big data architecture patterns

Tags: blog http using strong data OSHttp://blog.sina.com.cn/s/blog_7ca5799101013dtb.htmlAt present, although big data and database all are very hot, but quite a few people can not understand the essential difference between the two. Here's a comparison between big data techn

In today's enterprises, 80% of the data is unstructured data, which increases by 60% every year. Big Data will challenge enterprises' Storage Architecture and Data center infrastructure. It will also trigger a chain reaction to ap

abnormal value is an object that seriously deviates from the total average value of a dataset or a data combination. This object is far from other objects in the dataset. Therefore, the appearance of abnormal values indicates that a system problem occurs and needs to be analyzed separately. P Pattern Recognition-uses algorithms to identify patterns in data and

collect information from other sources, including mobile applications, sensors, websites, clickstream data, and social media activities. The data can be converted into products. It is not easy to collect and analyze large amounts of data, especially unstructured data. Currently, enterprise systems cannot process TB o

As a data analyst, can you predi

Excerpted from Chapter 14 "Big Data daily notice: Architecture and algorithms", the book directory is here for massive data to be mined, in a distributed computing environment, the first problem is how to evenly distribute data to different servers. For non-graph

nodes and output functions to form a logical strategy, this talk about its principle, mainly through the case of the way to explain the R language implementation of neural network algorithm process and attention to matters.Main cases:Case 1: Analysis and prediction of the quality and type of alcohol in the neural network;Case 2: Corporate financial early warning model. Nineth Lecture : Cross-validation compares each modelFor the same data, there may

The big data architecture and platform are new things and are still developing at an extraordinary speed. Commercial and open-source development teams release new features on their platforms almost every month. Today's big data clusters will be significantly different from t

big, if continue to process the data according to the C/S mode, can not adapt to this huge data processing requirements, but also the cost of equipment procurement and operating costs of pressure, there is an urgent need to change the system operation mode, redesign system architecture. In this way, the concept of nod

business chain of traditional bi is compressed as much as possible. The integration of data acquisition and analysis results can be implemented in both electronic and self-service channels (e.g., product correlation recommendations based on customer personality, real-time pricing based on scenarios, personalization of self-service device interfaces, etc.), as well as the application of big

specifically matches instant queries. Real-time queries typically use the architecture of the MPP (massively Parallel processing), so users need to choose between Hadoop and MPP two technologies. In Google's second wave of technology, some of the fast-track SQL access technologies based on the Hadoop architecture have gradually gained people's attention. There is now a new trend in the combination of MPP a
