Question - What are the different levels of abstraction in the DBMS?
Answer -
There are 3 levels of data abstraction in the DBMS.
They include:
- Physical Level: This is the lowest level of the data abstraction which states how the data is stored in the database.
- Logical Level: This is the next level of the data abstraction which states the type of the data and the relationship among the data that is stored in the database.
- View Level: This is the highest level in the data abstraction which shows/states only a part of the database.
