Data is a very complex term to define because it does not exist independently of the ideas, instruments, practices, context and knowledge used to generate, process and analyse it5. However, many accept that data is the elements extracted through observation, computations, experiments and record keeping6. They include network, asset, weather and organisational data7. This book will refer to personal data when it means data about an individual, but otherwise personal data is excluded from our usage.
