SQLite3 and MySQL Database Features and Differences

Whether we are using databases for business or daily performance comparison database selection, it is inevitable to see SQLite3 and MySQL databases. In fact, we use more of the latter. After all, there are more network wide document resources and program resources provided, but SQLite3 also has its own characteristics. In this article, we will simply sort out SQLite3 and MySQL databases to see the characteristics and comparative concepts of the two databases.

 SQLite3 and MySQL Database Features and Differences

First, concept comparison between SQLite3 and MySQL

1、SQLite3

SQLite3 is a lightweight embedded database, which is suitable for local storage solutions of small projects. It does not need to install and configure the server, so it has good portability. SQLite3's SQL syntax is relatively simple and does not support advanced features such as stored procedures and triggers. It is simple, easy to use, lightweight, and suitable for small applications and mobile applications.

2、MySQL

MySQL is a powerful relational database management system, which is suitable for large-scale applications, such as Web applications, enterprise applications, etc. It supports complex query and transaction operations, and is characterized by high performance, high concurrency, and good scalability. MySQL's SQL syntax is complex, and supports most SQL standards and some advanced SQL features, such as stored procedures and triggers. It is characterized by high performance, powerful functions, and good scalability. It is suitable for application scenarios that need to handle large-scale data, high concurrent access, and complex query and transaction operations.

Second, the difference between SQLite3 and MySQL

1. Deployment and configuration

SQLite3 does not require an independent server process and configuration, while MySQL needs to install and configure the server.

2. Concurrency support

MySQL supports concurrent connections and multi-threaded write operations, while SQLite3 only supports multiple read operations.

3. Scale and performance

MySQL is suitable for processing large databases, providing higher performance and scalability, while SQLite3 is suitable for small projects or embedded systems.

4. Functional richness

MySQL provides more advanced functions and extension options, while SQLite3 has simpler functions.

5. Dependencies

SQLite3 is a zero configuration, serverless database system that does not require other dependencies, while MySQL needs to be installed and configured independently.

Third, suggestions for selecting SQLite3 and MySQL

SQLite3 and MySQL have their own advantages and disadvantages. Which database you choose depends on your specific needs and application scenarios. If you need a lightweight embedded database or a local storage solution suitable for small projects, SQLite3 is a good choice; If you need to handle large-scale data, highly concurrent access, and complex query and transaction operations, MySQL may be more suitable.
