This research is concerned with novel Web-related data management
scenarios. In particular, we consider database problems which arise from
social networks. In the talk, we will overview the main results of
In the first part, we introduce the Query Network model, a basic model for
social network automation using queries, with its evaluation algorithms and
related experiments. We also discuss extensions for the model, and present
a few theoretical results.
In the second part, we discuss social networks automation using Protocols
for Social Networks, which coordinate consistency-preserving decisions in
the network. Methods for the concurrent execution of multiple protocol
instances, which relax the traditional concurrency control isolation
requirement, are presented.
In the third part, we describe XPath^L language and system, which combines
XPath, an XML query language, and Datalog, by introducing an XPath
predicate to the Datalog logic-based formalism. We overview algorithms and
related theoretical results.
