This topic describes how to use HoloWeb to create, edit, and delete a schema in Hologres.
Prerequisites
You have logged on to a Hologres instance. For more information, see Log on to an instance.
Manage a schema
To manage a schema, you can refresh information, edit or delete the schema, create
an internal table, create a foreign table, or create multiple foreign tables at a
time.
- Go to the HoloWeb console. On the Metadata Management tab, find the left-side Instances Connected list. All the connected instances are displayed.

manage. All the created schemas are displayed.
Note After you log on to a database, a schema named public is automatically created.
