A Real-Time DataBase System (RTDBS) can be viewed as an
amalgamation of a conventional DataBase Management System (DBMS) and a
real-time system. Like a DBMS, it has to process transactions and
guarantee ACID database properties. Furthermore, it has to operate in
real-time, satisfying time constraints imposed on transaction
commitments. A RTDBS may exist as a stand-alone system or as an
embedded component in a larger multidatabase system. The publication
in 1988 of a special issue of ACM SIGMOD Record on Real-Time DataBases
signaled the birth of the RTDBS research area---an area that brings
together researchers from both the database and real-time systems
communities. Today, almost eight years later, I am pleased to present
in this special section of ACM SIGMOD Record a review of recent
advances in RTDBS research. There were 18 submissions to this special
section, of which eight papers were selected for inclusion to provide
the readers of ACM SIGMOD Record with an overview of current and
future research directions within the RTDBS community. In this paper, I summarize these
directions and provide the reader with pointers to other publications
for further information.
