Chapter 7 . 30 A Formal Verification and Validation Approach for Real-Time Databases

Real-time database-management systems provide efficient support for applications with data and transactions that have temporal constraints, such as industrial automation, aviation, and sensor networks, among others. Many issues in real-time databases have brought interest to research in this area, such as: concurrence control mechanisms, scheduling policy, and quality of services management. However, considering the complexity of these applications, it is of fundamental importance to conceive formal verification and validation techniques for real-time database systems. This chapter presents a formal verification and validation method for real-time databases. Such a method can be applied to database systems developed for computer integrated manufacturing, stock exchange, network-management, and command-and-control applications and multimedia systems. In this chapter, we describe a case study that considers sensor networks.
