The RTSORAC Real-Time Object-Oriented Database Model and Prototype
This paper presents a model and prototype implementation of a real-time objectoriented database system. In addition to traditional database system requirements, a real-time database must support data temporal consistency requirements and timeconstrained transactions. The RTSORAC database model supports these requirements by specifying objects that contain: attributes with value, time and imprec...
متن کاملRTSORAC: A Real-Time Object-Oriented Database Model
A real-time database is a database in which both the data and the operations upon the data may have timing constraints. We have integrated real-time, object-oriented, semantic and active database approaches to develop a formal model called RTSORAC for real-time databases. This paper describes the components of the RTSORACmodel including objects, relationships, constraints, updates, and transact...
متن کاملRTSORAC : Design of a Real - Time Object - Oriented Database
A real-time database is a database in which both the data and the operations upon the data may have timing constraints. To provide logical and temporal correctness, these constraints must be well integrated into the static and dynamic constructs of the model used to specify the database. The RTSORAC (Real-Time Semantic Objects Relationships And Constraints) group at the University of Rhode Isla...
متن کاملThe design of real-time extensions to the Open Object Oriented Database system
This paper describes real-time extensions to the Open Object-Oriented Database system using the RTSORAC data model. This model combines an objectoriented data model, real-time requirements, exible transactions, semantic relationships among objects, and active database features. Several extensions to the Open Object-Oriented Database system, including development of interfaces for real-time obje...
متن کاملAn Object - Oriented Real - Time Databasesystem for Multiprocessors
AN OBJECT-ORIENTED REAL-TIME DATABASE SYSTEM FOR MULTIPROCESSORS. by Victor Bradley Lortz Chair: Kang G. Shin Complex real-time systems need databases to support concurrent data access and provide well-de ned interfaces between software modules. However, conventional database systems and prior real-time database systems do not provide the performance or predictability needed by high-speed, hard...
