The RTSORAC Real-Time Object-Oriented Database Model and Prototype
نویسندگان
چکیده
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 imprecision elds; constraints on each of those elds; and semantically de ned compatibility of object methods. It also speci es rst-class relationships that can express inter-object constraints, and speci es time-constrained transactions with varying tolerances for data consistency. The implementation of the RTSORAC model in the Open Object-Oriented Database System is described.

RTSORAC: 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 کاملساختار دهی آنی داده‌‌های مکانی ورودی GIS با تأکید بر عارضه راه
An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...
