Introduction with the advent of the cloud computing era, various types of Internet applications are emerging, the relevant data model, distributed architecture, data storage and other database related technical indicators also put forward new requirements. Although the traditional relational database has occupied the unshakable position in the data storage, but because of its inherent limitation, has been unable to satisfy the cloud computing age to the data expansion, reads and writes the speed, the support capacity as well as the construction and the operation cost request. The era of cloud computing has put forward a new demand for database technology, which is mainly manifested in the following aspects. Mass data processing: to ...

"IT168" I have always felt that nosql in fact very easy to understand, I have also had a very in-depth study of NoSQL, but in the recent preparation of yuntable chart, found that NoSQL not only very profound, 　　And my personal understanding of NoSQL is only superficial, but I am still a "shame and then Yong" people, so after a period of study, from the sixth part of this series, will talk to you nosql, and this article will be the main to do a NoSQL database review. ...

Research on the construction of medical and health data center based on HBase and the synchronization of heterogeneous database Fang Shiwei to determine the data model, this paper puts forward the idea of HBase C-o-r modeling based on the E-R modeling of relational database, Then comprehensive analysis of Health department promulgated medical and Health metadata standards and the actual situation of some health institutions to achieve health information HBase Data Center construction. In order to realize the synchronization of data transparently to data center in heterogeneous relational database of medical institutions, the following schemes are proposed. First of all, in the data format proposed heterogeneous database production ...

In order to implement the National Agricultural Information Conference Spirit, give full play to the central and local information resources advantages, integrate information resources, the national agricultural system to build a unified, shared "National Agricultural Web site information resource Pool", together to create "national information Network" brand-name channel, better for the "three rural" service. Through the construction of "National Agricultural Web site Information resource Database", strengthen the integration of agricultural system information resources, promote the national agricultural information sharing, through the construction of "National Information Network" channel, set up the overall image of the national agricultural Information system, reduce duplication of work, repeat input, improve information services ...

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 ...
