A database management system that primarily relies on main memory for data storage, providing faster data access compared to disk-based databases.
What is In-memory database?
An in-memory database stores data directly in RAM rather than on disk, enabling extremely fast read and write operations. This approach is ideal for applications requiring low-latency performance, real-time analytics, caching, and high-speed transaction processing. Because data is stored in memory, in-memory databases reduce bottlenecks associated with disk access. Examples include Redis, Memcached, and SAP HANA.
