Before you can use an ApsaraDB RDS instance, you must create a database on the instance. This topic describes how to create a database on an ApsaraDB RDS for PostgreSQL instance.
- Instance: a virtualized database server, on which you can create and manage a number of databases.
- Database: a set of organized data that can be shared by a number of users. A database provides the minimal redundancy and is independent of applications. You can consider a database to be a warehouse that is used to store data.
- Character set: a collection of letters, special characters, and encoding rules that are used in a database.
- You can create and manage RDS instances in the ApsaraDB RDS console.
- Before you can migrate data from an on-premises database to an RDS instance, you must create a database and an account on the RDS instance. Make sure that the created database has the same properties as the on-premises database. In addition, make sure that the created account has the same permissions on the created database as the account that is authorized to manage the on-premises database.
- Access RDS Instances, select a region at the top, and then click the ID of the target RDS instance.
- In the left-side navigation pane, click Databases.
- Click Create Database.
- Configure the following parameters.
Parameter Description Database Name
- The name of the database can contain up to 63 characters in length.
- The name of the database can contain lowercase letters, digits, hyphens (-), and underscores (_).
