SOA in PA

Next reference to hype cycle. SOA - service oriented architecture is like internal web services tool for building open and effective teleinformatic environment. It is way for assuring technical interoperability in public administration. Based on open standards, ICT systems may effectively communicate each other without necessity for previous cost-consuming process of mutual adjustments of various applications used by PA. Technical interoperability gained through SOA makes also available creation of information model of PA where data will be coherent and based on reference sources. Another advantage of building SOA by PA is that public administration became more independent from applications providers.
