Data management refers to creating, saving, updating, making available, archiving and long-term storage of research data. The final goal of this process is often defined in terms of the FAIR principles: 'Findable, Accessible, Interoperable and Re-usable'.
This involves thinking carefully, before you start collecting or creating data, to make sure that your data is findable, accessible, interoperable and re-usable. Not only for others, but also for your own future use.
