Since in a real environment it is not possible to unify all the information into a single data structure, it is necessary to define a set of global identifiers for each resource object that can uniquely identify this object class to associate the data in different forms. For example, resource object information is typically stored in one form, and associated alarm, performance, work order, and security information is stored in another plurality of forms. When the performance information, the security vulnerability information and the fault maintenance record of a certain resource object need to be known, the global identifier can be used for associating different forms to obtain effective information.
