FIELD OF THE INVENTION
The present invention generally relates to the field of computer systems for developing business applications; and, in particular, it relates to a method for controlling and tracking client access to server software being executed by the computer system.
BACKGROUND OF THE INVENTION
In the field of client/server computing systems, some server software may not be multi-threaded. In such cases the server software does not allow another process to make multiple simultaneous calls to it. This is a limitation of single-threaded client/server software. Hence, remote clients need their own connection into the server software, with either a disproportionate amount of the work being done on the client, or wasteful duplication of processes being executed on the server.
The problem is compounded when the server software is session-oriented, that is, the work currently being performed depends upon the history of the previous work done. This requires not only that the server software service all the clients simultaneously, but it must also know exactly what has been done by each client.
A more difficult problem is that clients are continuously making requests to the server and each request is disjoint from that server's point of view.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide access to a server through a unique process that provides a component instantiated for each active client in its own process space, thereby circumventing the multi-threading restriction of the server software.
Another object of the present invention is to provide a method in a server process for storing a persistent collection of data pairs to overcome the problem of disjointed requests on the server by the clients.
Still other objects, features and advantages of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein is shown and described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated of carrying out the invention. As will be realized, the invention is capable of other and different embodiments, and its several details are capable of modifications in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive, and what is intended to be protected by Letters Patent is set forth in the appended claims. The present invention will become apparent when taken in conjunction with the following description and attached drawings, wherein like characters indicate like parts, and which drawings form a part of this application.
