Introduction to database management systems #
Files
- persistent
- on disk
- easy to work with
DBMS
- needs knowledge of software
- needs to design database structure
- can handle more complex situations
Imagine we have 2 different files: student_info and grade_record
Notice the duplication among the 2 files. This will waste storage if using a normal file system. There may also be inconsistencies between the 2 files if only 1 is changed. DBMS can control all of these things for you.
