Creating a new DB in Oracle?

Question

Oracle

Previously worked with SQL SERVER and the creation of a new database was achieved by calling the CREATE DATABASE command.
Now here I get acquainted with Oracle.
I correctly understand that in Oracle this is done through the DataBase Configuration Assistant? Is it normal that a new database is being created so slowly? In MS SQL, everything was done instantly.

Answer 1

iluxa1810 , DBCA creates a new instance of the database, with its own data files, its own system dictionary.
You can read about comparisons of concepts, for example, here itech-notes.blogspot.ru/2012/10/oracle-ms-sql-serv...
According to this link, the database in SQL Server corresponds to the schema in the Oracle database, and the schema is the objects of a specific user.
That is, you can have one instance (all database files) and one database instance (memory structures), in which several schemas (users) will be created with the same set of tables, procedures, packages, and so on.
