What are the features of SQLite database?
SQLite is a type of embedded relational database management system, with the following characteristics:
- Lightweight: The core library of SQLite is very small, only a few hundred KB, making it suitable for use on resource-limited embedded devices. As a result, it has very low storage space and memory consumption.
- Serverless: SQLite stores data in the host file system, without a separate server process. This makes it incredibly easy to deploy and use, without the need for configuring and maintaining a database server.
- Zero configuration: SQLite does not require complex configuration and management, there is no need to set up users, permissions, or network connections. Just operate on the database file within the application.
- Single user: SQLite is a single-user database, meaning only one process can access it at a time. This requires additional synchronization mechanisms when using SQLite in a multi-threaded or multi-process environment.
- Transaction support: SQLite provides support for ACID (Atomicity, Consistency, Isolation, and Durability) transactions, ensuring data integrity and consistency.
- Cross-platform: SQLite is compatible with various operating systems, including Windows, Mac, Linux, and embedded devices. This makes it easy to migrate SQLite databases to different platforms for use.
- SQL Compatibility: SQLite supports most standard SQL syntax and operations, allowing users to perform common data queries, insertions, updates, and deletions using standard SQL commands.
- Embeddability: SQLite can be embedded as a library in an application, allowing the application to access and manipulate the SQLite database directly through an API without needing to communicate with the database through a network or other means.
- No internet dependency: Since SQLite is a local database, it doesn’t require a network connection and can be used in offline environments.
In general, SQLite is characterized by its simplicity, lightweight, ease of use, flexibility, and cross-platform compatibility, making it suitable for applications that require a lightweight database solution.
