Specialty needed: Information System, Computer Science. I'm in the process of preparing a proposal for a search study and I need assistant in "related studies" section e.g. collecting similar and related previous studies. Summary of the search study: An object-oriented information system is decomposed into subjects (Subsystems); each subject is decomposed into classes of objects. There are several types of links between the system classes. These links affect the 0-0 system characteristics which in turn affect its quality. The study will attempt to assess the interdependency weight for these links which are: There are several types of interactions between system classes, they fall into two categories physical and conceptual connections. The physical connections (links) are: Whole Part Structure, Inheritance, Instance Connection, and Message Connection. There is a conceptual link between two classes if they share some property. For example if two classes are instantiated in the same slice time, they are linked by a conceptual time link. These links differ from one another depending on their strength, taking into account that physical connections are stronger than the conceptual ones. Required: Metrics used for measuring quality of object-oriented system architecture design (system level). Studies that tried to calculate the weight for these links at high-level. Studies that tried to calculate the weight for these links at low-level. Any related study. The study is at system level (architecture level) NOT at low-level (programming) because it's not the study scope.
