摘要：之前收集了一些存储产品，最近又重新整理了一下，对他们进行了简单的分类。每个对存储的分类可能不仅相同，我的分类完全按照自己的喜好来分，如和您的分类不同，仅供参考。只是做了搜集和分类，少量产品加了写介绍，希望以后有时间，加更多更详细的介绍。

1.存储引擎

1.1 Hash Table

1.1.1 dbm (database manager)

https://en.wikipedia.org/wiki/Dbm

The dbm library stores arbitrary data by use of a single key (a primary key) in fixed-size buckets and uses hashing techniques to enable fast retrieval of the data by key.

1.2 btree

1.2.1 berkerlydb

https://en.wikipedia.org/wiki/Berkeley_DB

http://baike.baidu.com/view/1281930.htm

Key/value数据模型

Berkeley DB最初开发的目的是以新的HASH访问算法来代替旧的hsearch函数和大量的dbm实现（如AT&T的dbm，Berkeley的 ndbm，GNU项目的gdbm）

1.2.2 LMDB (Lightning Memory-Mapped Database)

LMDB is a Btree-based database management library modeled loosely on the BerkeleyDB API, but much simplified. The entire database is exposed in a memory map, and all data fetches return data directly from the mapped memory, so no malloc's or memcpy's occur during data fetches.
