LevelDB

LevelDB is a fast, lightweight database system developed by Google that stores data in key-value pairs. Think of it like a digital filing cabinet where each piece of data has a unique label (key) and the corresponding information (value). It's designed for high performance and simplicity, making it ideal for applications that need quick data access without requiring complex database features. LevelDB manages data efficiently on disk, providing fast read and write operations, making it suitable for embedded systems, mobile apps, and other scenarios where speed and resource efficiency are important.
