I have a database that should be quite simple to do.
I have a base object that is easily defined
as
create table myObject (
a integer,
b integer,
len integer,
data bytea
);
Now this really should be a type:
And oddly enough it is the only type of data in the entire database.
A list of these is a row in a table.
The list size is variable.
level a one to many level b
level b one to many level c
level c one to many level d
Each of these levels is a list (or row) of these objects..
What does the scheme or sql of this look like.
I'm sort of new to databases.. but I don't know how to make the 'entity
relationships' between the levels.
Help?
