Metode i postupci ubrzavanja operacija i upita u velikim sistemima baza i skladišta podataka (Big Data sistemi)

Abstract

Predmet istraživanja ove doktorske disertacije je mogućnost uspostavljanja modela Big Data sistema sa pripadajućom softversko – hardverskom arhitekturom za podršku senzorskim mrežama i IoT uređajima. Razvijeni model počiva na energetsko efikasnim, heterogenim, masovno paralelizovaim SoC hardverskim platformama, uz podršku softverske aplikativne arhitekture (poput OpenCL) za unifikovan rad. Pored aktuelnih hardverskih, softverskih i mrežnih računarskih tehnologija i arhitektura namenjenih za rad podkomponenata modelovanog sistema u radu je predstavljen istorijski osvrt na njihov razvoj. Time je naglašena tendencija cikličnog kretanja koncepcijskih paradigmi računarstva, kroz svojevrstne ere centralizacije – decentralizacije computinga. U radu su predstavljene tehnologije i metode za ubrzavanje operacija u bazama i skladištima podataka. Istražene su mogućnosti za bolju pripremu Big Data informacionih sistema koji treba da zadovolje potrebe novo najavljene informatičke revolucije opšte primene računarstva tzv. Ubiquitous computing-a i Interneta stvari (IoT).

The research topic of this doctoral thesis is the possibility of establishing a model for Big Data System with corresponding software-hardware architecture to support sensor networks and IoT devices. The developed model is based on energy efficient, heterogeneous, massively parallelized SoC hardware platforms, with the support of software application architecture. (Such as an open CL) for unified operation. In addition to current hardware, software and network computing technologies, and architecture intended to operate subcomponents of the system modeled in this paper is presented as an historical overview of their development. Which emphasizes the tendency of the cyclic movement of the conceptual paradigm of computing, through the unique era of centralization/decentralization of computing. The thesis presents the technology and methods to accelerate operations in databases and data warehouses. We also investigate the possibilities for a better preparation of Big Data information systems to meet the needs of the newly announced IT revolution in the announced general application of computing called Ubiquitous computing and the Internet of Things (IoT).
