Design patterns have already gained great importance in both design and implementation of object-oriented software in many diverse areas of applications. In order to get the ideas of design patterns firmly established, they should be taught right from the beginning of a course. This paper outlines how the presently used Objects-First approach can be extended and changed into the Design-Patterns-First approach. The outline of the first five lectures of our university course, which is structured according to this approach, is presented. Some examples of design patterns suitable for the very first lecture of such introductory course are also included.
TOGAF is an Enterprise Architecture framework that provides a method for developing Enterprise Architecture called architecture development method (ADM). The purpose of this paper is whether TOGAF ADM can be used for developing software application architecture. Because the software application architecture is one of the disciplines in application development life cycle, it is important to find out how the enterprise architecture development method can support the application architecture development. Having an open standard that can be used in the application architecture development could help in outsourcing of software development. If ADM could be used for software application architecture development, then we could consider its usability in outsourcing of software development.
The set of tasks solved by computers increases all the time. There are also programming tasks among them. The area, which still resists to automation, is a design of a good architecture. However, most of the current methodologies do not reflect this trend and teach primarily how to write a program in some programming language. The methodology Architecture First turns it up and starts with teaching the architecture. The paper introduces this methodology and explains its basic principles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
