File Organization and Indexing

File Organization and Indexing
The data of a RDB is ultimately stored in disk files
Disk space management:
Should Operating System services be used ?
Should RDBMS manage the disk space by itself ?
2nd option is preferred as RDBMS requires complete control over when a block in main memory buffer is written to the disk
This is important for recovering data when system crash occurs.
