摘要

Business intelligence (BI) systems depend on efficient integration of disparate and often heterogeneous data. The integration of data is governed by flows and is driven by a set of information requirements. Designing such flows is in general a complex process, which due to the complexity of business environments is hard to be done manually. In this paper, we deal with the challenge of efficient design and maintenance of flows and propose an incremental approach, namely , for semi-automatically consolidating data-intensive flows satisfying a given set of information requirements.  works at the logical level and consolidates data flows from either high-level information requirements or platform-specific programs. As  integrates a new data flow, it opts for maximal reuse of existing flows and applies a customizable cost model tuned for minimizing the overall cost of a unified solution. We demonstrate the efficiency and effectiveness of our approach through an experimental evaluation using our implemented prototype.
