Relational database systems are well-suited as a platform for data-centric XML processing. Data-centric applications process regularly structured XML documents using precise predicates. ...
Moreover, we show that document-centric XML processing is efficiently feasible using relational database systems for storage management and standard SQL. ...
To increase the flexibility of retrieval granularities for searching XML, Fuhr et al. group XML elements (at the instance level) to so-called indexing nodes [13] . ...
