This article brings you relevant knowledge about MariaDB and MySQL. It mainly talks about the differences between MariaDB and MySQL. Friends who are interested can take a look at it together. I hope it will be useful to you. help.
Introduction to the main differences
Features | MariaDB | MySQL |
---|---|---|
Distribution | MariaDB is a branch of MySQL | MySQL is a product of Oracle Corporation |
Development Company | MariaDB is maintained by the MariaDB Foundation and Community | MySQL is maintained by Oracle Corporation |
Feature Improvements and Enhancements | Performance and Reliability | |
Contains additional storage engines such as Aria, XtraDB, TokuDB etc. | Includes storage engines such as MyISAM and InnoDB | |
MariaDB uses the year and version number as the version naming, such as MariaDB 10.3.8 | MySQL uses major version number, minor version number and revision number as version naming, such as MySQL 8.0.22 | |
Use GNU Universal Public License (GPL) | MySQL uses two licenses: the open source GNU GPL License or the commercial license | |
With MySQL has high compatibility | MariaDB is more compatible than MySQL | |
Supports more programming languages, such as C, Perl, Python, Java, etc. | Support mainstream programming languages, such as C, Java, Perl, Python, etc. | |
Provide better security , such as supporting encryption, safe default settings, etc. | MySQL also provides good security, but the default configuration is looser | |
provided More performance optimization options, such as query optimization, multi-threading, etc. | MySQL also provides a wealth of performance optimization options | |
has Active community support | MySQL's community support is also very active |
It should be noted that although there are many differences between MariaDB and MySQL , they can be used interchangeably in most situations because they have the same SQL syntax and functionality.Incompatible features between the two
- Storage engine: MariaDB contains some storage engines that MySQL does not have, such as Aria, ColumnStore, and MyRocks. These storage engines may not be compatible with MySQL's storage engine.
- Data types: MariaDB contains some data types that MySQL does not have, such as JSON, XML and UUID. If your application relies on these data types, you need to consider whether they are available in MySQL.
- Functions and operators: MariaDB contains some functions and operators that MySQL does not have, such as PCRE regular expressions and BIT_XOR functions. If your application uses these functions and operators, you need to consider whether they are available in MySQL.
- System variables and options: MariaDB contains some system variables and options that MySQL does not have, such as max_statement_time and innodb_adaptive_flushing. If your application relies on these variables and options, you need to consider whether they are available in MySQL.
MariaDB | MySQL | |
---|---|---|
InnoDB | InnoDB | |
InnoDB supports page-level compression with a high compression rate | InnoDB supports row-level compression and the compression rate is low | |
MariaDB has a better caching mechanism and can automatically adjust the cache size as needed | MySQL’s caching mechanism is relatively simple | |
MariaDB supports full-text search index, using the InnoDB engine | MySQL supports full-text search Index, but does not support using | |
MariaDB supports a wider variety of partitioning strategies, such as by month, day, and by key value | MySQL supports relatively few partition strategies | |
MariaDB supports more kinds of backups, including hot backup and incremental backup | MySQL backup is relatively simple | |
MariaDB has better performance in some cases, such as using multiple threads for queries | MySQL may perform better in some cases, such as on certain types of queries |

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

When developing an e-commerce website using Thelia, I encountered a tricky problem: MySQL mode is not set properly, causing some features to not function properly. After some exploration, I found a module called TheliaMySQLModesChecker, which is able to automatically fix the MySQL pattern required by Thelia, completely solving my troubles.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.
