A pattern language to deal with Business Resource Management is presented. It covers a great number of applications in business systems, including patterns for resource rental, trading and maintenance, and was designed based on practical experience in information systems development. Existing recurring patterns were applied to form patterns in our language, which were instantiated to this specific domain. The idea has been to make the language as complete as possible in order to be useful for the analysis of a wide variety of applications in this domain. Fifteen patterns are presented together with a diagram showing the precedence for checking the convenience of their utilization. Object models using UML notation are used both to present each pattern structure and a sample instantiation. The pattern language application to practical cases has shown that analysis is easily conducted, as it is a guideline for the work to be done.
