SQL Server provides several programmability objects that help you encapsulate logic, improve code reusability, and enforce business rules within your database. These objects—views, stored procedures, functions, and triggers—each serve distinct purposes and offer unique capabilities for database development.

Scenario

You're a database developer at a growing e-commerce company. Your team manages a SQL Server database that handles customer orders, inventory, and reporting. As the application grows more complex, you notice:

  • Developers write the same JOIN queries repeatedly across different applications
  • Business logic is scattered throughout application code, making it hard to maintain
  • Some data modifications need automatic validation and logging
  • Complex calculations appear in multiple queries, leading to inconsistencies

You decide to create specific SQL Server objects to centralize logic, improve maintainability, and enhance security across your database applications.

What you'll learn

In this module, you'll explore the core programmability objects in SQL Server:

  • Views - Virtual tables that simplify data access and provide security boundaries
  • Stored procedures - Precompiled T-SQL code blocks for complex operations and data modifications
  • Scalar functions - Reusable calculations that return single values
  • Table-valued functions - Functions that return result sets for use in queries
  • Triggers - Automatic responses to data modifications or database events

You'll also learn decision criteria for choosing the right programmability object based on your specific requirements.
