An article on dry goods lets you understand big data collection techniques
Big data opens up an era of mass production, sharing and application of data that has brought about tremendous changes in technology and commerce. McKinsey research shows that in the medical, retail and manufacturing sectors, big data can increase labor productivity by 0.5 to 1 percentage point a year. The penetration of big data in the core areas is evident to all, but surveys show that up to 99.4% of unused information is in large part due to the inability to capture high-value information. Therefore, in the context of big data era, how to collect useful information from big data is one of the key factors in the development of big data. So what is big data collection technology? This issue introduces big data collection technology to let We easily understand the big data collection.
% What is data collection?
Data Acquisition (DAQ), also known as data acquisition, refers to the process of automatically acquiring information from analog and digital units under test, such as sensors and other equipment under test. Data classification In the new generation data system, the new data sources not considered in the traditional data system are summarized and classified into two categories: online behavior data and content data.
? Online behavior data: page data, interactive data, form data, session data.
Content data: application logs, electronic documents, machine data, voice data, social media data, etc.
Major sources of big data: 1) Business data 2) Internet data 3) Sensor data
%? Data collection and big data collection difference
%? The lack of traditional data collection
Traditional data collection is a single source, and the amount of data stored, managed and analyzed is relatively small, mostly handled by relational databases and parallel data warehouses. In terms of parallel computing to enhance data processing speed, the traditional parallel database technology to pursue a high degree of consistency and fault tolerance, according to CAP theory, it is difficult to ensure its availability and scalability.
