Latest Patents

Greg's latest patents focus on multi-query optimization methods for database queries that include predicates. These queries are directed to at least one database table containing data organized in rows and columns. The optimization method involves associating a lineage bit set with each row of the database table. This lineage bit set provides a binary predicate state indication of whether each predicate is met or not met by the data in the row. Additionally, a dependency bit set is established to indicate the predicates included in each query. The queries are applied against the database table through a logical operation between the lineage bit set and the dependency bit set. This innovative data structure significantly improves the efficiency of database query processing.
