Data quality for data warehousing The need for accurate business intelligence is becoming increasingly critical as decision-making becomes daily more complex and customers demand ever higher levels of service. In this context, the data warehouse offers an ideal storage medium for the corporate data required for decision-making and analysis. The function of the data warehouse is to consolidate and reconcile information from disparate business units and systems to present a consistent picture of the business at a single point in time.  The data warehouse is often at the heart of an organisation's strategic reporting systems, improving ease of access, transparency and delivering the quality of data required for reporting and analysis.

However, often little attention is paid to the data merged into the data warehouse from various operations, which is usually in disparate formats and of questionable quality and integrity.  The business impact of using such unreliable data costs organisations billions in terms of unnecessary administrative costs, not to mention the damage done to the company's brand image.  Even more important, corporate decisions based on such inaccurate data are destined to be flawed.

DQ Global's Match and DedupeExpress de-duplication software links directly to disparate data sources and uses unique phonetic matching capabilities in five languages to identify matches for fast and accurate data cleansing for data warehouse projects.
