It is a common mistake to code business logic by exclusively using script in ASP pages. ASP is interpreted at run time, so pure script implementations are much slower than those that use precompiled objects. Also, because the business logic is exposed as script, it can be viewed by anyone with access to the server, making it vulnerable to tampering. Lastly, scripted business logic is not easily and cleanly reusable. As the application grows, so does its complexity. Objects become enmeshed with other objects, the system becomes hard to manage, and the bugs multiply.
For all these reasons, ASP should only be used as the “glue” that holds components together. If you’re serious about scalability, you must implement your business logic as components.
