Presenting XML Schema Mapping with Conjunctive-Disjunctive Viewsmapping. A CDV is a pattern-based view which allows disjunctive as well as conjunctive composition of data elements. It can conveniently present complex mapping requests involving hierarchical, heterogeneous and even recursive data. We describe the design issues and the features of CDV, with certain typical examples of XML schema mappings.

A Framework for Analyzing Monetary Cost of Database Systems in the Cloudst model. As a case study of our proposed framework, we conduct an in-depth study on two popular open-source database systems with respect to two cloud providers. We find that evaluating a query spans a wide range of monetary costs (with a difference up to 91%), and the experimental results demonstrate the accuracy of our monetary cost estimation.
