Basis for comparisonTop-down ApproachBottom-up ApproachRedundancyContain redundant information.Redundancy can be eliminated.
What is the difference between top down design and object oriented design?
Whereas object oriented programming languages like C++ and Java programming language follows bottom up approach. Top down approach begins with high level design and ends with low level design or development. Whereas, bottom up approach begins with low level design or development and ends with high level design.

The advantage of top-down design is that much less rework is needed when design changes occur. The parts know how to update themselves based on the way you created them. You can use top-down design techniques on certain features of a part, complete parts, or entire assemblies.
What is system design explain top-down design with an example?
In top-down design, a system’s overview is designed, specifying, yet not detailing any first-level subsystems. Then, every subsystem is refined in greater detail, for example, sometimes dividing into many different levels of subsystem, so that the whole specification is decomposed to basic elements.
