Table Space: The table space is useful for storing the data in the database. When a database is created two table spaces are created.

a) System Table space: This data file stores all the tables related to the system and DBA tables
b) User Table space: This data file stores all the user related tables

We should have separate table spaces for storing the tables and indexes so that the access is fast.

 Data Files:  Every Oracle Data Base has one or more physical data files.  They store the data for the    database.  Every data file is associated with only one database.  Once the data file is created the size cannot change.  To increase the size of the database to store more data we have to add data file. 

 Parameter Files:  Parameter file is needed to start an instance.  A parameter file contains the list of instance configuration parameters 
 E.g.  Db_block_buffers = 500  Byname = ORA7  db_domain = u.s.acme lang

Control Files:  Control files record the physical structure of the data files and redo log files, They contain the Db name, name and location of dbs, data files, redo log files and time stamp.
