Before you start to use ApsaraDB RDS, you must create databases and accounts on your RDS instance. This topic describes how to create a database on an ApsaraDB RDS for PPAS instance.
Prerequisites
Terms
- Instance: a virtualized database server, on which you can create and manage a number of databases.
- Database: a set of data that is stored in an organized manner and can be shared by a number of users. A database provides the minimal redundancy and is independent of applications. In simple words, a database is a data warehouse that is used to store data.
- Character set: a collection of letters, special characters, and encoding rules that are used in a database.
Precautions
- Databases on the same RDS instance share all of the resources that belong to the instance. You can create and manage a number of databases on your RDS instance by using SQL statements.
- If you want to migrate data from an on-premises database to your RDS instance, you must create a database and an account on your RDS instance. The database and the account must have the same names as the on-premises database and its authorized account.
