database - 哪些数据库可以让您对数据进行操作？

Question

我喜欢redis。它有字符串、列表、集合等等。我查了一下couchdb，认为它很相似，但事实并非如此。Redis 允许我对数据进行操作，例如 incr、推送/弹出列表、从 ? 获取列表项？到?等

还有哪些其他数据库允许我对数据进行类似的操作？

Answer 1

I can think of MongoDB, it supports atomic operations like inc,push,set,unset etc. on the data. A complete list is given at: www.mongodb.org/display/DOCS/Atomic+Operations Next release (v2.2) of MongoDB has aggregation framework built into it, then you can do operations like: avg, more info at: http://docs.mongodb.org/manual/applications/aggregation/
