From the article:
"Valentina does not require the creation of KEY fields - you can avoid the
headache of filling in unique values.
Each Valentina Table has a special RecID field, which provides a unique
number for a record of this table.
...
To establish the all important M:M link between these two tables, Valentina
offers a very special feature: the BinaryLink.
CREATE BINARY LINK PersonPhone(Person, Phone)
AS MANY TO MANY
...
Versus Primary Keys. RecID fields do not consume any disk space. Compare
this with a primary key with associated indexes.
...
If designed with the native Valentina Object-Relational way, you would
execute the same query with Valentina:
SELECT *
FROM Person JOIN Phone"
Okay, yeah, but nothing is free.
SOME space SOMEWHERE on the disk is being used to store those invisible
RecID values.
And, what special hoops do I have to jump through in my code during data
entry so that Valentina knows WHICH phone goes with WHICH person?
It sure isn't going to guess it unless I follow a pretty strict protocol
for the data entry.
