Data Subject

Any data collection technique that gathers information automatically, with or without the end user’s knowledge.

Data lacking a pre-defined model of organization or that does not follow one. Such data is often text-heavy, but can also include facts, figures and time and date information. The resulting irregularities and ambiguities make unstructured data much harder for programs to understand than data stored in databases with fields or documents with annotations. Many estimates claim unstructured data comprises the vast majority of global data, and that this category of data is growing rapidly.
