Hello 

I am not an expert for database but rarely design database for Web and IVR applications.

Today I wonder if there is any practical advantage of inheritance of Tables.

Lets take the same example that is commonly referred.
CREATE TABLE cities (   name            text,   population      float,   altitude        int     -- in feet
);

CREATE TABLE capitals (   state           char(2)
) INHERITS (cities);

Capital table inherit attributes from Cities but no data. I am confused with concept of inheritance in postgres.
In These tables what i was supposing is inheritence as that in JAVA. but its seems to be  a different scene.

Can some one Please compare inheritence in JAVA and Postgresql OR make me clear about for what inheritance is introduced in Postgres.
