Replicated Data Management in Mobile Environments:
Anything New Under the Sun?
Database Group Faculty
The mobile wireless computing environment of the future will contain
large numbers of low powered palmtop machines. Replication will be
an essential technique in this environment, adding availability to
the system. In this talk I will discuss the existing techniques for replicated
management and discuss their applicability to mobile systems.
In particular, I will argue that not many changes are needed
to "traditional" algorithms to cope with mobility, in spite of
the many papers recently published on data management in
Hector Garcia-Molina is the Leonard Bosack and Sandra Lerner Professor
in the Departments of Computer Science and Electrical Engineering at
Stanford University, Stanford, California. From August 1994 to
December 1997 he was the Director of the Computer Systems Laboratory
at Stanford. From 1979 to 1991 he was on the faculty of the Computer
Science Department at Princeton University, Princeton, New Jersey.
His research interests include distributed computing systems and
database systems. He received a BS in electrical engineering from the
Instituto Tecnologico de Monterrey, Mexico, in 1974. From Stanford
University, Stanford, California, he received in 1975 a MS in
electrical engineering and a PhD in computer science in 1979.
Garcia-Molina is a Fellow of the ACM, received the 1999
ACM SIGMOD Innovations Award, and is a member of
the President's Information Technology Advisory Committee (PITAC).
