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.
