ANS:

DBMS: It is database management software to store data,retrive, modify the data in the form of tables.

  1. Security: To store the data in DBMS is much secure to store data in a traditional way. Whatever data access whenever it is modifying all records may get in the proper manner.
  2. Easy to store and Fetching the data: Using DBMS software you can save much time to store and fetch data. Only one query can fetch your data from a large table.
  3. Lack Data redundancy : Data redundancy problems may be reduced by DBMS software, you can store your data uniquely.
  4. Data Integrity: Whatever data you are accessing and storing nothing will change automatically, your data will be accurate as you have stored.Example: If in your account has 50$ and you have fetched 20$ so 30$ will remain in your account, not less than or greater than.
  5. No inconsistency: DBMS stored data in a consistent way. Suppose in school management student roll number defines all information of a student, you define roll number as unique key, if school assign, assigned roll number to another student, database will give error and not store this type of entries.

When might it not be best to use a database

Database is mainly required where large data has to be maintained and stored. Database is costly and its maintenance is hard require technical people to manage it

If data is not large and working in a very small organization or business ,coaching then it is best not to use a database.

Example: If you have a small vegetable shop or grocery shop you can maintain your customer account in a copy pen or excel sheet. No need to store customer data in the database.
