This article presents the modeling of the purchase-sale transaction (pst) in electronic commerce (e-commerce) using different formalisms. E-commerce is an area of interest that is gaining rapid momentum in recent times because of the pandemic. In this work, the pst is a basic scheme that particularly excludes the participation of the intermediary that manages the reception and/or transfer of money. With the above, it is intended to minimize the number of actors involved in the pst to make relevant the contrast of the power representation of different formalisms to facilitate the analysis and make improvements. Firstly, conceptual maps are among formalisms that facilitates the exposition of complex processes. A next formalism is the coverage tree which allows to follow the flow of the pst in a clear way. The pst can be abstracted into a mathematical expression, however, it loses the power of visual scheme. The pseudocode is a way of representing computational processes that, in this case, allows modeling the pst also. Flowcharts are a tool associated with the development of programs that allow visually displaying the events of the pst. |
