Abstract

This thesis deals with the use of component technology for displaying real and historical data in the form of an interactive graph and data points connected by the connectors. The aim of the thesis is to develop software components for graphical projection of historical process data on any operating system. The data for the projection can be obtained e.g. from OPC communication interface or database. The program was developed in Java in NetBeans IDE environment of the 6.91 version. The theoretical part provides a brief description of operating systems, the principles of object-oriented programming, Microsoft COM and AXTIVE X technologies and the ways of communication between the components, then also a brief description of Java and NetBeans developmental environment. The practical part describes the programme structure of the created application. The conclusion of this work gives us the results evaluated in terms of practical use.
