Real-Time Transaction Scheduling in Database Systems
A database system supporting a real-time application, which can be calledà real-time database system (RTDBS)', has to provide real-time information to the executing transactions. Each RTDB transaction is associated with a timing constraint, usually in the form of a deadline. EEcient resource scheduling algorithms and concurrency control protocols are required to schedule the transactions so as ...
متن کاملMulticlass Transaction Scheduling and Overload Management in Firm Real-Time Database Systems
Real-Time Database Systems (RTDBSs), have attracted considerable amount of research attention in the recent past and a number of important applications have been identi ed for such systems, such as telecommunications network management, automated air tra c control, automated nancial trading, process control and military command and control systems. Due to the rapidity of change of the system st...

متن کاملIntegrating Standard Transactions in Firm Real-Time Database Systems
Real-time database systems are designed to handle workloads where transactions have completion deadlines and the goal is to meet these deadlines. However, many real-time database environments are characterized by workloads that are a & of real-time and standard (non-real-time) transactions. Unfortunately, the system policies used to meet the performance goals of real-time transactions often wor...
متن کاملMaintaining Security in Firm Real-Time Database Systems
Many real-time database systems, such as military institutions and government agencies, are contained in environments that exhibit restricted access of information, where mandatory access control for security is required. Hence, in addition to timing constraints, real-time database systems have security constraints. Conventional multi-level secure database models are inadequate for time-critica...
