1. A construction method for a hazardous chemical management database, comprising following steps:
determining a plurality of entities involved in a plurality of fields that are involved in a plurality of stages throughout entire lifecycle of hazardous chemicals, and classifying the plurality of entities to define a plurality of entity classes involved in the management database;
respectively determining a plurality of entity classes involved in each stage of the hazardous chemicals throughout its entire lifecycle, and determining one or more relationships between every two of the entity classes involved in the same stage;
respectively defining corresponding relationship class according to each of the relationships;
using the relationship from one or more of the relationship classes to constrain the relationships between every two entities, so as to construct an ontology of the database; and
importing actual data of the hazardous chemicals throughout their entire lifecycle into the ontology, so as to carry out instantiating of the ontology,
wherein the entire lifecycle of the hazardous chemicals comprises six stages including “production”, “storage”, “transportation”, “trade”, “use”, and “disposal”, and the management database comprises five entity classes including “personnel”, “abstract object”, “activity”, “organization”, and “resource”, and
wherein using the relationship from one or more of the relationship classes to constrain the relationships between every two entities, so as to construct an ontology of the database includes:
using the relationship from one or more of the relationship classes to connect every two entities, and using a Domain description and a Range description provided by a Resource Description Framework Schema (RDFS) in an ontology development tool named protégé, to constrain a definition domain and a value range between the two entities, so as to construct the ontology of the database.
