Transformation-Based Concurrency Control in Groupware Systems
This thesis explores the problem of maintaining a consistent shared state in replication-based groupware systems. Whereas more traditional systems might maintain consistency via locking mechanisms, we consider a transformation-based approach that creates the illusion of a common execution history across all sites in the system. In this thesis, we develop a formal treatment of the theory of oper...
متن کاملNotes on Concurrency Control in Groupware
These brief notes explore the requirements and design issues surrounding concurrency control in groupware – software with which several users, often geographically separated, collaborate on a shared task such as document writing. The next section gives an overview of groupware. We then give requirements and design issues, and go on to discuss how traditional concurrency control techniques such ...
متن کاملA Survey of Concurrency Control Algorithms in the Operating Systems
Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...

متن کاملA Novel Concurrency Control Algorithm in Distributed Groupware
We present a new approach for solving the concurrency control problem in completely distributed collaborative applications. The main advantages of our approach are the simplicity of use and good responsiveness as there are no lock mechanisms. The general structure of the algorithm is application independent, which it makes it suitable for general collaboration frameworks. The algorithm applies ...
