In Microsoft SQL Server, what are the valid ways to create and modify tables in a database? Consider both T-SQL statements and graphical administrative tools.

Introduction / Context:
Database schema changes in SQL Server can be performed via T-SQL scripts or through graphical tools. Knowing both methods helps teams standardize deployments and support ad-hoc admin tasks.

Given Data / Assumptions:

• Platform: SQL Server (e.g., 2000 era Enterprise Manager / modern SSMS).
• Task: Create or modify tables.
• Options: T-SQL and GUI.

Concept / Approach:

CREATE TABLE and ALTER TABLE are the canonical ways to define and evolve schema in source-controlled scripts. The GUI (Enterprise Manager / SSMS) issues the same T-SQL under the hood and can be convenient for quick changes and learning.

Step-by-Step Solution:

Verification / Alternative check:

Open a table designer in the GUI and save; the tool shows a generated script. Likewise, running CREATE/ALTER in a query window has the same effect.

Why Other Options Are Wrong:

Option A: Too restrictive—ignores GUI capability. Option B: Too restrictive—ignores T-SQL. Option D: Contradicts fundamental SQL Server behavior.

Common Pitfalls:

Relying solely on GUI without keeping scripts for version control. Making breaking changes in production without reviewing the generated T-SQL.

Final Answer:

Both of the two methods above will work.
