Desarrollo de un sistema de gestión de aprendizaje en línea (lms) con herramientas open source

Abstract

In recent years the consumption of web software for online learning has increased, this as a result of technological development and the growing labor market, where greater preparation is increasingly required in its workers, making people who want to get a job look for ways to improve their preparation, one of these being the consumption of LMS web pages. Given that today there are technology and tools that facilitate the development of learning software, this project will develop an online learning management system, LMS with open-source tools for the management of educational content of the online platform. For the development of the web application, a search was carried out in similar applications and projects, this with the aim of obtaining the basic functionalities, tools and methodologies that software development would require. The agile methodology Extreme Programming XP was one of the most used for this type of projects, given its flexibility to make changes, for being optimal for the realization of small and medium projects and for using good practices that focus on planning, design, coding and testing. In addition, in the planning and management of the project, user stories are used, which help to establish the schedule of the software, and facilitate the realization of the layout. In the development of the web application, it was important to select the appropriate tools, that is why when taking into account the design that should be implemented in the project, added to the client-server architecture on which it was based, the Angular framework was chosen in the client layer.js, this to achieve a single-page application, which can be reloaded dynamically and thus achieve fluidity when displaying its content, in addition the Bootstrap and PrimeNG frameworks were used for the design of interfaces, as a result it was possible to develop clean and responsive pages with the use of the different tools they offer, in the server layer a Node environment was available.js with the Javascript language for the execution of the backend, in addition to the use of the Express framework.js an API was achieved, which through an HTTP protocol receives requests from the frontend and sends as a response information hosted in the databases, in addition, websockets were used for continuous communication between the server and client, which allows certain requests to be made efficiently, an extra module was also available at the server layer, where payment gateways were used that used services such as PayPal and PayPhone for making payments, finally, in the database layer a relational data management system called PostgreSQL was used through the ORM sequelize for information in general, Vimeo for hosting the videos used in the web app and Google Drive for hosting the files used. At the time of starting the development of the web project was investigated in different LMS pages and instructors, the basic requirements that the web application should have, this caused the extreme XP Programming methodology to be used, which raised the functionalities of the application as user stories, this helped in the development and design of the project, since it facilitated the fulfillment of the requirements that were expected of a page designated as LMS.
