Abstract
Many real-time systems are now being used in safety-critical
applications, in which human lives or expensive machinery may be at
stake. Examples include aerospace and defense systems, industrial
automation, traffic control, web-based information services, etc.
The unpredictable demands from the operating environments
of such systems often pose rigid requirements on
their timely performance. These requirements are defined as
real-time constraints on their temporal behavior.
As real-time systems continue to evolve, their applications become
more complex, and often require timely access to temporal data,
possibly from sensor devices. This need for advanced data services
in real-time applications poses intellectual and engineering
challenges to researchers and practitioners.
The trade-offs faced by the designers of real-time data services
are different from those faced by the designers of general-purpose
database systems.
In this talk, we first discuss characteristics of real-time systems
and some of the research issues of real-time data services.
We then present research work being performed at the University of
Virginia, especially on supporting QoS in real-time data services.
