Providing separate real-time and configuration segments in a database. The real-time segment provides real-time data values to a real-time application and the configuration segment provides configuration data values to the real-time application. Utilizing two or more configuration segments enables changes to configuration data values without impacting real-time applications.

Transactional integrity in a segmented database architecture

Providing double-buffered record locking in a database architecture. Double-buffered database records enable multiple parallel read locks substantially simultaneously with one write lock to eliminate lock collisions between the read locks and the write lock.

Double-buffered locking in a database architecture

First in, first out (FIFO) memory queue architecture enabling a plurality of writers and a single reader to use the queue without mutual exclusive locking. The FIFO queue is implemented using an array. A write counter value associated with the array provides a reservation value to each writer that is mutually exclusive of the value provided to every other writer. A read counter value associated with the array prevents writers from writing over data messages stored in the array that are yet to be read by the single reader.
