Three Tiered Architecture:

Our medical ASP is organized under a three-tier architecture which enables rapid design and development of the system. Separating the functions into distinct tiers makes it easier to monitor and optimize the performance of each layer. Load balancing and adding more capacity can take place independently at each layer. Multi-tier architecture also makes it simpler to scale the system across multiple processors on different machines.

The three tiers reflect the specialized functions of a web-based enterprise application.

1. The presentation layer delivers the application to the end users on the Web.
2. The business logic layer contains and executes the rules that run the application.
3. The database layer manages the data required by the application.
