TRITON - An event driven SOA architecture MSIS Jakob Engdahl, Statistic Sweden

Background Process orientation Expensive data collection and data editing process Problem with a lot of old stovepipe systems A vision for a service oriented architecture

Requirements on architecture Supports each process and activity with data and metadata Has a service oriented form Is metadata driven Meets quality requirements such as stability, security etc Gives the subject matters the possibility of choosing relevant services and functions Lessens the dependence between the process services Helps create a overview of the progress of the process Does not require unique adapters between each subject matter and function

Each process needs input in form of data and or metadata to execute Each process results in data and/or metadata after execution Input and output Data Metadata Data Metadata

Deciding Architecture Four forms of architecture was discussed – Traditional SOA with Business object focus – Traditional SOA with Business process focus – Event driven SOA with Choreography – Event driven SOA with Orchestration Each architecture form was analyzed based on the requirements

Traditional SOA – Business object focus Manual investigation Check data Web collection tool Questionnaire Rules for data checks Sample objects Micro data Permission

Collaboration More difficult to collaborate with the logic ”in between” the functions Collaboration possible when creating IT-tools for specific processes

More information than micro data is needed to execute an activity Information model is not dependent on architecture or technology ”Generic Statistical Business Information Model” Information Architecture
