The level of data abstraction that describes exactly how the data is actually stored is called the Physical Level (also known as the Internal Level). This is the lowest level of data abstraction and it details the complex low- level data structures and the physical storage of the data on hardware like disks or memory. It includes how the data is organized, stored, and accessed physically
Summary of Data Abstraction Levels:
- Physical Level : Describes how data is stored physically in the database system (data files, indexes, storage blocks, etc.).
- Logical Level : Describes what data is stored and the relationships among the data, abstracting away physical details.
- View Level : The highest level, showing only relevant parts of the database to users, hiding complexity.
Therefore, the answer to the query is the Physical Level of data abstraction
