1.3 File Systems versus A DBMS

  • Drawbacks of storing the data (500GB) in a collection of operating system files:
    • Do not have such large space of main memory!
    • Even if we do, on a 32-bit addressing computer system, we cannot refer directly to more than about 4GB of data!
    • Concurrency issue!
    • Data restoration if the system crashes
    • Operating systems provide on a password mechanism for security. Not sufficient!
