Db Storage

Berkeley DB (LIBDB) is an industry-leading open source, embedded storage engine that provides embedded databases that support traditional client/server applications. It includes B + trees, queues, extended linear hashes, access methods for fixed and variable length records, processing, locking, logging, shared memory caching, database recovery, and synchronization of highly available systems. DB supports C, c+, C #, Java, PHP, and Perl APIs. It supports data in key-value pairs (NoSQL), SQL, and Java object formats. It is suitable for ...

There are two main ways to store data: Database and filesystem, and the object-oriented storage are developed behind, but the overall thing is to store both structured and unstructured data. DB is initially serviced for structured data storage and sharing. FileSystem storage and sharing is large files, unstructured data, such as pictures, documents, audio and video. With the increase in data volume, stand-alone storage can not meet the needs of structured and unstructured data, then in the era of cloud computing, there is a distributed ...

A data storage technology of map tile based on NoSQL Chen, Liang, Hao Wen, Juagen, Li Yuxiang, Shu Fangfibenwen Firstly, this paper introduces the origin and development of NoSQL (non relational database), compares the advantages and disadvantages of the relational database, and puts forward the storage strategy of map tile data based on NoSQL. The difference between the MONGO DB and SQL Serv-er 2000 in the storage and concurrent access performance of the NoSQL database products oriented to document is analyzed by experiment. The results show that the Mongo db in the mass space number ...

Study on elastic control of multi-tenant data storage System in cloud Shandong University Huliansu This article focuses on metrics related to data access time. The above two conditions should be ensured in the data elastic control, which increases the difficulty of the elastic control. 2 in order to achieve the flexible control of a multi-tenant storage system, we need to be able to propose control strategies to determine which data to move and where to move. Large-scale application load fluctuation, adaptive load balancing requirements can be scale-out at peak load, load low peak scale-down. This moves through data (for example, PA ...).

Recently focused on Hadoop, so I've also been looking at Hadoop related projects.        HBase is an Open-source project based on Hadoop and an implementation of Google's bigtable. What is BigTable? Google's monitors the full explanation. Literally is a big table, in fact, and we imagine the traditional database table is still somewhat different. Loose data can be said to be between M ...
