[Geotools-gt2-users] Feature, FeatureCollection, table

[ben h. a. <aym...@ya...>]

hi,
i'm confused about the meaning of a Feature. Does it represent  a table in a Postgis database or a spatial entity like point, ligne...
A layer does represent a FeatureCollection(= table)?
what i want to do it's extracting data from Postgis database and visualize it 
regards
