SQLite
Contained under C programming library, SQLite works as a relational database management system the system is embedded into the end programme rather than being a client server database engine.
SQLite is widely recognized as the most deployed database engine, making it a popular choice for embedded database software, particularly in applications that require client or local storage. This versatility allows SQLite to be seamlessly integrated into various application software, such as web browsers, where it efficiently manages local data. Many widely used browsers and embedded systems, including mobile phones and operating systems, rely on SQLite’s implementation of SQL for their database management needs. Its lightweight nature and ease of integration make it an ideal solution for these environments, where resource efficiency and reliability are crucial.
It works in collaboration to various programming languages.
Frequently Asked Questions
SQLite is serverless, meaning it doesn’t require a separate server to run. It is also zero-configuration, which means that no setup or administration is required. SQLite databases are stored in a single cross-platform disk file, making it portable and easy to use for small to medium-sized applications.
SQLite is commonly used in embedded systems, mobile applications (like Android and iOS apps), web browsers, and small to medium-sized desktop applications. It is ideal for applications that need a lightweight database or those that don’t require the complexity of a full-scale relational database management system (RDBMS).
SQLite is secure, but its security depends on how it is used. For instance, SQLite offers features like encryption (with extensions like SQLite Encryption Extension) and access controls to secure data. However, since SQLite databases are file-based, the security of the database file (like file permissions) is crucial.
SQLite is not designed for high-concurrency environments with many simultaneous users writing to the database. It has a write limit because it locks the entire database during write operations. Also, it might not be suitable for very large databases, as its performance can degrade as the database grows.
SQLite can handle databases up to 281 terabytes, but its performance might not be optimal for very large datasets. It is generally recommended for smaller applications where the database size doesn’t exceed a few gigabytes.
Backing up an SQLite database is straightforward. You can simply copy the database file to a secure location. Additionally, SQLite provides a VACUUM command to clean up and optimize the database, which can also be used to create a fresh backup.
Yes, SQLite is ACID-compliant, meaning it adheres to the principles of Atomicity, Consistency, Isolation, and Durability, which are essential for reliable transactions in a database system.
SQLite can be used in a Python application using the built-in sqlite3 module. You can connect to a database, execute SQL commands, and fetch results using Python’s standard database API.
