Title: Chuck Freiwald: Innovator in Database Technology
Introduction
Chuck Freiwald is a notable inventor based in Milford, NH (US). He has made significant contributions to the field of database technology, holding a total of 2 patents. His work focuses on methods and apparatuses that enhance data storage and retrieval efficiency.
Latest Patents
Freiwald's latest patents include innovative solutions for database management. One of his patents describes a method and apparatus for efficiently storing and retrieving data in a database using index-only tables. This method involves storing an index entry in a leaf node that includes a key value along with all other values in the row of data. If the row exceeds a predetermined size, a portion of the data is stored in a user-specified overflow area. The retrieval process identifies a leaf node for the key and reads the data from the index entry and any remaining portion from the overflow area.
Another patent focuses on index-only tables with nested group keys. This invention provides a method for building, maintaining, and using a multi-level index accessed via a key divided into multiple portions known as sub-keys. The first level of the index is built on a first-level sub-key, with each entry either including sub-entries for second-level sub-keys or a reference to a second-level data retrieval structure. This structure reduces maintenance operations and increases concurrency in database systems, making it especially suited for queries that retrieve all values for a given first-level sub-key.
