139 Modeling Time Using Metapattern

Metapattern is an approach to conceptual modelling. It is technique for meta-information analysis and modelling that emphasizes reusabilty of software. It is a framework that is appropriate to represent the real world domain. It considers context as a fundamental concept. Context is an ordered collection of objects and relationships. An object for information modelling exists in one or more contexts. Another essential principle in information modelling is time. Time helps capturing the dynamic behavior of the real world. It represents changes in states due to an event. Objects in real world exhibit dynamic behavioral features by combination of attributes and values. It is a framework that includes the concepts of context, intext and time. These concepts are suitable to describe a domain under consideration. They are applicable to various application domains. It serves both as the basis for communication and domain understanding. It is in the form of tuple and describes the application domain at meta-level.
