2SYSTEMS DESIGNAnswer to question 1Top-down and bottom-up are the two approaches to software development or theobject-oriented programming.The top-down approach software development approachThe top-down approach basically breaks down of the system into multiple sub-systems and this approach leads to reverse engineering of the system. Each and everysubsystem is taken into consideration and is treated as an individual system (Haken, 2013).Again those sub-systems are dispersed or better say decomposed. This procedure keeps oncontinuing until the lowest level of the aforesaid top-down approach hierarchy is reached.The top-down approach initiates with a general model and it illustrates the subsystemscoming along with it on progress. When all the associated sub-systems are finishedexecuting, the whole system’s design can come to the existence (Zhang et al., 2014). The top-down approach is applicable for the software where the software developers are planned to bedesigned from scratch or from the start and the details of the websites are not known.The bottom-up approach software development approachThe bottom-up approach involves composing of the more complicated system byutilizing and accumulating various subsystems. Thus it is an emerging system. Bottom-upprocessing is one type of processing which deals with the data processing and this dataprocessing is based completely on the incoming data. The components at the higher level getcreated and the process goes on until the components get merged to a single component (Li etal., 2013). The quantity of abstraction goes on increasing with the level it goes higher. Thisapproach is applicable in the case where the software developers are willing to build software
