Temporal order optimizations of incremental joins for composite event detection
Queries for composite events typically involve the four complementary dimensions of event data, event composition, relationships between events (esp. temporal and causal), and acc...

Isolating Order Semantics in Order-Sensitive XQuery-to-SQL Translation
Order is essential for XML query processing. Efficient XML processing with order consideration over relational storage is non-trivial, especially for complex nested XQuery expressi...

Semantic Query Optimization for XQuery over XML Streams
We study XML stream-specific schema-based optimization. We assume a widely-adopted automata-based execution model for XQuery evaluation. Criteria are established regarding what s...

Managing the operator ordering problem in parallel databases
This paper focuses on parallel query optimization. We consider the operator problem and introduce a new class of execution strategies called Linear-Oriented Bushy Trees (LBTs). Co...
