Semantic Multi-granular Lock Model for Object Oriented Distributed Systems
In object oriented distributed systems (OODS), the objects are viewed as resources. Concurrency control techniques are usually applied on the database tier. This has the limitations of lack of support of legacy files and requirement of separate concurrency control mechanisms for each database model. Hence concurrency control on the objects at server tier is explored. To implement concurrency co...
متن کاملSemantic Multi-granular Lock Model in Object Oriented Database Systems
In this paper, a semantic based multi-granular lock model for object-oriented database systems is proposed. It addresses the concurrency control issues related to all types of transactions to an object: run time transactions and design time transactions. In the case of run time transactions, it ensures consistency while providing fine granularity. In the case of design time transactions, the pr...
متن کاملA Multi-Granular Lock Model for Distributed Object Oriented Databases Using Semantics
In object oriented databases, transactions may make simultaneous requests to do design time access and runtime access of resources. Concurrency control on the transactions can be implemented by using Multi granular lock models. Though several semantics based multi granular lock models have been proposed in the literature for object-oriented databases, they provide fine granularity of resources ...
متن کاملA Formal Model of Concurrency for Distributed Object-Oriented Systems
It is widely accepted that object-oriented constructions can be used as a pertinent basis for the support of distributed systems consisting of concurrently executing objects that communicate and interoperate among them. In this context, distributed object systems are representedfrom a process-oriented perspective which uses the process as the basic modelling structure. This point of view allows...
متن کاملAn Object-Oriented Semantic Model for .NET
Software engineering is a complex activity requiring software engineers to understand an intricate structure of components, with many different inter-relationships. In object-oriented software, these components include classes, interfaces, fields, methods and other entities. Relationships include inheritance, implementation, containment, invocation and many more. Static analysis of source code ...
