In one embodiment, a database access system includes a remote client application, a database having a plurality of data records, and a data event agent. The database has a plurality of data records and is coupled to the data event agent. The data event agent is remotely coupled to the remote client application through a firewall and operable to receive a query from the remote client application. In response to receipt of the query, the data event agent stores the query in memory in order to continually filter additions and modifications to data records against the one or more filter criteria included in the query. In the event that a data record matches the query, the data event agent transmits the data record to the remote client application.
