In the field of computer science, data is considered as the main raw material which is produced by abstracting the world into categories, measures, and other representational forms (e.g., characters, numbers, relations, sounds, images, electronic waves) that constitute the building blocks from which information and knowledge are created. In practice, data generation and consumption has become a part of people’s daily life especially with the pervasive availability of Internet technology. We are progressively moving toward being a data-driven society where data has become one of the most valuable assets. Big data has commonly been characterized by the defining 3V’s properties which refer to huge Volume, consisting of terabytes or petabytes of data; high in Velocity, being created in or near real time; and diversity in Variety of form, being structured and unstructured in nature. Recently, research communities, enterprises, and government sectors have all realized the enormous potential of big data analytics, and continuous ad- vancements have been emerging in this domain. This Encyclopedia answers the need for solid and comprehensive research source in the domain of Big Data Technologies. The aim of this Encyclopedia is to provide a full picture of various related aspects, topics, and technologies of big data including big data enabling technologies, big data integration, big data storage and indexing, data compression, big data programming models, big SQL systems, big streaming systems, big semantic data processing, graph analytics, big spatial data management, big data analysis, business process analytics, big data processing on modern hardware systems, big data applications, big data security and privacy, and benchmarking of big data systems. With contributions of many leaders in the field, this Encyclopedia provides the reader with comprehensive reading materials for a large range of audi- ences. It is a main aim of the Encyclopedia to influence the readers to think further and investigate the areas that are novel to them. The Encyclopedia has been designed to serve as a solid and comprehensive reference not only to expert researchers and software engineers in the field but equally to students and junior researchers as well. The first edition of the Encyclopedia contains more than 250 entries covering a wide range of topics. The Encyclopedia’s entries will be updated regularly to follow the continuous advancement in the domain and have up-to-date coverage available for our readers. It will be available both in print and online versions. We hope that our readers will find this Encyclopedia as a rich and valuable resource and a highly informative reference for Big Data Technologies.
