Couchebase和MongoDB之间的区别

1. Couchebase：
Couchebase是用于交互式Web应用程序的NoSQL数据库。它是一个易于扩展的数据库，具有高度灵活的数据模型，可提供高性能。
它是两种流行的NoSQL技术的合并：

• (i)内存库–
  它提供了持久性和复制功能，可确保更好的性能。
• (ii)CoucheDB –
  这是一种NoSQL技术，它使用基于JSON的文档对象模型。

2. MongoDB：
它是用C++编写的领先的NoSQL数据库。它基于收集和文档的原理工作，并提供高性能和可伸缩性。它非常易于扩展，并且避免使用复杂的联接。它是一个无模式的数据库，其中每个集合都包含不同的文档。

Couchebase和MongoDB之间的区别：

Couchebase	MongoDB
It has an integrated admin console and everything is configured in a single place.	It follows the master-slave principle and has many parts that are manually configured.
In Couchebase, the data is written in multiple data files which are further organised as B-Trees.	In MongoDB, data is stored in the collection of BSON documents.
It uses the memcached protocol which eleminates the need of an external cache.	It uses external cache in order to handle increased users and scalability.
It can use various tools like REST API, Command line interface or Web UI to handle the maintenance task.	It only supports the CLI tools for maintenance.
A Couchebase bucket does not usually store similar documents.	In MongoDB, the collection may store documents of similar feature.
.Net, Python, Ruby, Scala are some of the programming language that support Couchebase.	C, C++, C# re some of the programming language that support MongoDB.
Couchbase introduced a N1QL – SQL-like query language.	MongoDB uses its own query language that is created with documents in mind.
