The system is a layer of communication and performs routing of data through synchronous and asynchronous messages between PSZ systems, as well as external systems.

The project include: the central module (SB) responsible for the authentication and authorization of system nodes and message processing, proxy modules dedicated to system Broker SI PES customers, which are responsible for receiving and processing messages (SBpx), Central Database Users and Nodes (CBUiW), whose mission is to collect and share information about all users of PSZ systems with the module CAS (Central Authentication Service) which is responsible for implementing the functionality of SSO (Single Sign-on).

The project is realized in SOA architecture. During the project we use both commercial solutions (including Software AG webMethods integration platform) and open source solutions (eg database PostgreSQL, EnterpriseDB and Red Hat products).
