graph database

基本解释

There are many use-cases where a graph database is the most natural approach.
在很多种情况下，图形数据库都是最自然的方式。
So unlike other database approaches which only implicitly can form a graph structure a graph database explicitly represents a graph.
所以说，与那些只能间接构成图架构的数据库不同，图形数据库可以明确地表示图。
Unlike other databases which store their data in rows, columns or key-value pairs a graph database stores all information in a network of nodes and edges.
和其他以列、行或者键/值等形式存储数据的数据库不同，图形数据库以节点（Node）和边（Edge）的网络存储所有信息。

Because graphs are extremely flexible data structures, a graph database can emulate any other kind of database.
