SQLite and MySQL are both relational database management systems (RDBMS), but they differ significantly in several aspects:
-
Architecture:
- SQLite: It is a serverless, self-contained, zero-configuration, transactional SQL database engine. SQLite stores the entire database in a single file on disk.
- MySQL: It is a client-server database system, meaning it requires a server to manage the database and clients to interact with the server.
-
Scalability:
- SQLite: Suitable for small to medium-sized applications due to its single-file storage and lack of server overhead. It is not ideal for high-concurrency or large-scale applications.
- MySQL: Highly scalable and suitable for large applications with high concurrency requirements. It supports multiple users and complex queries efficiently.
-
Performance:
- SQLite: Generally faster for read operations on small databases due to its simplicity and lack of network overhead.
- MySQL: Offers better performance for write operations and complex queries, especially in multi-user environments.
-
Usage:
- SQLite: Commonly used in mobile applications, embedded systems, and small web applications where a full database server is not necessary.
- MySQL: Widely used in enterprise environments, web applications, and any application requiring a robust, scalable database solution.
Example:
- An Android app might use SQLite to store user preferences and local data because it is lightweight and does not require a server.
- A large e-commerce website might use MySQL to handle customer data, orders, and inventory due to its ability to manage high volumes of data and concurrent users.
