Aplicación web para gestionar información logística en una empresa Courier con e-commerce aplicando la metodología scrum

Abstract

Logistics operations in a Courier company with E-Commerce constitute the fundamental basis for the success of its business model, given the growing demand for this service in recent years, it is essential to have a software system that helps manage the information an organized, reliable, transparent and automated manner; this enriches the prestige of the company and positions it against competitors that lack technological tools to improve the management of the services provided. This project is focused on developing a robust and friendly web system using the agile scrum methodology; therefore, it contains the information that details the product backlog based on the user stories collected by the product owner, the general sprint backlog developed by the scrum master, and the description of the activities carried out by the development team in each of the sprints necessary for the construction of the application, from its inception to its implementation and production. For this, the implementation of a client-server architecture is carried out, making use of the PostgreSQL multiplatform technologies for the database, Angular 12 for the presentation layer and .Net 5.0 for the programming of the business logic, the patterns "scoped and transient" to manage the lifetime of instances created by a REST request, therefore all controllers use dependency injection to instantiate the interface of one or more services and to use the methods that the contract declares. Persistence services are managed through the ORM Entity Framework Core, which is responsible for managing the information access layer. The domain layer grants authorization to its methods as long as there is a Json web token in the header of the HTTP requests, these requests arrive in encrypted form with JWT Bearer format to be analyzed by business policies and access to information. The application has mappers for object-to-object conversion, dependency injection to initialize services, elasticity in the implementation of its methods to generate different responses from the server, among other programming practices that help the development of clean, modular, reliable, and code easy to interpret. For the development of the solution, the three-tier architecture is used and all the mentioned technologies are deployed on a server with the CentOS operating system. The Postman tool was used to test the backend, the final prototype was evaluated fulfilling important functionalities of the project using a tool created by the scrum master, this evaluation was carried out with the project put into production and the results of the test through a metric percentage, the evaluation tested the implementation of the hardware and software architecture, the communication between layers and the construction of the project with design patterns; Finally, it was determined that the level of satisfaction with respect to the functionalities of the system is greater than 90%, which indicates that a highly functional product has been built and deployed.
