MEMSQL and NOSQL database are similar to comparison

MEMSQL and NOSQL database are similar to comparison Memsql and NOSQL are important parts of modern database technology, and they have obvious differences in data storage and operation methods.This article will compare the similarities and differences between MEMSQL and NOSQL databases, and provide the necessary programming code and related configuration descriptions. 1. The common points in common 1. Support large -scale data storage: MEMSQL and NOSQL databases can store large -scale data, and can easily expand to adapt to growing data volume. 2. High scalability: Both databases have good scalability, and can increase processing capabilities by adding new nodes or servers to cope with high loads. 3. High -performance data operation: both MEMSQL and NOSQL database can provide fast data operations, with the characteristics of high throughput and low latency. 2. The characteristics and advantages of MEMSQL 1. Relational database: MEMSQL is a distributed relationship database that supports SQL query language.It has standard ACID characteristics and can ensure the consistency and reliability of data. 2. Memory and disk storage: MEMSQL stores data in memory to achieve high -speed data reading and writing operations.At the same time, it also supports data persistence storage to the disk to ensure the durability and reliability of the data. 3. Real -time data processing: MEMSQL has the ability to process real -time data, which can quickly extract, analyze and apply data from high -speed data streams, and generate reports or trigger corresponding business logic in real time. Related configuration description: The following is an example of using MEMSQL for data storage and query. 1. Installation and configuration MEMSQL: # Download Memsql installation package wget https://download.memsql.com/memsql-7.2.2/memsql-7.2.2.tar.gz # tar -xvf memsql-7.2.2.tar.gz # Enter the directory after decompression cd memsql-7.2.2/ # Run the installation command for Memsql installation ./install.sh --local 2. Create a database and table: # To Memsql Shell memsql> connect 'root'@'127.0.0.l'; # Create a database memsql> create database mydb; # Switch to the database memsql> use mydb; # Create a table memsql> create table mytable (id int, name varchar(50)); 3. Insert and query data: # Insert data memsql> insert into mytable values (1, 'John'); # Query data memsql> select * from mytable; Third, the characteristics and advantages of NOSQL 1. Non -relational database: NOSQL database uses non -relational data models, such as key -value pairs, documents, columns, or graphics models, providing more flexible data organization methods. 2. Distributed architecture: The NOSQL database can be expanded horizontally to multiple servers, which improves availability and performance through data shards and automatic copying. 3. No fixed mode: The NOSQL database does not need to define the table structure in advance. You can dynamically add fields according to the data needs, making the data mode change more flexible. Related configuration description: The following is an example of using the NOSQL database for data storage and query. Take MongoDB as an example. 1. Installation and configuration mongodb: # Add mongodb source sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10 echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list sudo apt-get update # Install MongoDB server and client sudo apt-get install -y mongodb-org 2. Create a database and collection: # To MongoDB Shell mongo # Create a database > use mydb; # Insert data > db.mycol.insert({"name": "John"}); 3. Query data: > db.mycol.find(); This article introduces the similarities and differences between MEMSQL and NOSQL databases, as well as their characteristics and advantages.At the same time, the example code and related configuration descriptions of data storage and query using MEMSQL and NOSQL databases are provided for readers for reference and learning.
