Relative to structured data (the data is stored in the database, it is possible to use two-dimensional table structure to express the implementation data logically, the data that is not convenient to use the database two-dimensional logical table to represent is called unstructured data, including all format Office documents, text, picture, XML, HTML, various kinds of reports, images and audio/ 　　Video information and so on. An unstructured database is a database with a variable field length and a record of each field that can be made up of repeatable or repeatable child fields, not only to handle structured data (such as numbers, symbols, etc.), but also ...

To understand the concept of large data, first from the "Big", "big" refers to the scale of data, large data generally refers to the size of the 10TB (1TB=1024GB) data volume above. Large data is different from the massive data in the past, and its basic characteristics can be summed up with 4 V (Vol-ume, produced, and #118alue和Veloc-ity), that is, large volume, diversity, low value density and fast speed. Large data features first, the volume of data is huge. Jump from TB level to PB level. Second, the data types are numerous, as mentioned above ...

One of the earliest cloud computing inaugural meetings was the Cloud Connect conference in Santa Clara, California. To date, one of the more contentious issues of the conference is "Do not use relational databases to preserve the persistence of data." Known as the "NoSQL" movement, its purpose is to use other forms of databases to process large-scale application data more efficiently. However, I have already published a number of articles on many "large-scale data" that appear in cloud computing. But this sport is more special, it will be to promote data regression ...

Cloud computing, things networking, mobile internet is a popular word in recent years, and these new concepts are emerging, a large number of semi-structured, unstructured data is growing rapidly, pictures, audio videos, social networks and other content filled with the lives of each user.
