Integration platform as central service of data replication in distributed medical system
(2007) Wajs, Wiesław; Rączka, Krzysztof; Stoch, Paweł; Kruczek, Piotr
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.

Propozycja wysokoskalowalnej metody replikacji danych Theta dla rozproszonych systemów transakcyjnych
(Wydawnictwa AGH, 2011) Kasper, Mirosław; Dobrowolski, Grzegorz
The aim of this paper is a proposition of the new replication method for distributed systems with large number of nodes, which is suitable for systems in which demand on high level of scalability is a key issue. The approach is designed for systems working in heterogeneous environments with various platforms, operating systems or database vendors. The article contains presentation of Theta method, description of the communication layer and system components, and presentation of transaction management for the proposed method.

Replikacja w systemach baz danych zaprojektowanych w architekturze wielowarstwowej
(Wydawnictwa AGH, 2008) Kasper, Mirosław
Researches in database replication field, which have been made in recent years, allowed to design and implement many approaches for database replication. The most important features of proposed solutions are improved scalability and system's fault tolerance, and as a result of both of them increased overall performance and availability of the replication systems. Majority of recent approaches for transactional data replication are based on multilayer architectures with middleware tier between client and database tier. In this article there is a presentation of solutions used for realization of middleware-based database replication.
