IMPORTANT!

Please use JaySvcUtil for node for JayData 1.5+ versions. This repository is left here to support JayData 1.3.6, but newer versions require the node-based tool. 

JaySvcUtil.exe is a command line tool that downloads an OData service definition ($metadata) and creates a full featured JayData / JavaScript client environment by generating the necessary boilerplate code for you. All you need to do is to include the generated context file and you can start using the OData service with the high level, JavaScript optimized JayData API that supports JavaScript Language Query (JSLQ) and crud operations.

If you are a data API developer you can distribute the generated context and let your users handle data with a manner.

As an example we will use the Northwind database made available online for testing purposes by Microsoft.
