Difficulty: Easy
Correct Answer: Incorrect
Explanation:
Introduction / Context:
In SQL Server, object names are often schema-qualified (schema.object). The default schema for many operations is dbo. Misunderstanding what “dbo” stands for can cause confusion around ownership, permissions, and name resolution.
Given Data / Assumptions:
Concept / Approach:
The identifier “dbo” is an abbreviation for database owner, not database object. Historically, dbo was the owner principal for the database. Today, dbo is also a schema name mapped to that owner context. Qualifying an object with dbo (e.g., dbo.Customers) places it in the dbo schema, which affects default resolution and can avoid ownership-chaining issues. It does not mean “database object.”
Step-by-Step Solution:
Verification / Alternative check:
Query sys.schemas and sys.database_principals to see dbo entries; review documentation on ownership and schemas.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming dbo is merely a prefix; neglecting to set default schema for users; mixing owner and schema concepts.

Incorrect
