5 Conclusion
In manifold application domains arrays form the core underlying structure of
manifold science and engineering data. It is generally accepted today, therefore, that
arrays have to become part of the overall data type orchestration in information
systems. With ASQL we attempt to integrate arrays into the relational model based
on the existing ISO SQL array data type, with the goal of extending applicability of
the relational model to a large class of
related challenges in science and
engineering analytics. An implementation of ASQL has been largely accomplished
and is available for testing.
One practical consequence of this integration is that the historical gap between
data and metadata can be overcome
Big Data
quality of service on data catches up with
metadata capabilities. Additionally, mixing and combining data and metadata
queries has a potential of reducing client/server round-trips and unveils new opti-
mization opportunities.
At the time of this writing, ASQL is being discussed by ISO/IEC JTC1 SC32
WG3 SQL for inclusion in the SQL standard.
