Which of the following levels is considered as the level closed to the end-users?a.External Levelb.Internal Levelc.Conceptual Leveld.Physical Level

To determine which level is closest to the end-users among the given options, we should analyze what each level represents in the context of database systems:

1. External Level: This is the level that is closest to the end-users. It represents how users view the data, including the various user views, such as forms and reports. Each user can have a customized view of the data according to their requirements.

2. Internal Level: This level describes how data is physically stored and accessed in the database. It deals with the data structure and is not typically visible to end-users.

3. Conceptual Level: This level represents the logical structure of the entire database. It outlines what data is stored in the database and the relationships among the data. While it’s more user-friendly than the internal level, it is still more abstract than the external level.

4. Physical Level: This refers to how the data is physically stored in the database, including file structures and indices. Like the internal level, it is far removed from end-users.

Final Answer

The level considered closest to the end-users is a. External Level.
