Creating a Data Service with Introduce

Data services may be created using the Introduce toolkit in conjunction with the data services extension.

Start Introduce from the top level of your caGrid installation:

ant introduce

When Introduce starts, click the "Create caBIG Service" button, and select the radio button to create a Data Service.

Creating a Data Service with Introduce

Click the OK button to proceed. Introduce will generate some of the basic code required for a caGrid service, and then it will invoke the data service extension. This extension provides a means for the service developer to choose what type of data source they wish to expose to the grid. The data service extension itself supports a pluggable architecture called "styles." These styles can be used to create highly custom data services in a repeatable, and user-friendly way. Out of the box, caGrid data services supply styles which support several versions of the caCORE SDK. Additionally, a service developer may choose a custom data source, in which case a custom CQL query processor must be implemented.

Creating a data service using one of the supplied styles supporting the caCORE SDK is covered in a separate document.
