Employee self service

An Employee Self Service System (ESSS) has been designed and implemented using Microsoft Visual C++ and Microsoft Distributed Component Object Model (DCOM). The ESSS is a real time, three-tier (presentation, application, and data), distributed application capable of running on a configurable number of personal computers. It allows users to view, change, and update their employment-related information, such as personal information, benefit selections, and retirement contributions. To support data efficiency, the database is fully controlled by the data-tier. To support network efficiency, data storage is provided by the application-tier for the frequently requested data. To support user efficiency, the users are provided with a single-window user interface that covers all the functions needed to perform a user task. An in-depth description of DCOM technology is also provided with this report
