a User
- Click Save Changes and make note of the Authtoken for the new user
Connect to Twitter from Connect Server
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open Connect Server and click Connections
- Select "Twitter" from Available Data Sources
- Enter the necessary authentication properties to connect to Twitter.
All tables require authentication. You can connect using your User and Password or OAuth. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own.
If you intend to communicate with Twitter only as the currently authenticated user, then you can obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app.
See the Getting Started chapter in the help documentation for a guide to using OAuth.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).
Add Twitter OData Endpoints in Connect Server
After connecting to Twitter, create OData Endpoints for the desired table(s).
- Click OData -> Tables -> Add Tables
- Select the Twitter database
- Select the table(s) you wish to work with and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.
- Enable cross-origin resource sharing (CORS): ON
- Allow all domains without '*': ON
- Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
- Access-Control-Allow-Headers: Authorization
Save the changes to the settings.
Create Data Visualizations on External Twitter Data
- Open Spotfire and click Data -> Add data...
- Then, click "Connect to" -> OData -> New Connection. In the OData Connection dialog, enter the following information:
- Service URL: Enter the Connect Server's OData endpoint. For example:
http://localhost:8080/odata.rsc
- Authentication Method: Select Username and Password.
- Username: Enter the username of a Connect Server user. You can create API users on the Security tab of the administration console.
- Password: Enter the authtoken of a Connect Server user.
- Service URL: Enter the Connect Server's OData endpoint. For example:
- Select the tables and columns you want to add to the dashboard. This example uses Tweets.
-
If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.
If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.
- After you have selected a table, Spotfire uses the data to detect number, time, and other categories. You are now on your way to creating new visualizations for analytics, reporting, and more.
