4. Base analysis
eBay proposed BASE. eBay services run in a single data center on
a reliable network, deliberately engineered to use potentially stale
or incorrect data, rejecting synchronization in support of faster
response with the risk of inconsistencies [7].
Researchers at Amazon have also adopted BASE. BASE is a
database design philosophy that prizes Availability over Consistency
of operations.
BASE is:
Basically available: The database system always seems to
work. Basically available indicates that the system does guarantee
Availability, in terms of the CAP theorem. NoSQL databases spread
data across many storage systems with a high degree of replication
for high degree of Availability.
