In System Design, there are two types of approaches followed namely, the Bottom-Up Model and the Top-Down Model. The bottom-up model is one in which the different parts of a system are designed and developed and then all these parts are connected together as a single unit. On the other hand, the top-down model is one in which the whole system is decomposed into smaller sub-components, then each of these parts are designed and developed till the completed system is designed. Read this article to find out more about the bottom-up model and the top-down model of system ... Read More
