Terminology, Coding and Classification - an insight into the methodologies available for capturing data in a structured form that is amenable to electronic manipulation. Capturing free text unfortunately achieves not very much: the data is not automatically for analysis, nor for aggregation, research or management. Using structured systems for data capture, based on systematic approaches to classification, radically changes the qualities of the data, as well as its availability for other processes and applications, such as analysis and expert systems.
