Implementation of Generalized Relational Algebraic Operations with AsterixDB BDMS

Abstract

Every year data with a large volume and variety to be processed is growing. Such data handling requires special approaches, methodologies and tools. One of the most important parts of manipulating information is a high-level declarative query language that helps us not only to solve a lot of kinds of problems, but gives us great possibility for optimization. In this paper there will be considered a practical part of approach that introducing an extended relational algebra from [1]. This algebra can be used by query optimizer based on cost models. Implementation of generalized algebraic operations that uses big data management system AsterixDB [2], a cost model for estimation and optimization is the main aim of this work. © Springer International Publishing Switzerland 2015.
