Undoubtedly, the management of big data is now a hot topic in the enterprise development community. But why the discussion of big data has become a popular phenomenon will appear so late? Why has big data processing been not part of an enterprise toolset for so long? Does this mean that today's information technology ecosystem makes big data solutions as smart as they are today? One of the key reasons why big data management is so hot nowadays is that most organizations have to manage the growing volume of data that they handle. From the Internet ...

A survey of data representation and compression in graphs Tommy Yan bear Jia Liu Guo Li the efficient, compact representation and compression of graph data containing billions of nodes and edges is the basis of large-scale graph data analysis and processing. Graph data compression technology can effectively reduce the storage space of graph data, Fast access is also supported on graph data in the form of compression. By analyzing the present situation of the technology, this paper divides the technology into two kinds: compression technology based on traditional storage structure, compression technology of Web page image, compression technology of social Network Diagram, compression technology for specific query, 4 categories. Detailed classification of each type of technology ...

Research on cloud Data Management index technology the explosive growth of Ma Youzhong Mengxiao data poses great challenges to traditional relational databases, so that it has encountered the bottleneck in the aspect of expansibility, fault tolerance and so on. Cloud computing technology relies on its high scalability, high availability, fault tolerance and other features to become a large-scale data management effective solution. However, the existing cloud data management system also has deficiencies, which can only support the fast query based on the primary key, because of the lack of indexes, views and other mechanisms, so can not provide efficient multidimensional query, join and other operations, which limits the cloud computing in ...

Large data GIS Li Qingquan deren Large data not only makes the world realize the importance of data, but also causes many industries to change radically. The large data age also presents many challenges to GIS, such as the storage and management of massive, multi-source, heterogeneous data, and the value mining in the face of a lot of noise. As an important tool for spatial data management, analysis and visualization, GIS must be changed and adjusted in large data age to meet the needs of large data. This paper analyzes the challenges of traditional GIS in the light of several "V" characteristics of large data, and studies the basic ...

Scache is a different method of PHP session data management. It provides a common key-value data cache for transient session data storage. Scache also provides a shared key space, shared counters, and simple caching capabilities. Scache distinguishes the other implementations from a tree-like key space, where people can easily manipulate the parts that are required to store session data and the data groups stored in the entire subtree that expire. Scache stores all session data inserts until the data is corrupted, thus reducing the redundant storage of the same data in other ...
