Abstract
Data quality concerns arise when one wants to correct anomalies in a single data source, or when one wants to integrate data coming from multiple sources into a single new data source. The main quality problem that arises is that the same real object is modeled by different data records. This is called the Object Identity Problem and may result from several factors. Correcting the Object Identity Problem is ensured by a set of software solutions called data cleaning tools. A new tool, called AJAX, is proposed whose main goal is to facilitate the specification and execution of data cleaning programs either for a single source or for integrating multiple data sources.
