Consequences of trading hours deregulation. A spatio-temporal object-oriented data model for Madrid region

During the summer of 2012 the Commercial Revitalization Act (Ley de Dinamización Comercial) was passed in Madrid region. It allows businesses to open 24 hours a day 365 days a year and start the business activity without a license. In this paper we present the design of a object-oriented data model to study the impact of this measure on the trade according to size and location of the establishment. The database is not only spatial but time is included in the design as a main piece to determine the effects faithfully. The results show a limited extension of time for most establishments and areas as well as a small demand transfer small to larger ones that also occur in a lower degree without the application of this measure.
