Uso de GraphQL para mejorar la interoperabilidad entre diversos contextos de datos

Abstract

Abstract: This thesis aims to demonstrate the interoperability of GraphQL as a query language for APIs, through an analysis of its history, architecture, structure, and a comparison with other alternatives used in the software development industry. In the practical part of the project, a web application was created to test interoperability, consuming an API connected to two data sources: a relational database (PostgreSQL) and a non-relational one (MongoDB). To achieve this, an API capable of integrating with these two types of databases was developed. The process was developed using the SCRUM methodology, which facilitated agile development through structured task planning, definition of responsibilities, and role distribution. From a technical perspective, an API was built using the .NET Framework and designed to offer data from various sources through GraphQL from a single endpoint. The user interface was implemented with React, and communication with the API was managed through Apollo Client, a specialized tool that facilitates the handling of queries, mutations, and other GraphQL operations. The result was a fully functional web application capable of efficiently consuming information through GraphQL, validating its potential and usefulness in modern technological contexts.
