By comparison to the common handling of office forms and files, it is argued that 1NF relations are sufficient representation only for precise data organizations: data organizations which are declared to represent fixed types of data, with fixed relationships between the data, and where all data added meet the preconceived expectations. A limited class of non-1NF relations are suggested to represent an imprecise database which admits exceptional conditions to a data organization. An imprecise view navigation system is described to allow unsophisticated users to access the imprecise database. Such a database system would interact with the user more affectionately than so-called 'user-friendly' systems.
