The traditional wisdom for building disk-based relational DataBase Management Systems (DBMS) is to organize data in heavily-encoded blocks stored on disk, with a main memory block cache. In order to improve performance given high disk latency, these systems use a multi-threaded architecture with dynamic record-level locking that allows multiple transactions to access the database at the same time. Previous paper has shown that this results in substantial overhead for On-Line Transaction Processing (OLTP) applications. The next generation DBMSs seek to overcome these limitations with architecture based on main memory resident data.
