Data collection

Data is normally collected as part of a defined research project, in which a limited number of questions are to be addressed through the collection of a specific set of samples and data (or just data alone). Data can also be generated as part of the ongoing activity of a biobank, where a collection of human-derived samples and data may be used to address any number of questions across a range of projects. Additionally, data can be collected through health services or government departments for use in healthcare planning.  

Where data is to be collected for research purposes, in most cases ethical approval is required to undertake the research itself and (in general) participants must give their consent to be part of the study (or studies) in question.
