Real-time database systems must maintain both logical and temporal data integrity so that transactions can respond to real-world events timely and predictably. For real-time applications, such as avionics and process control, that are connected to sensor devices, the consistency between the device readings and the current values used by transactions could be more important than the serializability of transactions. In this paper, we propose a semantic-based concurrency control protocol that increases the responsiveness of transactions. A method compatibility matrix is created for each object in the database. Transactions request different types of methods according to their consistency requirements. We show the performance of the semantic-based concurrency control protocol by simulation.
