logical data is the ORACLE view of the storage.
physical data is the OS view of the storage.
now you wanna make a new database :
1- prepare your OS to receive the final data: create data files : Physical storage.
2- prepare Oracle to receive your data: create tablespace, now these tablespace should be defined to the os, this gonna be made by choosing the previous datafiles.
3- at this step you can fully forget/ignore the OS ! you'll be dealing with the table spaces (the logical view/Oracle view), ie, you can now create Oracle objects (tables, indexes and stuff) and toss them on the .... tablespaces !!!
nice isn't ?
