I am using Oracle's Database Configuration Assistant tool to create a new database but once the database is created, I open it in Oracle SQL Developer, I see a lot of tables already created. Why is that? How can I create an empty database?
P.S: This is how my database tables look like after creating it
I think there is some confusion between schema and databases.
You can never create an empty database in Oracle, since when you create a database in Oracle with DBCA tool, it creates some pre-seeded sample schemas and some System schemas with system tables.
You can create an empty schema using the CREATE SCHEMA
command, after the database is installed.
