Development of Lan Chat Messenger (lcm) Using Rational Unified Process (rup) Methodology with Object Oriented Programming

This paper established how LAN Chat Messenger (LCM) using Rational Unified Process (RUP) methodology provides low-cost communication between staff in an organization. In the process, it enables users to make voice calls, chat and transfer of small to medium-sized files. The paper provides information about how voice calls are made, call history is shown, chat conversations are saved and quick file transfers are made through LCM which minimizes the communication issues, which are mainly time and cost of communication and maintenance. Object oriented programming was used to develop the LCM system and the programming language utilized was JAVA, focused on the implementation of two-tier architecture within TCP/IP. The system was implemented based on a standalone application using pure object oriented language. This system was successfully tested at one of the organizations for the domain study.
