Overview

Applicasa's LiQuery class aims to ease and enhance the need to store necessary data in a remote datastore and subsequently query it from an application with minimal fuss. To that end, LiQuery provides the standard querying interface for all application data developers store in Applicasa, along with highly customizable filtering and paging operations.
