Basic example on how to create batch operations using the hosted model. In this demo we have 4 employees and some daily sales informations for them in a database. Using that information, in a batch process, we generate for each employee a chart with its own month statistics.
Our first call is a PUT method, with some empty data ({}). Then, once we get the ZingId and LockCode at every step we fetch the information for that employee from database, do a PUT method (that updates the data) and then use the RENDER call to generate the image.
