Creating a Database
After creating a data connection, you can create a database on the console or using a SQL script.
- (Recommended) Console: You can directly create a database on the DataArts Studio DataArts Factory console with no code.
- SQL script: You can also develop and execute a SQL script for creating a database in the SQL editor of DataArts Studio's DataArts Factory module or a data lake product, and then use the script to create a database.
This section describes how to create a database on the DataArts Factory console.
Prerequisites
- You have already enabled the corresponding cloud services. for example, the MRS service.
- A data connection has been created. For details, see Creating a Data Connection.
