      <subfield code="a">This document will present the design and implementation of a software solution developed by the company Innovació i Recerca Industrial i Sostenible SL (IRIS S.L) for a European Project belonging to H2020, Framework Program for Research and Innovation of the European Commission. The author, under the umbrella and supervision of his project partners in the company IRIS S.L, will explain the chosen implementation for the development of the essential components that make up the proposed traceability system. It will present solutions to key / interesting problems in the clearest and most pleasant way possible so that the reader initiated in the programming enjoys it and can find this document useful in their daily life. First, the reader will be put in context with a general vision of the functioning of the system and the role played by each of its components. Secondly, in the body of the document, the architecture and design of all the components will be detailed through explanations and diagrams. Finally, the author will evaluate the work done by the IRIS team after having completed the project and will draw some final conclusions about it.</subfield>
