Pros & cons of SQLite

8 Pros of SQLite

• Lightweight and Small Footprint: SQLite is a compact database engine that requires minimal disk space and memory, making it ideal for embedded systems and mobile applications where resources are limited.
• Zero-Configuration: SQLite does not require any server or setup process. It operates directly on files, which simplifies deployment and administration.
• ACID Compliance: SQLite ensures transactional integrity and reliability through Atomicity, Consistency, Isolation, and Durability (ACID) properties. This makes it suitable for critical applications where data consistency is essential.
• Portability: SQLite databases are platform-independent and can be easily moved between different operating systems and architectures without any modifications.
• Wide Language Support: SQLite has bindings for multiple programming languages, including C/C++, Python, Java, and many more, enabling developers to work with their preferred language.
• Fast Performance: SQLite is optimized for speed and efficiency. It performs read and write operations faster than most traditional databases due to its lightweight design and low overhead.
• Full-Featured Database: Despite its small size, SQLite supports a wide range of SQL features and provides comprehensive functionality, including indexes, triggers, views, and complex queries.
• Open Source and Free: SQLite is open-source software released under the public domain, which means it is free to use and distribute in both commercial and non-commercial projects.

8 Cons of SQLite

• Concurrency Limitations: SQLite is not designed for high-concurrency scenarios due to its file-based architecture. It performs best in single-user or low-concurrency environments.
• No Client-Server Architecture: Unlike traditional databases, SQLite does not have a client-server model. This means it may not be suitable for applications that require multiple simultaneous connections or centralized management.
• Storage Limitations: SQLite has a maximum database size limit, which can be a constraint for certain applications that require storing large volumes of data.
• Less Scalable: While SQLite can handle moderate data loads efficiently, it may face performance degradation with extremely large datasets or high transaction rates.
• Limited Network Support: SQLite does not natively support network connections. To access an SQLite database over a network, additional layers or protocols need to be implemented.
• Less Advanced Security: Compared to some enterprise-level databases, SQLite offers limited built-in security features. It relies on the underlying operating system’s file permissions and lacks advanced access control mechanisms.
• No Stored Procedures: SQLite does not support stored procedures, which are commonly used for encapsulating business logic within the database itself.
• Not Ideal for Client-Server Applications: Due to its file-based nature, SQLite may not be the best choice for applications that require heavy concurrent read and write operations from multiple clients.

Cases when SQLite does not work

1. Large-scale Data Processing: SQLite is not designed for handling large-scale datasets. It performs well with smaller databases that fit within the memory of a single machine. When dealing with a large number of concurrent users or datasets that exceed the memory capacity, other database solutions like MySQL or PostgreSQL may be more suitable.
2. Client-Server Architecture: SQLite works as a file-based database engine, meaning it does not support a client-server architecture. If your application requires multiple clients accessing the database simultaneously or needs to handle concurrent read and write operations, a client-server database system like MySQL or PostgreSQL would be a better choice.
3. High Write Loads: SQLite’s performance can degrade when the database experiences a high volume of write operations. Since SQLite locks the entire database file during write transactions, concurrent writes can result in contention and reduced performance. In scenarios where write-intensive applications are expected, a database system specifically designed for such workloads, such as MySQL or PostgreSQL, would be more appropriate.
4. Distributed Systems: SQLite is not suitable for distributed systems where multiple nodes need to access and update the same database concurrently. Due to its file-based nature, SQLite does not provide built-in mechanisms for replication, synchronization, or distributed transactions. Distributed databases like Apache Cassandra or Apache HBase are better suited for such scenarios.
5. Client-Side Web Applications: While SQLite can be used in client-side web applications through JavaScript or WebAssembly, it may not be the optimal choice for applications that require frequent access to a remote server. In such cases, using a server-side database solution like MySQL, PostgreSQL, or MongoDB, and exposing the necessary APIs can provide better performance and data management capabilities.
