Because of being in transition or because of choice, many software development environments make use of both the function-oriented and object-oriented approaches in their software development process. In some cases, object-oriented and function-oriented approaches are used in the development of the same system, such as when using function-oriented analysis with object-oriented design, necessitating a transition or mapping from one model to the other. This paper reviews the issues involved in mapping from a function-oriented software model to an object-oriented software model and presents a strategy for accomplishing the mapping in a consistent and partially automatable manner. The effectiveness of the strategy is assessed with four different applications drawn from the literature. It is concluded that the mapping strategy is feasible and reasonably automatable.

This paper reports the results of a field study of the relationship of information flow to the maintainability of COBOL modules in a data processing environment. The study, which considers 238 modules from three different organizations, examines the correlation of information flow metrics and subjective maintainability ratings. Results of the study show that, for the environments included in the study, information flow does have significant correlation with maintainability, and information flow metrics can be used effectively to help identify modules with low (poor) maintainability.

This paper describes a project presently underway utilizing remotely sensed data and computer assisted procedures for the location and planning of a new state park. Data was collected on an initial study area of 128,620 acres from which several possible park sites were outlined. After a site was selected, similar procedures were used to outline possible locations for various elements within the park. An iterative design procedure will be used to develop an optimum final design for the park. Included is a detailed discussion of the CAGUP (computer assisted land use planning) package developed to support the planning procedure.
