A High Level Query Language for Big Data Analytics

We present a high level query language for expressing analysis tasks as queries over big data sets, independently of how the analysis task is to be carried out or what are the computing resources used by the system and what is the structure and physical layout of data: a query in our language is defined at the conceptual level and then mapped to lower level evaluation mechanisms for computing the answer. Our overall objective is to have query formulation done on an abstract level, while actual query evaluation can adapt to the evaluation mechanisms offered in each case.
