Core Mindsets for SQL Server Professionals

1. Data is a Priceless Asset

Always prioritize the integrity, accuracy, and security of data. Every operation must be carefully considered to protect this most critical asset.

2. Think in Sets

SQL is a declarative language that operates on sets of data, not row-by-row. Learn to think about operations on entire datasets.

3. Performance is King

An inefficient query can slow down the entire system. Always think about indexes, execution plans, and how to optimize for speed.

4. Structure is the Foundation

A good database design (normalization) will prevent countless future problems. Spending time on careful design is a worthy investment.
