In-Depth Information
business intelligent purposes. Having a unified
view to the enterprise data can be very beneficial
for the enterprise, and virtually all large enterprises
are using this technique (Watson, Goodhue, &
Wixom, 2002). For reporting needs, it is sufficient
to have read-only access to the master data, making
it possible to use a replica of the data instead of
providing full master data functionalities (Walker).
Messaging can also be used to implement
private processes within an enterprise (Bussler,
2001; Sadiq et al., 2005). Services and web service
technology can also be used to provide access to
the existing messaging infrastructure by replacing
the messaging adapters with web service wrap-
pers (Harikumar, Lee, Hae Sool, Haeng-Kon, &
Byeongdo, 2005).
Messaging Based Approach
and Business-to-Business
Communication
QSE ANALYSIS
QSE is based on two principles. Firstly, it uses
procedures from qualitative research to concep-
tualize and to categorize the service candidates.
Secondly, it uses known characteristics of reusable
services and the Zachman Framework (1987) as
core categories for the analysis.
The grounded theory was originally introduced
by Glaser and Strauss in 1967 and is now widely
used in qualitative research (Robson, 2002; Strauss
& Corbin, 1998). Grounded theory has been pro-
posed to be used in the requirement engineering
practice in earlier studies (Galal & Paul, 1999).
The use of predefined core categories is against the
principles of the original grounded theory, but is
necessary to reuse the knowledge of known char-
acteristics of enterprises and services. Therefore,
QSE relies on the assumption that the enterprise
fits into the Zachman Framework (1987) and that
the reusable services in the enterprise have similar
characteristics as identified in earlier research.
The QSE analysis consists of three phases:
The message-driven approach to SOA focuses
on the messages being transmitted between the
systems (Arsanjani, 2005). This approach is well
supported by many current BPM platforms, as
they rely on messaging technologies to facilitate
interactions between organizations running poten-
tially heterogeneous systems (Sadiq, Orlowska,
& Sadiq, 2005).
The message-based approach is popular in
Business-to-Business (B2B) communication,
where several standardization organizations are
developing domain specific message standards.
B2B communication consists of public and private
processes and the connections between these two.
Public processes can utilize B2B standards, which
consist not only of the message format, but also of
the process of how these messages can be used in
inter-enterprise communication. (Bussler, 2001)
True B2B collaboration requires more so-
phisticated logic than a simple request-response
approach provided by web services, and B2B
communication is often based on a business agree-
ment between the parties. Models for B2B com-
munication typically require specified sequences
of peer-to-peer message exchanges between the
parties following stateful and long lasting busi-
ness protocol used to orchestrate the underlying
business process. These protocols define the
messages as well as the behavior of the parties
without revealing their internal implementation.
