The δ Big Data Architecture for Mobility Analytics.

Motivated by needs in mobility analytics that require joint exploitation of streamed and voluminous archival data from diverse and heterogeneous data sources, this chapter presents the δ architecture: Denoting “difference,” δ emphasizes on the different processing requirements from loosely coupled components, which serve intertwined processing purposes, forming processing pipelines. The δ architecture, being a generic architectural paradigm for realizing big data analytics systems, contributes principles for realizing such systems, focusing on the requirements from the system as whole, as well as from individual components and pipelines. The chapter presents the datAcron integrated system as a specific instantiation of the δ architecture, aiming to satisfy requirements for big data mobility analytics, exploiting real-world mobility data for performing real-time and batch analysis tasks.
