Abstract:
1. A system for generating user defined timeshared derivative catalogs from a master catalog, comprising: A) a dynamic partitioning module configured to obtain user profile information and retrieve a user defined first view via a masking module; B) said masking module configured to provide said user defined first view to a first user by performing a bitwise AND operation between a first bit vector index and a second bit vector index to select a first view data record set from a plurality of data records in a master data set and by performing a bitwise AND operation between a third bit vector index and a fourth bit vector index to yield a first view data element set comprising a first view data record set having said first view data element set; said first bit vector index defining a first set of available data records in said master data set comprising a first single bit corresponding to a first available data record in said plurality of data records in said master data set; said second bit vector index defining a second set of available data records in said master data set comprising a second single bit corresponding to a second available data record in said plurality of data records in said master data set; said third bit vector index defining a first set of available data elements in said master data set comprising a third single bit corresponding to a first available data element in said plurality of data records in said master data set; and said fourth bit vector index defining a second set of available data elements in said master data set comprising a fourth single bit corresponding to a second available data element in said plurality of data records in said master data set; and C) a computer for executing the modules.
