Table 5–1 (Cont.) Attributes for Formal Address Representation
Address Attribute Description
Street Street address, including the house or building number, street name,
street type (Street, Road, Blvd, and so on), and possibly other
information.
In the current release, the first four characters of the street name must
match a street name in the geocoding data for there to be a potential
street name match.
Settlement The lowest-level administrative area to which the address belongs. In
most cases it is the city. In some European countries, the settlement
can be an area within a large city, in which case the large city is the
municipality.
Municipality The administrative area above settlement. Municipality is not used for
United States addresses. In European countries where cities contain
settlements, the municipality is the city.
Region The administrative area above municipality (if applicable), or above
settlement if municipality does not apply. In the United States, the
region is the state; in some other countries, the region is the province.
Postal code Postal code (optional if administrative area information is provided).
In the United States, the postal code is the 5-digit ZIP code.
Postal add-on code String appended to the postal code. In the United States, the postal
add-on code is typically the last four numbers of a 9-digit ZIP code
specified in "5-4" format.
Country The country name or ISO country code.
Formatted addresses are specified using the SDO_GEO_ADDR data type, which is
described in Section 5.2.1.
An unformatted address is described using lines with information in the postal
address format for the relevant country. The address lines must contain information
essential for geocoding, and they might also contain information that is not needed
for geocoding (something that is common in unprocessed postal addresses). An
unformatted address is stored as an array of strings. For example, an address might
consist of the following strings: '22 Monument Square' and 'Concord, MA 01742'.
Unformatted addresses are specified using the SDO_KEYWORDARRAY data type,
which is described in Section 5.2.3.
