Confusion over user and schema

Question

now my problem is that i created user but its not getting reflected in the schema
shouldnt the schema get created automatically
i am confused what should i check for

hello,
First of all you should know the terminology.
Schema -> Collection of objects (Tables, Views, Indexes, Sequences etc.,)
Example: Scott/tiger (Is a sample oracle user) In database terminology it is named as Scott's Schema.
When you create a new user in oracle the user would be empty with no objects. Unless you have previleges to create objects.
