Question
Database Schema is the ________ design of the database.
Options:
- Physical
- Logical
- Instance
- Relation
Solution
The correct answer is Logical.
Explanation:
A database schema defines the structure of a database in a formal language. This includes the organization of data into tables, the relationships between those tables, and the rules that govern the data. The logical schema focuses on how data is stored, without considering the physical aspects of how it is actually implemented on hardware.
- Physical Design refers to the actual storage of data on disk drives.
- Logical Design is concerned with how the data structure is perceived and becomes a blueprint for the database.
- Instance relates to a snapshot of the data at a certain point in time.
- Relation typically refers to the tables within a relational database.
Thus, when referring to the schema as the logical design of the database, you're discussing its abstract structure and relationships.
