Research/Educational Interests

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.
