Create Empty database using Oracle Database configuration Assistant

Question

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?

PS: This is how my database tables look like after creating it

Answer 1

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.

Answer 2

I think you have open sample database . Make sure that you have opened database that is create by you.

Adding to @vishad answear.

1. Install SQL Plus, it will ask about password which is needed later
2. Open console and type connect , provide username(system) and password from point 1
3. Create database with commands:

 CREATE USER "YOUR_USER" IDENTIFIED BY superPassword; GRANT "RESOURCE" TO "YOUR_USER" ; GRANT "DBA" TO "YOUR_USER" ; GRANT "CONNECT" TO "YOUR_USER" ; GRANT "EXP_FULL_DATABASE" TO "YOUR_USER" ; GRANT "IMP_FULL_DATABASE" TO "YOUR_USER" ;

4. Connect to database with SQLDeveloper. Defaults are:

 username: YOUR_USER password: superPassword Hostname: localhost Port: 1521 SID: xe
