Research Data Management (RDM) is "how you look after your data throughout your project. It covers the planning, collecting, organising, managing, storage, security, backing up, preserving, and sharing your data and ensures that research data are managed according to legal, statutory, ethical and funding body requirements."
(Whyte, A. & Tedds, J., 2011).
RDM occurs in every stage of the research lifecycle, not just at the end, where all the data files are zipped up in a folder for storage.
