Desarrollo de un sistema distribuido de gestión de fotografías: subsistema de consulta.

Abstract

This Curricular Integration Work is focused on the development of a query subsystem implemented through ASP.NET web API technology that allows sending previously stored photos from tags defined by a user. The subsystem processes the tags entered by a user through a photos acquisition subsystem. It consumes information from a storage subsystem to later return the filtered information based on the request made by the user, which includes the labels chosen by the user, for which it consumes the photos obtained through the classification subsystem. As part of this work, to emulate the functionality of the storage, classification and photos acquisition subsystems, stubs will be used. The query subsystem corresponds to the back-end that the system requires for its operation, however, to be able to test the subsystem it is required to emulate the front-end. Since in this work the photos acquisition subsystem is not developed, a stub must be created for it, and therefore, to emulate the front-end a web application will be developed using the Angular framework. For the development of the back-end, the ASP.NET web API framework will be used, which allows a web service implementation where the necessary endpoints are located to process the requests and responses that arrive from the front-end. In addition, the storage subsystem stub, the classification subsystem stub, and the query subsystem logic will be implemented in the back-end. For the development of the storage subsystem stub, the Entity Framework will be used, which allows the interaction of a database with the back-end. For the development of the classification subsystem stub, a set of initial directories and photos will be implemented and integrated. For the development of the query subsystem, a stub will be implemented that emulates the photos query logic.
