A confederation of patterns that covers a great number of applications in business systems is proposed. Resource Management is the term used to d efine these a pplications. It i ncludes patterns for Resource Location, Resource Trading and Resource Maintenance. They are applied to examples as medical attendance, video rental, real estate rental, library service, show box office, fertilizer retail store and car repair shop. The proposal is based on professional practice, and results from the combination of recurring patterns, already covered in other PLoPs. The practice used mostly procedural languages, but through object oriented reverse engineering of real systems it was possible to explicit the proposed object oriented patterns.
