With a total of 7 patents to his name, Antoshenkov's work has had a lasting impact on how databases process and retrieve information.
Latest Patents
One of his latest patents is the Range-based Query Optimizer. This invention is a computerized query optimizer designed for use with a database system that contains an ordered set of records. The optimizer utilizes a scanner and an evaluator to enhance the efficiency of query processing. A query is structured as ranges of record values that are interconnected by logical operators. The system converts the query into a Boolean tree in canonical form, optimizing it to represent the ranges as a set of disjoint semi-open ranges. The scanner reads the next record from the database, while the evaluator determines a logical true or false condition for the record. Additionally, the evaluator provides an interval of values that share the same logical condition as the record. If the logical condition is false, the scanner bypasses records within that interval. Conversely, if the condition is true, the records within the interval are selected for processing.
