BASE (Basically Available, Soft state, Eventually consistent)

BASE is a set of principles for designing distributed databases that prioritize availability over immediate consistency. "Basically Available" means the system responds to most requests, even if some data may be outdated. "Soft state" indicates that the system's data can change over time without each change being instantly reflected everywhere. "Eventually consistent" ensures that, given enough time, all copies of the data will become the same, but immediate consistency isn't guaranteed. This approach helps systems stay responsive and available in large-scale, distributed environments, accepting temporary discrepancies to deliver continuous service.
