CDISC Foundational Standards are the basis for the complete CDISC suite of standards, supporting the clinical and non-clinical research process from protocol through data collection, data exchange, data management, data analysis and reporting. These standards focus on the core principles for defining research data standards applicable to most research studies, and include models, domains and specifications for data representation. CDISC Foundational Standards can be freely accessed by the global research community by clicking the appropriate blue button in the top section of the diagram above.
