Now that you have a table with data in it, you need to be able to access the data and for that you will need to create and .xsodata file which defines an OData service. To start create a new sub package for your services.

Next create a new file library.xsodata and add the following code to it, the file name itself is only important in the sense that it is part of the URL when it is called most important though is that the ending of the file is .xsodata

service namespace "codejam.services" {
	"codejam.data::mydata.Book" as "library";
}

At this point you should be able to launch your XSODATA file in your browser or right click and choose the OData Explorer to view and see the data from your table.

Congratulations: You have just enabled a simple REST interface for your application.
