Answering UCQs under updates and in the presence of integrity constraints
Christoph Berkholz, Jens Keppeler, Nicole Schweikardt
We investigate the query evaluation problem for fixed queries over fully dynamic databases where tuples can be inserted or deleted. The task is to design a dynamic data structure t…
Answering FO+MOD queries under updates on bounded degree databases
Christoph Berkholz, Jens Keppeler, Nicole Schweikardt
We investigate the query evaluation problem for fixed queries over fully dynamic databases, where tuples can be inserted or deleted. The task is to design a dynamic algorithm that…
Answering Conjunctive Queries under Updates
Christoph Berkholz, Jens Keppeler, Nicole Schweikardt
We consider the task of enumerating and counting answers to -ary conjunctive queries against relational databases that may be updated by inserting or deleting tuples. We exhibit…
