As organizations move quickly to adopt Service Oriented Architectures (SOA) as a way of responding faster to business needs, data must now be treated as a corporate asset, not just a division or business unit tool. Unfortunately, many data sources are not in the right format or lack the right metadata to allow quick integration to be efficiently repurposed for other uses. By implementing an information management strategy that focuses on data quality and data integration, the benefits of SOA can be further realized. This approach offers great extensibility, allowing applications and users to access information not only within the enterprise, but also across enterprise and industry boundaries. Such complete end-to-end horizontal business and information integration provides new agility and flexibility to support any SOA project.
Data quality is becoming an increasingly hot topic as poor data quality undermines the usefulness of services, lowers user satisfaction and sometimes even breaks the production systems based on an SOA. To improve data quality, automated data analysis, including data profiling and monitoring, are indispensable and important first steps. This hasn't always been the case since many organizations build data sources to satisfy departmental needs. As applications adapt to constantly changing business needs, the structure and semantics of the data they create may change over time. Data format, semantics and rules in one data source are likely different from other data sources. For example, a finance department system may store customer data in COBOL format and represent customers from an accounting point of view, while sales and marketing may store customer data in a database and define customers from a marketing point of view.
