field: Fields describe a single aspect of each member of a table. A student record, for instance, might contain a last name field, a first name field, a date of birth field and so on. All records have exactly the same structure, so they contain the same fields.
Many jurisdictions require one or more bicycle lights to be fitted to bicycles ridden at night â generally a white light in the front and a red light at the back.
