Beside integration of the data in the database, the UPB team works to develop the user interface for displaying the data from the PMUs (by querying the database where the data are stored). This application is based on WireCloud, a component developed under Fiware technology. Even though WireCloud is open-source, plug-and-play widget based and there are many applications already developed, the integration of PMU data has never been done. Thus, in order to create the application, the UPB team had to use the resources made available (already created by other users of Fiware technology and implicitly of the WireCloud application) but to modify them so that the widgets based on which WireCloud works , can query the database and then display the data from the PMU. Once the widget components are created and/or modified, the logic in which each of them interacts must be created.
