the most basic yet challenging problem of business integration is reconciling differences between data and messages within the enterprise. enterprises have multiple application systems that hold data related to the data in other applications. the problem is the way in which those data are expressed - the semantic (or meaning) and syntactic (or format) incompatibilities between the disparate data models and representations used by applications. in a way, the data model for all of these different bits and pieces is inconsistent.
the crucial role of transformation in a business integration strategy is to be able to map these inconsistent data formats and data models into common objects that can be shared among the various applications. the role of data transformation is crucial, because at each and every step of a business process, transformation of the data is typically required.
the ability to transform complex data is of particular importance today because the rush to operational efficiency and regulatory compliance pressures has created the need for a new class of high-performance, mission-critical applications. these applications require accurate real-time data transformation between unstructured and semistructured document and message formats, such as nonstandard variants of edi, legacy cobol structures, xml, and proprietary business document types such as microsoft office and adobe pdf.
data transformation is often a major barrier to achieving business value and roi from business integration projects, due to the diversity of formats used in the modern enterprise. until now, data transformation has been accomplished with tools and technology that: fail to address diverse data types and often require costly custom development exacerbate technology proliferation issues drive up overall integration costs, complexity, and project timelines classes of transformation problems
from a business viewpoint, the most pressing problems associated with data transformation are: the need to channel a large and diverse amount of information to end users and systems in support of custom... 下一页
