The trend is Open, Standards-Based 3-tier Architecture for the Web
Notes:
The Internet is driving an entirely new computing model and architecture. It is multi-tier, distributed, and network based. It demands scalable, component technology.
The Intergraph GeoMedia Architecture meshes perfectly with the emerging network computing architecture that maximizes the strengths of host systems (manageability, scalability) and client-server (rich user interface, open choice) while minimizing the weak
One of the major goals of network computing is to lower the total cost of ownership of technology; both on the client side and the server side. Pulling business logic into the network where it can be professionally managed is one facet. Contrast this inte
This multi-tier architecture is commonly drawn as a three-tier environment, but it might easily be even more than three tiers when necessary (for example in widely distributed, component-based solutions).
It is important to note that just as client-server architectures did not completely replace mainframe architectures, network computing will not completely replace mainframe or client-server. Think of it instead as another tool in your toolbox which will f
