Abstract

Abstract: Data science requires the creation of complex data ecosystems to support data analysis, which we refer to as data-based information systems (DBIS). The diversity of techniques to manage and analyse data has contributed to a wide variety of DBIS. On the one hand, current data management solutions span classical relational databases, distributed (relational and non-relational) systems, document-oriented databases, column stores, in-memory databases, property and knowledge graph databases, stream processors, scientific databases, etc. On the other hand, data analytics techniques range from classical statistical-based data mining, to machine learning, process-oriented data analysis, stream and complex event processing, graph analytics, etc. On top of that, hardware-accelerated solutions, specially related to deep learning and CPU-intensive analytical solutions are complicating the big picture. Nowadays, a prominent research trend is to devise specific data management techniques to accelerate and improve the overall throughput and answer time of DBIS. DOLAP, the International Workshop On Design, Optimization, Languages and Analytical Processing of Big Data, has become a reference discussion forum where to witness the current advances in data management for modern data analytics needs. We summarize the advances presented in DOLAP 2020 and the best papers selected for the DOLAP 2020 Information Systems Special Issue.
