Systems and Methods for Asynchronous Searching and Filtering of Data

Abstract

An automation control and monitoring system includes a server configured to receive a subscription request from a client component. The subscription request provides one or more criteria to the server. The server is configured to provide a set of data, via a first notification, to the client component based upon the one or more criteria in the subscription request. The server is configured to provide, via additional notifications based on the subscription request, additional sets of data, modifications to the set of data, or both, when additional data or modifications corresponding to the one or more criteria are available.
