This time we do campus video management system, the storage of video used to MongoDB. Compared to storing video in a disk or relational database,

MongoDB stores data and reads more quickly. The following is a general introduction to the macro.

MongoDB is a high-performance, open-source, modeless document-based database that is a popular one in the current NoSQL database. It's in a lot of scenarios

can be used instead of traditional relational databases or key/value storage methods.

---------------------------------------------------------------------------------------------------

NOSQL, the full name is not-only Sql, refers to the non-relational database. The next generation database mainly solves several key points: the non-relational, the distribution

, open-source, level-scalable. The original goal was for large-scale Web applications, which began in early 2009 and typically features applications such as: modulo

Easy replication, simple APIs, eventual consistency (non-acid), high-capacity data, and more. NoSQL is the number key-we use most.

Value storage, and of course other document-type, Columnstore, graph database, XML database and so on.

Advantages of MongoDB

Efficient traditional storage: supports binary data and large objects such as photos or pictures, as well as video.

Automatic sharding to support cloud-level scalability (in the early alpha phase): Auto-sharding supports level DB clusters, dynamically adding amounts

Outside of the machine. (Guaranteed to store large objects, making reading faster).

Large, low-value data: Storing some data with a traditional relational database can be expensive, and before that, many times programmers

Traditional files are often selected for storage.

basic operation of MongoDB
As follows: Insert two data

comparison of MongoDB with SQL

The data in MONGO is the following text view that is stored as a document

After a traditional database is designed to design a table's field and field data type, each record needs to follow a well-designed sheet. In MongoDB is oriented

Documents, each document can have its own number of fields, and each field can have its own data type.
