jSchema

jSchema is going to create an object called jSchema. This object is a metadata representation of all your datasets containing the table names, column names, and keys that define sets. The data itself is stored within a closure within the object and is retrieved via a getter function. Joining data, aggregating data, and filtering data will create a new dataset in your WORK namespace that will persist on the page until either you delete the table or you run a cleanUp method.
