1.德比:
Derby 是一个用Java实现的功能齐全的开源关系数据库管理系统 (RDBMS),顾名思义,它是由 Apache Software Foundations 开发的。它基于Java、JDBC 和 SQL 标准。 Derby 易于安装、部署和使用。它要么嵌入到Java应用程序中,要么用作数据库服务器。

2. MongoDB:
MongoDB 是一个跨平台的面向文档的非关系型(即 NoSQL)数据库程序。它是一个开源文档数据库,以键值对的形式存储数据。 MongoDB 由 MongoDB Inc. 开发,最初于 2009 年 2 月 11 日发布。它是用 C++、Go、JavaScript、 Python语言编写的。 MongoDB 提供高速、高可用性和高可扩展性。
