Abstract: 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.

Abstract: A method for processing digital images includes receiving from one of a plurality of sensors a first image in a first format. A first set of metadata is associated with the first image. The method also includes generating a second set of metadata based on at least the first set of metadata and a configuration file. The configuration file identifies metadata to be included in the second set of metadata. Additionally, the method includes converting the first image in a first format into a second image in a second format and storing the second set of metadata in a metadata database. The method further includes receiving search parameters from clients, identifying one or more sets of metadata corresponding to the search parameters, and transmitting to a client one or more images associated with the identified sets of metadata.
