D7 Database explained

Hi All,
Where can I find Dolphin 7 database explained, so that I can consider it while write my own module?
Some explanation for use of default D7 tables along with their columns.

Urgently I need to know use of 'parent_id' column in table 'sys_menu_admin'

Thanks!

There are no docs on the D7 Database. What most of us here know we got from studying the code and from trial and error.

To answer your current question. The parent_id contains the id of the menu item the current item belongs to. A parent_id of 0 means it is a top level item. A parent_id > 0 is a sub level item. It this case it contains the id of the top level item it appears in.

thanks deano92964,

hope boonex people are working on documentation, coz ease of module writing is surely going to make D7 more popular among developers as it will help them to create more quality n user friendly modules.

thanks once again :-)

I'm not one to even begin to think about treading on deano's answers, but there is some help - if you haven't seen it.

As deano said, you aren't likely to find database answers - but - I'm posting the link in case you didn't find it previously
