A task-based query execution model with priority-based scheduling allows for an effective prioritization of query classes. This paper discusses the impact of task granularity on responsiveness and throughput of an in-memory DBMS . We show that a larger task size for long running operators ...

This process leads to increased testing costs in the execution phase and often weaker fault coverage. Most of the techniques in testing concurrent processes use the composition of control graphs known as the Communication Finite State Machine (CFSM) or the Communicating Extended Finite State Machine ...
Using Concurrent Statistics Gathering with Parallel Execution When using concurrent statistics gathering it is still possible to have each individual statistics gather job execute in parallel. This combination is normally used when the objects (tables or (sub)partitions) being analyzed are large. If you...
In this work we present an approach that predicts errors from a single trace of a parallel program. We compute alternative interleavings off-line to reduce the timing effects of the observed execution. Using a process algebra, we build a model that generalizes the ordering of the trace, ...

Currently there are some popular solutions preventing incorrect execution of concurrent business processes by using built-in transaction mechanisms and/or resource reservations in database management systems (DBMS). The proposed solution is an alternative, which can be used when resource locking or DBMS...
A distributed database system allows concurrent execution of transactions from multiple users at multiple locations. This paper presents a general scheme of including the effect of interaction between such transactions in the design process of distributed databases. This scheme allows the decision maker ...
