Extraction-Transformation-Loading (ETL) and Data Cleaning tools are pieces of software responsible for the extraction of data from several sources, their cleaning, customization and insertion into a data warehouse. To deal with the complexity and efficiency of the transformation and cleaning tasks we have developed a tool, namely ARKTOS, capable of modeling and executing practical scenarios, by providing explicit primitives for the capturing of common tasks. ARKTOS provides three ways to describe such a scenario, including a graphical point-and-click front end and two declarative languages: XADL (an XML variant), which is more verbose and easy to read and SADL (an SQL-like language) which has a quite compact syntax and is, thus, easier for authoring.
