This document presents the components encompassing the communication layer, graphical interface, and security measures for BIGG. BIGG goes beyond theory by adopting a business case-oriented approach. To meet the diverse needs of various data-based verticals and specialized business scenarios, end-user applications—both graphical and non-graphical—are developed as practical solutions. These applications empower users to harness innovative data-based services, whether by integration into existing systems, the creation of new interfaces, or the development of mobile applications and monitoring tools. This document provides a comprehensive overview of the BIGG framework, its key Communication layer, Graphical interface and Security measure components, and its capacity to help organizations fully leverage their data while maintaining robust security measures.
