This question examines the basic concepts of big data; Refer to the tutorial of system integration project management engineer (2nd edition) p145; ;

1. Big data is data with the characteristics of large volume, diverse structure and strong timeliness (D option), and new technologies such as new computing architecture and intelligent algorithms need to be adopted to deal with big data. Big data generally needs to go through five main links from data source analysis and mining to final value acquisition, including data preparation, data storage and management, calculation and processing, data analysis and knowledge presentation. Big data technology involves data model, processing model, computing theory, and related research and development achievements in distributed computing, distributed storage platform technology (C option), data cleaning and mining technology, stream computing, incremental processing technology, data quality control and so on. Big data technology products have also entered the commercial stage.

2. Like water, minerals and oil, big data is becoming a new natural resource. Whether the potential value of resources can be tapped has become an important condition for creating wealth in this era. (b option)
