Last night someone asked about objects in relational databases. I asked
someone here about it.
Below is from one of our Oracle 9i people:
===================================
Yes, you are correct. Objects & Methods for that objects can be defined in
oracle.
here is an example.
CREATE TYPE PointType AS OBJECT ( x NUMBER, y NUMBER );
CREATE TYPE LineType AS OBJECT (
end1 PointType,
end2 PointType,
MEMBER FUNCTION length(scale IN NUMBER) RETURN NUMBER
);
/
you can create normal relational tables having an object as one of its
column.
Hope the above thing would've given u a little bit idea of what we can do.
===================================
Like so much else, I take his explanation as a starting point. More later.
Now as to objects in programming:
An object is a combination of instructions and data.
I'm still trying to grasp it all but it helps when I try to explain it, I've
found.
