The main problem analyzed in this work was the need to design and create an internal management system for small and medium enterprices, that would meet their particular requests on usability, extensibility and adaptability at available costs. As solution to this problem was deep analysis of available systems of that kind, and creation of our own system, that had met necessary requirements and even more – had some technological improvements, such as reduced number of users actions, necessary to make things done. This was implemented with the help of AJAX programming technique and a special framework, created for this system. This system can be used to manage projects in a small or medium enterprice, collect statistics about projects, staff work, distribute project tasks to staff and monitor the implementation. There also is an oportunity to generate various reports, such as summary of accomplished tasks for every employee, lists of project tasks and their status and so on. This system can be easily installed in any enterprice because of it‘s client – server architecture, where client connects to the server with the help of a web browser, that can be found in every computer, so there is no need to install system in all computers in enterprice. In that way maintenance costs are reduced, because all you have to look after is server with a system on it.
