Abstract:
The paper presents the vision being deployed at the Statistical Office of the European Communities (Eurostat) about a rationalised IT infrastructure for integrated operations of its various statistical production systems. The new architecture being implemented isolates physical data from applications and users, uses database federation mechanisms, strongly relies on the use of meta-data about storage systems, application systems and data life cycles, emphasises the use of thematic and support servers and will use a message-oriented middleware as its backbone for data exchange. Portal technology will provide the unique gateway both for internal and external users to have public or restricted access to information produced by over 130 statistical production systems working in the back-office. Architectural principles and solutions are discussed.
