MongoDB与PostgreSQL

MongoDB和PostgreSQL是用于企业应用程序的两个最标准的数据库。尽管两个数据库都是开源的，但它们也有一些区别。

在本节中，我们将基于各个方面来讨论MongoDB与PostgreSQL数据库系统之间的区别。

什么是MongoDB?

它是一个面向文档的，跨平台的开放源代码数据库，并使用C++编程语言编写。它用于提供大量数据存储，丰富的查询语言，高性能和高可用性。

使用该数据库的主要目的是易于使用和理解大数据支持，快速的开发功能以及灵活的部署。 MongoDB由10gen公司(称为MongoDB Inc)建立和维护。开发人员可以轻松理解和使用它，并且数据以类似JSON的格式存储。

它被开发用于收集和文档概念。它是一个跨平台，这意味着它支持各种操作系统，例如Linux，Windows，MacOS等。使用Java ， Node.js ，C， PHP ，C++， Python和Ruby等不同的编程语言。

什么是PostgreSQL?

PostgreSQL是最流行的对象关系数据库管理系统，用于管理关系数据库并安全地存储它。它是一种开源数据库软件，用C编程语言编写。

PostgreSQL遵循事务以及ACID(原子性，一致性，隔离性和持久性)属性。它支持各种操作系统，例如Microsoft Windows ，UNIX，Mac OS X， LINUX等。

它是提供多版本并发控制(MVCC)功能的初始数据库。

让我们看一下MongoDB与PostgreSQL之间的一些本质区别，这将有助于我们增强知识：
