Hi,
I need to develop a database table that will aceept a variable array
field. My doubt is how to deal with updates on the
array field. How can I store the information of the array fields?
There any examples on the Internet on how to deal with
this subject?
What I mean with variable array is:
array(
'name' => 'Don',
'age' => '31'
);
array(
'name' => 'Peter',
'age' => '28',
'car' => 'ford',
'km' => '2000'
);
thats very non-relational, and will make queries and updates very
difficult and messy, as well as making data integrity impossible to enforce.
is there a predetermined number of attributes, even if they may not be
present for a given entry? I would have a Person table which has all
the fields that most/all persons would have, like persons(id, name, age,
address, phone, etc), then for optional attributes a seperate table for
each attribute collection like car(person_id, brand, model, mileage,...).
