Editor to share with you how to quickly start MongoDB, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

MongoDB is a database based on distributed file storage. Written in C++ language. Designed to provide scalable high-performance data storage solutions for WEB applications.

Step 1: learn the basics

MongoDB is written in the programming languages of CMagneCraft + and JavaScript. It is the fourth largest database management system after Oracle,MySQL and MS-SQL (it has been on the market for 20 to 30 years), and it is one of the most popular file storage databases. MongoDB is known for providing high performance, high availability and easy scalability. It is suitable for many platforms and has many language drivers.

Document-oriented database is a computer program for storing, retrieving and managing document-oriented information. Document-oriented databases are the main category of NoSQL databases. MongoDB is a document-oriented database, which means that all content is retrieved from the database in the form of documents, rather than in the form of behaviors like relational databases.

The documents in the MongoDB database are not commonly used Word or text files, but files in JSON format. MongoDB is a document-oriented NoSQL database.

Step 2: understand the concept

Here are three main concepts that describe what document-oriented databases include:

(1) Database: MongoDB arranges data, just like most relational databases. In RDBMS (Relational Database Management system), a database is a set of tables, stored procedures, views, etc. In MongoDB, a database is a set of collections. The MongoDB database contains one or more collections.

(2) Collection: this collection is equivalent to the RDBMS table. Documents in a collection can have different fields. In general, all documents in the collection have similar or related uses.

(3) File: the records in the MongoDB collection and the basic data units in MongoDB are documents. The document contains a set of fields or key-value pairs. The best way to think about this is that it is similar to a multidimensional array.

Step 3: learn basic utilities / tools

MongoDB tools and processes interact primarily with running MongoDB instances. These processes not only create traffic on the running database instance, but also force the database to read all data through memory. Each of the following tools is designed for a specific purpose to meet the needs of various functions in a document-oriented database:

Mongo: this is Mongo's interactive shell that allows database administrators to view, insert, delete, and update data in the database, get replication information, set shards, shut down the server, perform JavaScript, and so on.

Mongostat: a command-line tool, mongostat displays a summary list of statistics about the status of currently running MongoDB instances.

Mongotop: another command-line tool, mongotop provides a way to track when MongoDB instances read and write data.

Mongoimport,mongoexport: these command-line utilities create binary exports of the contents of the Mongo database.

Step 4: explore the main features

MongoDB has many important functions, making it the preferred database for modern Web application development. The following features represent some of the main functions provided by the database:

Supports indexing, ad hoc query and real-time aggregation. MongoDB supports ad hoc queries by indexing BSON documents and using a unique query language. It creates indexes to improve search performance. These features provide powerful ways to access and analyze data.

Replication is supported. MongoDB supports two forms of replication: replica set and master-slave replication. Replication capability is important because it constantly replicates data from the primary server to the secondary server. Therefore, if the primary server fails, the secondary server can take over.

Based on hash distribution. This feature applies when different parts of the data table are distributed across multiple servers. It distributes new entries on all available servers, making the data more evenly distributed. This solves a major and common problem: scaling. This feature is particularly important for large datasets and high-throughput operations.

file store. This feature, called GridFS, is a simple file abstraction. GridFS is basically a way to decompose large binary objects stored in a database. It requires two queries: one to get the metadata of the file and the other to get its contents. Therefore, if an organization uses GridFS to store small files, its application must double the number of queries it must execute. As a rule of thumb, anything too big to load right away may not be what the organization wants to load on the server right away. Therefore, any content that an organization plans for data flow transmission is a good choice for GridFS.

MongoDB Management Service (MMS). This feature is a truly unique product because it represents a simple approach to operations that are often too complex. Now, with a single click, you can configure the machine and configure the replica set and upgrade in a single interface.

Step 5: make the appropriate upgrade

It is important to upgrade MongoDB to the latest version, as older versions may accumulate several security issues over time. Failure to apply updates may make the organized data unprotected and vulnerable to hackers. Always install the latest version, as doing so will be a more secure way to make your organization's document-oriented database more secure. The latest version as of December 2016 is 3.4.1.

Getting started with MongoDB is easy, but once the application is built, organizations may find more complex challenges. Avoid deviating too far before starting to think about the right design, optimization, and implementation. The application of MongoDB is increasing day by day, so it is very important to have a clear understanding of the basics before applying it.
