摘要
A multi-tier server application architecture provides a simplified programming model of multiple user server applications that enhances programmer productivity. The multi-tier architecture comprises a client tier for client application code that initiates processing by the server application in response to user input, a middle tier of object- oriented server application code, and a database tier of shared access data and management code. A run-time environment for the object-oriented server application code limits access to instantiated objects of the middle tier server application code to a single one of the users. Objects in the middle tier that are instantiated to initiate processing for a particular user and grouped into a collection. The run-time environment manages the flow of execution into the collection such that the collection has only a single logical thread of execution and access by the client application code is exclusive to the particular user.
