Introduction
Sebastian Hofstetter is an innovative inventor based in Munich, Germany. With a total of two granted patents, he has made significant contributions to the field of database technology, specifically in optimizing query execution.
Latest Patents
Hofstetter's latest patent focuses on "Computing domain cardinality estimates for optimizing database query execution." This method enhances the optimization process by computing estimates of distinct data values for database queries. When a client sends a query to the server, the method parses it to identify relevant data columns. For each column, it computes both a lower bound and an upper bound of distinct data values using a pre-computed table size. It also calculates a patch factor through a ratio derived from the distinct values that appear only once in a sample. Utilizing these calculations, the method constructs an execution plan tailored to the computed estimates, which executes the query and returns the result set to the client. This inventive approach significantly improves the efficiency of database query execution.
