Conceptual design involves planning as opposed to visual attractiveness. There is no programming code at this stage, with work being done through sketches, written descriptions, and the like. However, before you can even write or sketch anything, you must understand and analyze your problem. This online tutorials on exploring object-oriented analysis, design, and development helps you do just that.

When you see the words, Object-Oriented, you will usually see another word right…beside them, Object-Oriented Programming, Object-Oriented Design, or…Object-Oriented Analysis.…These are, of course, all connected and refer to the idea that to write any…piece of software we need to do three things.…Understand our problem, plan our solution, and build it, or rather analysis, design, and programming.…They all deal with this larger idea, the larger world of Object-Orientation.…But we have analysis, understanding the problem, what do we need to do?…Design, and here, it's the word design as in plan, not design as in…visually attractive layout.…
This is the conceptual design of the solution.

Let Simon Allardice introduce you to the terms—words like abstraction, inheritance, polymorphism, subclass—and guide you through defining your requirements and identifying use cases for your program. The course also covers creating conceptual models of your program with design patterns, class and sequence diagrams, and unified modeling language (UML) tools, and then shows how to convert the diagrams into code.
