Introduction to DBMS:
- Database is simply a collection of data.
- Database management system (DBMS) is a software or application used to store, access data from database (DB).
- Eg. Oracle, MySQL etc.
Disadvantages of traditional File System:
- Multiple file formats (redundancy) and duplication of files in different files (inconsistency).
- Problems to access data such as we need to write new program to carry out each new task.
- Multiple files & formats (Data isolation).
- Security issues in data.
- Problems in transaction of data.
- Hard to manage large amount of data.
- Time consuming.
- Overall cost is high.
So, DBMS offer solution to all those problems that faced in traditional File System.
