Abstract: A database system is disclosed. The database system includes a common data repository, a document indexing database and a query engine. The common data repository is configured to store data in a common data table and is associated with a data object. The document indexing database is configured to store a data structure model that is associated with a unique document type. The data structure model is configured to facilitate retrieval of data stored in the common data table. The query engine is communicatively linked to the document indexing database and the common data repository. The query engine is configured to use the data structure model to retrieve data from the common data table.

Abstract: A computing system for performing digital sequential coordinate transformations on n dimensional vector input data referenced to a sensor system and ultimate outputting of the n dimensional vector data having basis in an alternate reference system in a form compatible with utilization equipment. The system adopts the basic "Cordic Algorithm" but eliminates the need for interim storage elements by the provision in a digital computing resolver of n registers, one for each of the n orthogonal axes plus a register for the rotation angle wherein the orthogonal registers are selected sequentially by the program in pairs to develop the terminal vector solutions. Additionally, the system provides a means of cross-addition between registers which reduces register capacity and eliminates the need for circuitry to perform trigonometric subroutines.
