        Planning

        I have a software package running
        named Oracle this is my Database Server
        this runs on a computer also called a server
        
        the Oracle instance running is Oracle 19 C
        
        I will need access to this server this means I will need:
        
        A) the Server URL
        B) a valid User Id
        C) a valid Password
        
        Next I will need the name of the Database running on the Oracle server
        
        a single Oracle server can host multiple databases
        
        I need to know which Database I will connect to 
        
        each Database hosts multiple Tables or Views (these hold the data)
        
        So I will need the Table/View name, the data contents (Columns)
        
        it turns out, Oracle has collections of Tables/Views these
        collection are called Schemas, and the default schema is the 
        User Id who built the table/view
        
        ----------------------------------------------
        in this classroom, we will have these Schemas:
        
        world
        customer
        <any you build yourself>
        
        ------------------------------------------------------
        when planning my SQL commands I need to know the Schema (Table/Column/etc)
        
        =====================================================
        
        Planning starts outside the database, it start w/ the business requirments
