Abstract Large data is the source of interest of analytics which are made their decisions rely upon historical data, for them big data is used to build the necessary reports on them to be able to get the required information, analyze it and use it for decision making. This article examines the latest developments in data analysis, as well as the benefits of analyzing large volumes of data for businesses. The article also describes proposals for the optimization of data processing systems, integrating them into a single infrastructure for a more rapid and "smart" business decision making. Keywords: Big data, decision making, data mining; * ADDRESS FOR CORRESPONDENCE: Kalamkas Nurlybayeva, al-Farabi Kazakh National University, PhD student, Kabanbay batyr st. 135, flat 1, Almaty, 010012, Kazakhstan, E-mail address: kalamkas.nurlybayeva@gmail.com / Tel.: +7-777-837-6777
