Abstract:
Nowadays, several solutions can be obtained from business intelligence
product vendors for building business intelligence system. However, based on our
experience in implementing business intelligence system in telecommunications,
many practical challenges and problems are emerging continuously when we use the
above products to integrate and mine business intelligence from operational systems
and work flows. As a result of survey, 85% of data warehouse projects failed to
meet their intended objectives. One of the key reasons, we believe, is located at the
design strategy of system architecture whether it is from systematical viewpoint or
not. In this paper, based on our work experience in theory and application, we take
the process of constructing a business intelligence system as a systematic
engineering, and abstracted and advanced a hybrid strategies for constructing
software architecture of telecommunications business intelligence system, which
implements the BI system based on the four types of models step by step, supports
system analysis and design from four levels of analyses, a suite of functionalities
and components for decision support, and a knowledge portal for integration and
presentation of all analysis and design. As an experimental assessment of the above
proposed approach for building hybrid intelligent architecture of Bl system, we
further presented a prototype of the intelligent operational analysis system (IOAS)
for telecommunications operators, which is built on the top of historical
heterogeneous data and real telecommunications environment, and has been shown
to work online user-friendly and flexibly, support decision making systematically.
