ENVIRONMENTAL LOAD ASSESSING DEVICE HAVING AN OBJECT-ORIENTED DATABASE WHICH STORES, AS OBJECTS, PARTS OF AT LEAST ONE PRODUCT AND/OR PROCESSES IN A LIFE CYCLE OF THE SAME

An environmental load assessing device includes an object data storage section composed of an object-oriented database. The object data storage section stores data inputted from an input section. Specifically, parts of a product to be assessed and/or processes in a life cycle of the product are stored as objects, respectively. Attribute data of the parts and/or the processes are stored as attribute data of objects corresponding to those parts and/or processes. Coupling relationships between the parts and/or between the processes are defined by classes and attribute data of objects corresponding to those parts and/or processes and stored.
