DBMS (Database Management System) ek software hota hai jo database ko store, manage aur retrieve karne mein madad karta hai.

 Real Life Example

Sochiye agar college apne students ka data ek register mein likh kar rakhta ho, toh:

• Dhoondhna mushkil

• Update karna tough

• Galti hone ke chances zyada

Ab sochiye agar yahi data computer par ek software (jaise MySQL ya Oracle) mein store ho:

• Fast search

• Easy update

• Safe data storage

 DBMS se fayda hota hai:

• Naya data add karna

• Purana data update/delete karna

• Search karna super fast
