As of today, most of the data processing systems have to deal with a large amount of data originated from numerous sources. Data sources almost always differ regarding its purpose of existence. Thus model, data processing engine and technology differ intensely. Due to current trend for systems fusion there is a growing demand for data to be present in a common way regardless of its legacy. Many systems have been devised as a response to such integration needs. However, the present data integration systems mostly are dedicated solutions that bring constraints and issues when considered in general. In this paper we will focus on the present solutions for data integration, their flaws originating from their architecture or design concepts and present an abstract and general approach that could be introduced as an response to existing issues. The system integration is considered out of scope for this paper, we will focus particularly on efficient data integration.

The paper presents the application of Java Integration Platform (JIP) to data replication in the distributed medical system. After an introductory part on the medical system's architecture, the focus shifts to a comparison of different approaches that exist with regard to transferring data between the system's components. A description is given of the historical data processing and of the whole area of the JIP application to the medical system.

The article deals with the issue of controlling the autonomous mobile systems. Considered are the problems focusing around the use of controllers with distributed architecture. Contrary to hierarchical architecture, all layers of distributed controller are operating simultaneously, and have an access to both the receptors and to the effectors of the controlled autonomous mobile system. Simultaneous operation of all layers of the distributed architecture controller entails the emergence of the action selection problem. This problem consists in continuous taking decisions: which one of the layers, or which layers of the controller, should have an influence at given moment on the movement of the controlled mobile system. A proposal for a new solution of this problem is discussed. The results of experiments with the use of real mobile robot are presented.

The paper presents major trends in the modern architecture of large database systems. Two types of architecture are described in detail: the parallel architecture and the distributed architecture. It has been widely recognised that centralised, single processor computing systems and centralised database systems in particular are approaching their theoretical limits of performance. Hence we can observe a growing interest among researchers and developers in the design and implementation of highly efficient distributed architecture. The paper focuses on different types of client-server architecture, which nowadays is becoming very popular in data processing systems.
