Latest Patents

One of his latest patents is titled "System for optimally processing a transaction and a query to the same." This invention focuses on concurrent processing of queries and transactions against a shared database. The system utilizes multiple processors, with one dedicated to processing queries and another for transactions. A query buffer is established to perform the query search while the data accessed by transactions is available in a database cache. Control logic within the database management system distinguishes between transactions and queries, initiating file-read control for reading the database file. This control structure ensures that the load from queries is managed effectively.

Another significant patent is the "System for parallel reading and processing of a file." This system incorporates multiple disks for file storage, connected to a data processing system via multiple input-output channels. A file buffer is created in the memory of the data processing system, shared by an instruction processor that initiates parallel read requests and manipulates the file data. Multiple input requests are processed in parallel, allowing for efficient data handling. Control structures are also implemented to manage the input processing demands placed on the system.
