This article presents the characteristics, advantages and disadvantages of using the Spring framework in the programming of web information systems, in order to highlight its importance in programming. As well as the comparison of working on the same projects, in this case points of sale, but with different tools and frameworks, which in development or programming make the difference in terms of management, distribution, information control and development time, which that allows us to evaluate the performance and response time that a system can have before the requests that a user can generate when requesting data queries. As Spring is a framework that supports the development of business applications in Java, it emerges as an alternative to the complex J2EE platform, providing important features such as dependency injection, transaction management, support for automated tests and support for oriented to programming aspects, so it is a tool that every programmer should know.

The introduction of 4.0 technologies in universities requires profound changes, where technologies must be used as cognitive tools that develop students' knowledge, their critical thinking and their ability to communicate with others. The objective of the present work is to show the design of a web system focused on registering users, test programming registration with reagents that support the subject of web programming fundamentals aimed at education 4.0, which is distinguished as virtual courses that include a interactive presence in the form of blended learning and features driven by major challenges in educational technology that could include any of the following: personalized learning process, gaming and virtual reality/augmented reality based learning, communities of practice, adaptive technologies, data analysis learning, intelligent Chabot and electronic evaluation.

The objective of the present work is to apply fuzzy logic in an algorithm that supports decision-making for the selection of reagents (questions) focused on education 4.0, for which the Delphi method is used to identify the process that must be followed when selecting the questions, that must be presented to students when they use a content reinforcement tool or system that is focused on evaluating student knowledge. The area of Artificial Intelligence IA has several areas of knowledge that could be applied in this algorithm, however, due to the fact that the ways of learning of the students are not known, the fuzzy logic technique is chosen since the sets They can present fuzzy data or with a membership function that varies according to the learning style of the learner.

Augmented Reality (AR) is a technology that allows users to have interactive experiences between themselves, the physical world, and the virtual world through the use of digital devices that have a digital camera, such as smartphones, tablets, desktop computers, or laptops. AR has various applications such as entertainment, advertising and marketing, medicine, architecture, engineering, tourism, e-commerce, or education; in the latter, students can visualize different concepts of programming fundamentals or object-oriented programming. The objective of this project is to create a mobile application applying augmented reality to the fundamental concepts of programming so that students can improve their understanding and retention of syntax and examples of terms used in Java. The application is focused on control structures, conditionals, classes, methods, constructors, objects, and arrays. Searching for concepts on the internet, physical or electronic books, or even with classmates, can take up to 5 minutes, with this application, it is possible to see the structure and/or examples in a matter of seconds, besides having the advantage that it does not require internet connectivity.

This article presents the development and application of a web system that allows the registration of data from small businesses, in order to publicize their products and services, as well as their opening hours, type of payment received, location, social networks and telephone. There are three types of users: the administrator, the business owner, and the customer. The SCRUM methodology is applied for its development. Only the Execution and Adaptation phases will be presented in this article. In addition, its improvements and application in businesses in the San Martín Texmelucan región are visualized, an MVC architecture (Model-View-Controller) and free development technologies were used.
