Attaching Auxiliary Data
Various navigational functions, involving active safety, driver assistance and location-based services require data that is not considered to be part of a map database and is likely supplied by a vendor other than that of the map provider. Such data needs to be cross-referenced with the entities and attributes of the main database. However, since the auxiliary data is not necessarily compiled with the main database some other means is needed to establish cross-referencing, which is referred to as attaching the auxiliary data. Two common approaches are function-specific referencing tables and generic referencing.

Famous quotes containing the words attaching and/or data:
“It is no small mischief to a boy, that many of the best years of his life should be devoted to the learning of what can never be of any real use to any human being. His mind is necessarily rendered frivolous and superficial by the long habit of attaching importance to words instead of things; to sound instead of sense.”
—William Cobbett (1762–1835)
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
