Abstract. In concurrent database systems, correctness of update transactions refers to the equivalent effects of the execution schedule and some serial schedule over the same set o...
This paper proposes an extension of the multiversion two phase locking protocol, called EMVZPL, which enables update transactions to use versions while guaranteeing the serializab...
We describe an eficient server-based algorithm for garbage collecting object-oriented databases in a client/server environment. The algorithm is incremental and runs concurrently ...

Based on loosely coupled services in an XML engine, we describe how to realize fine-grained lock protocols, which can guarantee transaction isolation for applications using differ...
The need for incremental constraint maintenance within collections of semi-structured documents has been ever increasing in the last years due to the widespread diffusion of XML. T...
