Elicitation of specific requirements of data quality during the Web portal development

Data is one of the most important assets for making decisions and concretizing business in organizations. So, providing data with adequate levels of quality, especially for Internet applications is a very important issue. However, most of developers of these applications do not take in account the incorporation of artifacts to the necessary management of data quality (DQ) from the early stage of development. Due to that, we have elaborated a strategy with two approaches: methodologic and technologic. The first one is aimed to identification the requirements corresponding to the Web portal functionalities for the different kind of users and their specific DQ software requirements. For the technologic approach, an UML profile to model the DQ software requirements is shown; it embraces aspects considered basics to integrate in the specification and modeling of these kinds of requirements. The final objective is developing applications that satisfy the different DQ software requirements specified by each user, at the moment to perform a function with the system.
