SQL Server Solutions - Beware Views Within Views Within Views
Views provide an abstraction layer that can simplify queries and make code more manageable. But if you aren't careful, too many nested views can negatively impact query performance. Views include overhead such as columns and joins that aren't needed for your specific query. This problem gets worse with nested views. Of course, when readability and ease of reuse are paramount, using views - even views within views - is perfectly fine. But when every second of performance is critical, consider tweaking your queries for more specialized usage, even at the cost of reusability.
