Description
Technical Field
The invention relates to the field of data analysis, in particular to an abnormal environment real-time monitoring system.
Background
The purpose of data analysis is to concentrate and extract information hidden in a large collection of seemingly chaotic data, so as to find out the intrinsic laws of the studied objects. In practical applications, data analysis may help people make decisions in order to take appropriate actions. Data analysis is a process of organizing and purposefully collecting data and analyzing the data to make it information. This process is a support process for quality management architectures. Data analysis processes need to be applied appropriately throughout the life cycle of the product, including various processes from market research to after-market service and final disposal, to promote effectiveness. For example, a designer analyzes the obtained data to determine a design direction through extensive design investigation before starting a new design, and thus data analysis is extremely important in industrial design.
Offline data analysis is used for more complex and time-consuming data analysis and processing, and is generally built on a cloud computing platform, such as an open-source HDFS file system and a MapReduce operation framework. The Hadoop cluster comprises hundreds or even thousands of servers, stores PB or even tens of PB data, runs thousands of offline data analysis jobs every day, processes hundreds of MB to hundreds of TB or even more data for each job, and has a running time of several minutes, hours, days or even longer. Online data analysis, also known as online analytical processing, is used to process a user's online requests and has a relatively high demand for response time (typically no more than a few seconds). In contrast to offline data analysis, online data analysis can process a user's request in real time, allowing the user to change the constraints and limitations of the analysis at any time. Online data analysis can handle much smaller amounts of data than offline data analysis, but with advances in technology, current online analysis systems have been able to handle tens of millions or even hundreds of millions of records in real time. The traditional online data analysis system is built on a data warehouse taking a relational database as a core, and the online big data analysis system is built on a NoSQL system of a cloud computing platform. If online analysis and processing of big data are not available, huge internet web pages cannot be stored and indexed, so that an existing efficient search engine cannot be provided, and the vigorous development of microblogs, blogs, social networks and the like built on the basis of big data processing cannot be realized.
