import id

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 2.5.28
-- PHP version -- : 5.x

Hi
I have no issue at this time and it is a general question about joomla and also hikashop since all extension related to component ( new object type ) need to implement their ow way to import /export data ( don' t no if it is exact, it is how i understand joomla ecosystem until now )
I look at php and sql to learn api and I see that joomla and hikashop table use for many ( all ?) columns name the word id ( suffix/end ) and the type of this column is int(11) unsigned . S§ome hks table contain only column with id for mapping only ( and few others column name so hard to understand line of number without label title name !!!) .

0) When i export from database1 and import in database2 ( data or extension ) ., Does joomla on database2 can map all the inter relation id that ll be added during import in database2 ?. In many case id is auto increment so some id value could not be import ( id already use) and value should change . I think recommandation for prevent this behaviour is start from empty table but even extension use id ( problem if css selector use id value !!!) .

1) How joomla and hikashop match all the id ? I think transfert extension ( sp transfert for joomla and specific tool for hks ) could be a way so it is a kind or copy without care of preexist id ( ll be replace) !! Is there tutorial about id hell (if his kind of problems exist in joomla an also in hikashop and is use to refer to microsoft dll hell version NUMBER even it can write css id it aigue ) .

2)How mass action manage those id value during export database1 import database2?

3) Is there functionnalities ( or tutorial) in joomla that take care of consistent interrelation beetween id than exist in all extension ( hikashop product) / data ( product instance ) ?

4) does joomla support import export functionnalities in it core ( extension install by default in joomla ) accessible in the backend and enable by default ?

5) can we export import the data and the setting in each extension easely using rdbms ?

6) Does it mean all joomla extension gui backend for import /export are vaporware ( for people who know rdbms sql format structure BOM unicode ETL ) ?

I ll study the question but best is understand php , joomla before hks imort export ( xml csv json ) !!!

I think tjis link give a good way to process for others extension instance ( data setting )
