This paper presents a conceptual toolbox for software specification and design that contains techniques from structured and object-oriented specification and design methods. The toolbox is called TRADE (Toolkit for Requirements and Design Engineering). The TRADE tools are used in teaching informatics students structured and object-oriented specification and design techniques, but the toolkit may be of use to practicing software engineers as well. The conceptual framework of TRADE distinguishes external system interactions from internal components. External interactions in turns are divided into external functions, behavior and communication. The paper shows that structured and OO analysis offer a small number of specification techniques for these aspects, most of which can be combined in a coherent software design specification. It is also shown that the essential difference between structured and object-oriented software design approaches lies in the separation of data storage, data processing and control in data flow diagrams, versus the encapsulation of these into objects by OO analysis. Functional and subject-domain-oriented decomposition, on the other hand, are shown to be compatible with both approaches.
