Attribute data with no associated .shp and .shx file

[Paul G. Allen]

At the risk of sounding stupid...

I just realized the my Street Address and Zip code .dbf files have no associated
.shp and .shx file - the streets themselves have a separate shapefile. The only
reference that ties the two (address/zip code and street) together is a matching
ID number in each .dbf file. How would I go about placing the addresses on a map
in the correct places? How would I go about placing the addresses in a set of
query results of a street(s)?

Thanks,
