the FAMHP manage the document file of medicinal product, like authorization document, leaflet… with an external application. The tool becoming obsolete and that’s why the FAMHP would like to integrate the management of document with the Extrar application (management of medicinal product). The idea is to unified the process in a new application. The busines take the opportunity to review their business process and so create a new application which be able to manage in better way the authorization flow of a medicinal product. For this application we introduce the microservice service architecture.
