Desarrollo de un sistema prototipo para la automatización de los procesos de venta e inventario de un distribuidor de gas licuado de petróleo.

Abstract

The degree work presents the prototype of a system for the automation of the sales and inventory processes of a liquefied petroleum gas distributor, which is made up of a database, a server application, a web application, a client mobile application and a dealer mobile app. The data is stored on an AWS server and on this the server application made on JavaScript was created in conjunction with Nodejs, its function is to provide the REST API web services. These services will be consumed by the three applications that will be developed. To facilitate the administration of the distributor, the web application was created, carrying out activities such as entering user information; manages and assigns orders to delivery people for delivery; In addition, it manages the inventories and reports of the company. On the other hand, the mobile delivery application was created, which is responsible for receiving the requests that the administrator has accepted for subsequent delivery. And finally, the client mobile application was created, which is in charge of requesting the order of gas cylinders. The design of the web application and mobile applications was done through sketches. The sketches were based on user requirements. This document is organized as follows: In chapter 1, all the topics that have been considered essential to have the necessary arguments to carry out the prototype design are exposed. In Chapter 2, the design and implementation of the prototype is shown, in the design the user stories, diagrams and sketches of all the systems were made, in the implementation the coding of the modules can be visualized, providing a better perspective of the programming that was done. Chapter 3 presents the results obtained from the implementation of the different applications, these results are shown graphically. Finally, in chapter 4, the conclusions and recommendations reached throughout the entire project are presented.
