Presents the architecture of /spl Bscr/eSS (Bell Laboratories Storage System)-a high-performance configurable database storage manager providing key facilities for the fast development of object-oriented, relational or home-grown database management systems. /spl Bscr/eSS is based on a multi-client multi-server architecture offering distributed transaction management facilities and extensible support for persistence. We present some novel aspects of the /spl Bscr/eSS architecture, including a fast object reference technique that allows re-organization of databases without affecting existing references, and two operation modes that an application running on a client or server machine can use to interact with the storage system-(i) copy on access and (ii) shared memory.
