Next, Wang Shupeng, associate researcher of Institute of Information Engineering, Chinese Academy of Sciences, shared the development and use of new NoSQL large data management systems (BDMS). Wang Shupeng said most of the projects he contacted were non-Internet applications, such as security and transportation. 　　These industries are now faced with big data, but many popular NoSQL databases do not apply to them, so they independently developed a NoSQL database management system. The design of the target system is highly scalable: it can be achieved by increasing the linear branch of the node ...

Guide: The software architect who recently worked for a number of large companies has taken into account the Kristóf Kovács's blog about the mainstream NoSQL database (Cassandra, Mongodb, CouchDB, Redis, Riak, and HBase) in a comprehensive comparison. Although the SQL database dominates 15, it is time to end it. NoSQL in the heyday of today, a variety of nosql products are blossoming, but each ...

Over the past few years, a burgeoning large data-storage mechanism is gobbling up large data-storage markets. This storage solution differs significantly from the traditional RDBMS, which is called NoSQL. The following key members are in the NoSQL world, including Google BigTable, HBase, hypertable Amazon Dynamo, Voldemort, Cassendra, Riak Redis, CouchDB, MongoDB and these solutions ...

NoSQL storage scheme for large scale equipment monitoring data Zhongyu Huang Xiangdong Liu Huangyuxia Tian Wei Wang faced with massive data storage, fast read-write response, large-scale data analysis and other problems encountered in large-scale mechanical equipment monitoring data management, proposed to use based on NoSQL (not only SQL) Laud-ms System for monitoring data management of the storage architecture. A multi-column family free table model is designed, and the performance of reading and writing is analyzed and compared with the theory and experiment, which proves that this storage scheme can solve the storage problem of massive monitoring data and meet the ...

Research on an incremental processing mechanism of parallel data based on NoSQL Huazhong University of Liu Cloud computing has brought new opportunities and challenges to the process of data processing. The traditional relational database is unable to meet the requirement of large data, and the distributed non relational database can satisfy the high concurrency and high demand of reading and writing because of its high reliability and high availability. However, the superior performance of distributed, relational databases is at the expense of SQL data-processing capabilities. Therefore, it is an important research to improve the data processing ability of the non relational database.

In the biomedical field, there are many such data to be dealt with. Wang Yu, associate researcher of the Institute of Health Service and medical information of Military Academy of Medicine, shared the fourth session of China's cloud computing conference.

"51CTO classic" MongoDB and Couchdb are both document-oriented databases that use JSON document formats that are often viewed as NoSQL databases and are now fashionable and have a lot in common, but when it comes to queries, the difference is obvious, COUCHDB requires predefined views (essentially JavaScript mapreduce functions), while MONGODB supports dynamic queries (essentially similar to ad hoc queries on traditional relational databases), and more importantly, when it comes to queries, Co ...

Moving from a relational database to a NoSQL database-for example, from MySQL to couchbase-you need to rethink your data. As for why Couchbase rather than MongoDB, because the author of Bowen Brown is currently vice president of Couchbase, so you know, and this Couchbase blog also relates to the impact of the query after the migration. If you have a database built on MySQL, you may want to consider the need and more important ...

Forbes: hadoop--Big Data tools you have to understand now Apache Hadoop has become the driving force behind the development of the big data industry. Techniques such as hive and pig are often mentioned, but they all have functions and why they need strange names (such as Oozie,zookeeper, Flume). Hadoop has brought in cheap processing of large data (large data volumes are usually 10-100GB or more, with a variety of data types, including structured, unstructured, etc.) capabilities. But this is the same as before ...
