Latest Patents
One of Schuetzner's latest patents is titled "Automatic maintenance of a set of indexes with different currency characteristics in a database management system." This invention involves methods and apparatus, including computer program products, for maintaining a set of indexes in a database management system (DBMS) that has at least one table. The patent defines a current, stale, or deferred status for a part of the indexes, resulting in a set of current, stale, or deferred indexes in the DBMS. Current indexes are maintained by refreshing them synchronously with table changes. Stale indexes are refreshed continuously and asynchronously based on log information, while deferred indexes are built in response to queries, ensuring they align with the current status of the table.
Another significant patent by Schuetzner is related to "Processing of restricted data." This invention addresses the operation of a data processing system by receiving requests for data storage that include restricted-access data. It involves encrypting this data with a cryptographic key and defining a masking rule for its storage. The process ensures that the restricted-access data can be reconstructed when retrieved from a shared database.
