Amazon.com® Database Uses
According to Rick Whiting’s InformationWeek: Amazon.com Database To Cut Lag
Time article (2002), Using Excelon Corp.'s ObjectStore database as a cache-management system,
Amazon cut update time for the web pages from eight hours to two minutes (para. 2).
Amazon uses this specialize commercial object database: ObjectStore, to handle thirdparty retailers pricing and inventory updates upon the marketplace web pages within Amazon’s
web servers. Additionally, different platforms can access the database providing central
configuration of all caches allowing users to change cache behavior. For administration
purposes, optimization, system cache analysis, and central monitoring of all caches became
available. The Cache Management System provides cache sharing between all nodes, and cache
objects cluster-wide invalidation.
Auditability, constant changing landscapes, data security, data recovery, decentralized
data management, increasing data volumes, inefficient use of resources, lack of trained people,
limits on scalability, and low leverage of data assets are possible data management issues.
