OO design concept in Software Engineering. In this tutorial, you will learn- In addition, architectural design combines program structure and data structure, thus defining interfaces that will enable data to flow throughout the program. Moving from requirements (what is needed) to design specifications (a description of what should be built) involves a number of steps. The interface design for software is the equivalent to a set of detailed drawings for the doors, windows, and external utilities of a house. and career path that can help you find the school that's right for you.
