[Learning MongoDB step by step]-Brief Introduction to MongoDB (1), brief introduction to mongodb

In the previous blog, we spoke about NoSQL. We have a comprehensive understanding of NoSQL. Starting from this blog, we will take everyone into the MongoDB world. Next we will introduce MongoDB.

 

What is MongoDB?

 

Let's look at the most authoritative explanation on the official MongoDB Website: MongoDB (from "humongous") is an open-source document database, and the leading NoSQL database. Written in C ++.

Translation: MongoDB is named "humongous" (I don't know what it is). It is an open-source, document-oriented database and a leading non-relational database. MongoDB is written in C ++,

 

MongoDB is a cross-platform, document-oriented database that provides high performance, high availability, and easy scalability.

 

 

Why use MongoDB?

 

1. Document-Oriented Storage (Document-Oriented Storage)

2. Full Index Support (Indexable for any attribute)

3. Replication & High Availability (Replication and High Availability)

4. Auto-Sharding)

5. Quering (rich queries)

6. Fast In-Place Updates (Fast update)

 

Advantages of MongoDB over RDBMS

 

1. Architecture: MongoDB is a document-type database, where a collection stores different files. The number of fields, the content and the file size can be different from copying from one file to another.

2. A single object has a clear structure.

3. No complex connections

4. Deep query capability. MongoDB supports dynamic query using a document-based query language, which is almost as powerful as SQL.

5. Optimization

6. Easy scale: MongoDB is easy to scale

7. Application Object conversion/ ing of database objects is not required

8. Use internal memory storage (window) workgroup to achieve faster data access

 

Any relational database has a typical architecture design that shows the relationship between tables and these tables. Although there is no relation in MongoDB.

 

Under what circumstances does MongoDB use?

 

1. Big Data

2. content management and delivery

3. Mobile and social networking infrastructure

4. User Data Management

5. Data Platform
 

Summary
 

MongoDB is a pioneer in non-relational databases and has epoch significance. Next we will introduce how to download and install MongoDB.
