Abstract: A mechanism is provided for storing data files in a file system. The file system provides a plurality of reference data files, where each reference data file in the plurality of data files represents a group of similar data files. The mechanism creates a new data file and associated the new data file with one reference data file in the plurality of data files thus defining an associated reference data file of the plurality of reference data files. The mechanism informs the file system about the association of the new data file with the associated reference data file. The mechanism compresses the new data file using the associated reference data file thereby forming a compressed data file. The mechanism stores the compressed data file together with information about the association of the new data file with the associated reference data file.

Abstract: A query builder provided according to an aspect of the present invention facilitates users to conveniently generate database queries directed to database servers storing data elements organized according to attributes. In an embodiment, configuration data indicating a comparison predicate to be used for each combination of an attribute and a conditional operation is maintained. A user may then provide as inputs a first attribute, a first conditional operation and a first value. In response, the query builder examines the configuration data to determine a first comparison predicate specified for the combination of the first attribute and the first conditional operation. The query builder incorporates the first value in the first comparison predicate to construct a second comparison predicate and then forms a first database query with the second comparison predicate.

Abstract: A synchronized incident response system is distributed across one or more user devices and a host server. Each device has a stored version of an incident response profile for a defined location, the profile having version numbers corresponding to a set of data values for one or more attributes specific to the defined area. Each device is linked to the server and can transmit data records with changes to profile attributes, wherein the server determines whether the user changes are valid updates with respect to what is already stored in server memory. If so, the server synchronizes the profile attributes to generate a current profile and generates incremented version numbers. Each device can provide an incident response request for the defined area to the server, wherein the server generates an incident response report populated with data corresponding to a latest version number for each of one or more predetermined attributes.
