- Zero Configuration: No setup or configuration is needed, making it simple to integrate.
- ACID Compliance: Supports atomicity, consistency, isolation, and durability for transactional safety.
- Lightweight: Small size and minimal resource usage make it ideal for embedded systems.
Key Features to Look for in SQLite Alternatives
When considering alternatives to SQLite, focus on these key features:
- Scalability: Support for larger datasets and distributed systems.
- Concurrency: Ability to handle multiple read and write operations simultaneously.
- SQL and NoSQL Support: Depending on your application’s needs.
- Advanced Features: Replication, clustering, sharding, and high availability.
