Nosql Paper

With the development of data services and NoSQL databases, Web applications increasingly need NoSQL databases, and now it seems that NoSQL databases have a tendency to break traditional relational databases. In December last year, couchbase a http://www.aliyun.com/zixun/aggregation/32268.html "> survey showed that many companies are ready to adopt NoSQL technology over the next year." But why did they deploy NoSQL? Why they give up ...

Type selection and design of bigtable NoSQL database release time: 2012.04.16 14:20 Source: Blog Author: Blog This paper introduces the selection strategy and schema design principle of Bigtable/hbase type NoSQL database system. Data scale BigTable Class database system (Hbase,cassandra, etc.) is to solve ...

A brief analysis of the relationship between NoSQL technology and database teaching in the field of database, Lou Ying relational database occupies a dominant position for a long time, which is always the main content of database course. With the rise of Web2.0, the technology of NoSQL (non relational database) has been widely used in the environment of massive data, which has exerted a strong influence on the development of database technology, and has exerted a far-reaching influence on the teaching of the current database course. This paper probes into the NoSQL technology and its main characteristics, analyzes the challenge of the NoSQL technology to the database teaching, and the relation database and n ...

Research and application of large data query technology based on NoSQL database Zhu Jianseng Wang Jianxiong Zhang Junfeng based on NoSQL database theory, according to the different application scenarios, the NoSQL database is divided into high performance read-write, Document-oriented and distributed-computing-oriented 3 types. Comparing and analyzing the advantages and disadvantages of the 6 representative products of these 3 types of databases, combined with the requirement of large data operation in the comprehensive analysis system of ticketing information for railway tickets, the paper chooses C ...

Research on NoSQL database security based on Hadoop Shanghai Jiao Tong University Chapin This paper first analyzes the key theory and technology of NoSQL database, according to the characteristics of the lack of security of the current NoSQL database products, based on the confidentiality, integrality, usability and consistency of the database, combined with the distributed characteristics, The user security requirements of NoSQL database are analyzed and defined from internal and external. Then, through the source analysis of Hadoop and hbase, this paper studies the security mechanism of Hadoop platform and HBase database.

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 ...

Recently, Thumbtack published two papers, namely ultra-high performance NoSQL benchmark and nosql failover characteristics, the former is the analysis of durability and performance trade-offs, the latter is about Aerospike, Cassandra, Couchbase and MongoDB several NoSQL fault-transfer features. All two benchmarks try to test "user-oriented applications with high throughput and low latency requirements, which can be stored using key-value forms." To make a thumback.

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 ...

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.

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 ...
