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.

  • A data connection has been created. For details, see Creating a Data Connection.

  • MRS API connections cannot be used to manage databases in a visualized mode. You are advised to create a database using SQL scripts.

  • Before deleting a database, ensure that the database is not in use and is not associated with any data tables.
