Information Integration is among the most important fields in information management. The problem of integrating data from diverse, possibly heterogeneous data sources is ubiquitious. It arises in companies, scientific repositories, governments, monitoring, data streams, and also personal information management. Currently, the problem of information integration is attacked by a potpourri of dif...

This chapter presents an explicit approach, that is both theory and practice driven, to support evaluation and collaboration activities when creating enterprise architecture. The approach will be applicable in addressing evaluation and collaboration related aspects in two primary phases of the Architecture Development Method (ADM) of The Open Group Architecture Framework (TOGAF). The phases of ...

The Enterprise Architecture (EA) minitrack has been a mainstay of HICSS for the past 15 years. The methodology, tools, and processes of enterprise architecting have evolved during that period. In 2005, Kaisler and Armour identified some critical challenges in modeling, management, and maintenance for EA that needed attention to ensure a viable technical discipline. Over 15 years, we have accept...

This paper is concerned with a real world case study in Business/IT alignment at the strategic level. The case study is situated in the Dutch public sector, involving the Ministry of Social Affairs and Employment (SAE). In this case study, the GEA (Generic Enterprise Architecting) method was used. This paper will therefore take the GEA method as a given. Nevertheless, to better understand and a...

With the advent of potent network technology, software/system engineering has evolved from a traditional platform-centric focus into a network-centric paradigm where the " system of systems " perspective has been the norm. Under this paradigm, architecting has become a critical process in the life cycle of software/system engineering. The need for a structured description of the architecting pr...
