The late 1990s with the rise of Web applications and open-source databases such as MySQL, PostgreSQL, and SQLite, the explosion of user growth. NoSQL databases have been in existence since t
enable users to use their knowledge across systems and to support third-party attachments and tools.3. SQL can be extended, and is versatile and time validated, which can solve problems from fast write-driven transmission to scanning intensive in-depth analysis.4. SQL is an orthogonal form of data rendering and storage, and some SQL systems support JSON and other structured object formats, with better perf
companies may lack DBAs with professional knowledge, and their responsibilities are often represented by system administrators. The complexity of traditional databases has become a bottleneck hindering the company's development.
Everything means that we don't have to use structured data. we are pursuing distributed databases, low latency, and the ability to quickly process massive data.
However, this change is difficult.
: hive is highly-delayed, structured, and analysis-oriented, while hbase is low-latency, unstructured, and programming-oriented. Hive Data Warehouses have high latency on hadoop.
Hbase is located at the structured storage layer, and hadoop HDFS provides hbase with high-reli

Although SQL database is a very useful tool
explanation for NoSQL is "non-relational", and "not only SQL" is also accepted by many people. (The term "NoSQL" was first used in the name of a lightweight relational database in 1998.) )NoSQL
Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to a deluge of research and practice on protocols and algorithms. In this article, I will make some systematic descriptions of the distributed features of the NoSQL database.

Advantages and disadvantages of relational databaseAdvantages:
Can do transaction processing, so as to ensure the consistency of data;
Can be a join, such as multi-table query;
Because of SQL standardization, the cost of data updates is small (the same fields are basically only one place).
Disadvantages:
The write processing of large amount of data is not easy;
If the table data volum
