Research Description
Current developments in the area of database management (DBMS)
and information systems design aim to capture a wide
variety of applications into the fold of DBMS technology.
With these developments Database Systems are to be in use
within a diverse range of applications ranging from banking
and insurance companies to spacecraft monitoring applications.
Most of the recent advances add many types of transactions
and many types of processing constraints. This situation has led to
concentrated efforts by many researchers to find out
suitable transaction management strategies and alternatives.
One of the new areas of interest in transaction management is
that of systems in which transactions have time constraints.
Within the new
environment, the database management system must support a mix
of ordinary as well as time-critical (real-time) transactions.
The transaction support must also be highly reliable.
Traditional approaches to transaction management
introduce elements of unpredictable delays
during transaction processing, thus making these not
suitable for adoption in new application environments. Also,
in the past, studies have concentrated on separate investigations
of multiple problems, such as, scheduling, concurrency control,
and recovery.
Many new approaches that are more appropriate for the new environment
are being studied.
