Abstract. Typical University curricula teach computable functions over symbol
chains as the central topic of Theoretical Computer Science. This is motivated
by the idea that the essentials of any kind of computation processes can be ab-
stracted to computable functions. We challenge this idea, motivated by the ob-
servation that modern ICT embedding systems are reactive, communicating,
and non-terminating. Neither do they compute functions, nor do they always
process symbol chains. An obvious example are service-oriented architectures
with their “always on” principle. An adequate, unique theory for such (and
many other) architectures is missing; instead we witness a lot of different ap-
proaches and modeling techniques.
This talk surveys published proposals that attack the above problem. We try to
discriminate fundamental notions and concepts such as refinement and compo-
sition, concurrency, and locality, as they prevail in different modeling tech-
niques for service-oriented and other architectures. Those ideas lead to a fresh
look at some aspects of education, research, and Industrial Applications of ICT.


Keywords. Theory of Informatics, paradigms of informatics, modeling tech-
niques, Service-oriented Computing, associative composition
