In order to facilitate understanding, we will simply classify the mainstream NoSQL technologies from multiple dimensions, so that we can have a general understanding of them, in addition, there is a selection standard that can be referenced in actual application scenarios. 1. Data Model refers to the data storage method, which has several schools, such as relations, key values, columns, documents and images. In their respective implementations, relational databases inc

Origins and application scenarios of various database factions Now, we can consider from the perspective of various use cases that the system is suitable for these use cases. What is your opinion? First, we need to look at various data models. The classification methods of these models come from Emil Eifrem and NoSQL databases. Document Database Source: inspired by Lotus Notes.

important NoSQL tools are written in Java. Cassandra, Lucene, Elasticsearch, HBase and neo4j are just some of the most frequently mentioned NoSQL options. Then there are programs like acid-state that use Haskell to write and run in a Java virtual machine. These tools are usually open source and can be easily integrated. Some developers run them independently, and others integrate them into their own modules such as libraries. Either way, Java become
