Topic: Tables in MVD

Hello Dimitri

When creating New tables, question is asked : "the table is a dictionnary".

Do you mean that a dictionnary table is a hash table as Delphi knows it, that's to say  hash table is optimized for lookups (best speed) ?

Please, could you create a video lesson about interaction between  tables (as in PhoneBooke Example). It is not so obvious.
For example, i'm creating an application for my comics. I would use comboxboxes for drawers, scenarists, coloristes, gender, state ... and son on. Tables Drawers, Scenarists, Genders, State ... have been created. It's a lot difficult to understand how associate those tables with the main table (called Comics) so that comboboxes show various drawers, scenarists, gender ....

Thanks for your help and greats for MVD

Re: Tables in MVD

Hello,


I find it hard to define what is "the table is a dictionnary"
It's tables like gender, city, country, not necessary to use this option, necessary in rare cases.


In video lesson about Phone book you can find all the necessary information about the relationships.


Here you can read some info about One-to-many relationship
