Please let me know if Microsoft three-tier Data Access Pages are built on the traditional model for web applications where a user opens up a web page and have to wait on the serer to supply its data.  
                        OR
Because I am using Microsoft’s that are a collection of Component Object Model (COM) controls for viewing published spreadsheets, charts, and databases on the web.  The browser loads the Office Web Component engine.  This engine is responsible for both rendering the interface the user sees and communicating with the server on the user’s behalf. The engine allows the user’s interaction with the application to happen asynchronously — independent of communication with the server. So the user is never staring at a blank browser window and an hourglass icon, waiting around for the server to do something.

Tell me what you think?

I'm not aware of a three-tier model within Access. At best, you'd have two-tier - the server, assuming you're storing data on a SQl Server or something similar, and the workstation. Three tier would indicate a machine sitting between the two which would process business logic, handle database reads/writes etc, and Access doesn't do that.

If you're asking which approach is better, then the answer is "it depends on what you're looking to achieve". The second example would probably be more interactive, while the first would be a more traditional (but less risky in terms of data loss).
