The tiers...
Once the n-tier architecture has been chosen now comes the decision of choosing the indicidual tiers.
To start with lets take the Database tier. Basically this tier is used to store data. In a truly distributed approach data could come from anywhere. Lets leave the decision to a later stage when we have the actual data in hand. Nevertheless just by changing the connection string we should be able to connect to any database for that matter as almost every database answers to SQL queries which are ubiquitous.
Coming to the Presentation tier this will have to be the internet browser the reason being its ubiquity and ease of use.
The Application layer is the tricky part. There are so many technologies to choose from. .Net, J2EE being the top contenders. We shall leave the decision to a later stage.
