Stock Manager: An Analysis Pattern for Inventories Eduardo B. Fernandez Dept. of Computer Science and Engineering, Florida Atlantic University, Boca Raton, FL 33431 ed@cse.fau.edu Abstract Inventories keep track of what an institution has, such as parts, finished goods, furniture, machinery, etc. A good inventory system is a necessity for any modern business or manufacturing system. We present an analysis pattern for an inventory system that keeps track of quantity and location of items in stock, and updates these quantities according to the different stages of manufacturing or production, from component ordering to product shipping. This is a generic model defined from the abstraction of a real workable inventory and can be extended to fulfill more detailed requirements or similar applications. This pattern is a composite pattern and we identify two atomic patterns as components.
