Abstract

Active Transactions is a novel approach for Collaborative Virtual Environments (CVE). It is based on the transaction concept from database systems, however it was adapted to fit better the requirements of CVE.The transactions brings new benefits for CVE. They guarantee atomic execution of their updates. They provide advanced consistency guarantees that may result in simpler application design, and the speculative transaction execution enables to exploit prediction algorithms to provide an user with high responsiveness.The transaction concept is combined with active replication of the scene data. Active replication enables some performance optimizations of the transaction concept. Therefore, we call it active transaction approach.
