Local Databases
Local databases are data storage systems that run directly on a user's device or local machine, rather than on remote servers. They are designed for applications that need to store and manage data offline, with low latency, or in scenarios where network connectivity is unreliable. Common examples include SQLite for mobile apps and desktop software, and IndexedDB for web browsers.
Developers should use local databases when building applications that require fast data access, offline functionality, or data privacy without relying on a network connection. They are essential for mobile apps (e.g., using SQLite in Android or iOS), desktop software, and progressive web apps (PWAs) that need to cache data locally. This approach reduces server load and improves user experience in resource-constrained or disconnected environments.
