Zusammenfassung:Systems and methods for obtaining access to database files m a computing system. A method may include receiving a first call from a database management system requesting access to a database file. The method may further include transmitting a second call to an operating system interface requesting that a memory-mapped data expanse file be created. The method may also include receiving a first address representing the database file in response to successful mapping of the database file to the memory-mapped data expanse file located at the operating system interface.
