CARO, Angélica; FUENTES, Alejandra  e  SOTO, M. Antonieta. Developing information systems focused on data quality. Ingeniare. Rev. chil. ing. [online]. 2013, vol.21, n.1, pp.54-69. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052013000100006.

Information systems can be compared with the manufacturing systems in the sense that the latter produce physical products from raw materials and the first generate information products from raw data. This analogy emphasizes the idea that products, whether physical or information, have a value that is transferable to the consumer. If we see an Information System as a system whose purpose is to deliver products of high quality information, then the Data Quality or Information Quality is an important factor to consider in its production. Indeed, the data quality is often defined as "data suitable for use", i.e., data that are useful for consumers/users in a specified context of use. Considering the above, this research focuses on the idea that the quality of data must be addressed from the beginning of the development of an information product, i.e., from when creating the information system that will generate. Thus, this paper presents a method that leads to a development team to build information systems focusing on data quality. Specifically, the first version of this method, aimed at the requirements specification stage of an Information System with Data Quality. A case study showing how the method has been applied in the development of an information system is presented.

Palavras-chave : Data quality; information quality; information product; software development; method.
