INTRODUCTIONThe evolution of E commerce has revolutionised way of doing business and shopping. Ithas transformed overall process starting from data gathering to its processing. Moreover, aproper system is been designed to provide ease in shopping (Garvey, Book & Covert, 2016.). Itis very necessary for companies to identify functional and non functional requirements fordesigning. It describes how and which users will interact with system, how data will flow,process, etc. On basis of it, entire system is developed and installed. Also, it enables in providinga framework through which entire system can be designed. For this there are many onlineplatforms available on which system designing is done. This assignment will show contextdiagram of an online shopping system. Also, what are the functional and non functionalrequirements of system. At last practices of improving system will be discussed.Draw a context diagram for the systemA context diagram represents the overall design of a system. It demonstrates differentparts, entities, boundary, etc. of a system which makes it easy to understand external and internalfactors that will interact with system (Benveniste & et.al., 2018). It is a very high level diagramthat is built with blocks. There are two types of context diagram which is described below :-Entities –In this only entity is shown that represents users which interact with system.Relationship –It describes relationship between entities and system.1
Figure1Context diagramThis diagram represents overall structure and process of how each entity like customers,order, administrator, etc. these all are connected to online shopping system and the input andoutput of data and information is different.Draw data flow diagram level 0 for the systemA data flow diagram shows how data flows within system. It also provides informationabout input and output of each entity and process as well. The DFD differs on levels of its entityand process. It can be 0, 1,2, etc. (Hoppe & Hisschemöller, 2018).Through DFD improvementscan be done in system by making changes in flow of data. This is done by identifyingdeficiencies in process (Data flow diagrams, 2018). There are two types of data flow diagrams.Physical –It demonstrates how things happen in data flow by specifying things such as files,people, etc. involved in it.Logical –It shows what happens in flow of data, which user are receiving information, wheredata is been transmitted, etc.2
