1. 口袋数据库：
PouchDB 是一个开源的 NoSQL 内联数据库。它是在 CouchDB 之后设计的，CouchDB 是一个支持 npm 的 NoSQL 数据库。它是用 JavaScript 语言编写的。由于 PouchDB 驻留在浏览器中，因此无需通过网络执行查询，因此速度非常快。它在浏览器中使用 IndexedDB 和 WebSQL 在本地存储数据。

2. Neo4j ：
Neo4j 是最著名的图形数据库管理系统，它也是 Neo4j, Inc. 开发的 NoSQL 数据库系统。 Neo4j 与 Mysql 或 MongoDB 不同，因为它具有与其他数据库管理系统相比的特殊功能。 Neo4j 以图表的形式存储和呈现数据，而不是表格格式或 Jason 格式。在这里，整个数据由节点表示，在那里您可以创建节点之间的关系，这意味着整个数据库集合将看起来像一个图形，这使其与其他数据库管理系统不同。

PouchDB 和 Neo4j 的区别：

S.NO. PouchDB Neo4j
