Key concepts

Data structure

MongoDB is a document-oriented NoSQL database. Its data structure consists of fields and values, similar to a JSON object:

{
    "name": "John",
    "sex": "male",
    "age": 30
}

Storage structure

MongoDB organizes data differently from traditional relational databases, using three core units:

MongoDB term	Description	Relational database equivalent
Document	The basic unit of data in MongoDB. A document is composed of BSON key-value pairs.	Row
Collection	A group of documents.	Table
Database	A database can contain multiple collections. You can create multiple databases in MongoDB.	Database

Next steps

Create an ApsaraDB for MongoDB instance. Use the Getting Started guide to create and use an ApsaraDB for MongoDB instance. For more information, see Getting Started. When you create an instance, consider the following deployment aspects:
- Region and zone. The region and zone determine the physical location of your instance and cannot be changed after creation. Select a region and zone based on factors such as your users' geographical location, Alibaba Cloud product availability, application high availability, and private network latency. For more information, see Regions and zones.
  
  For example, if your application is deployed on an ECS instance, create your ApsaraDB for MongoDB instance in the same region and zone to reduce network latency.
- Network planning. After you select a region, you can create a VPC with a custom private CIDR block. Deploy the instance in either the VPC you create or the default VPC. For more information, see Configure a VPC when you create an instance.
Migrate an on-premises MongoDB database to the cloud. ApsaraDB for MongoDB is fully compatible with the MongoDB protocol. Use DTS or native MongoDB tools to migrate your on-premises MongoDB database to the cloud. For detailed instructions, see Data migration and synchronization.
