Hi,

I'm building adaptators for DB components in order to not modify my
application if I choose SLQB compoents or zeoslib.So I use a factory
class to bluid a TDatabaseManager with only a generic interface,
without any referencesto  specifics types from SQLDB or zeoslib
techicals libraries. Si this my DAO généric class using the factory
and manager TDatabaseManager :

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i IDAOClasse
= specialize IDAO<TClasse>; TDAOClasse = class(IDAOClasse)private 
sgDbm : TDatabaseManager;public  constructor Construire(dbm :
TDatabaseManager);  destructor Detruire;  function Ajouter(const obj :
TClasse) : TClasse; override; // Ajoute un nouvel objet T  function
Instancier(const id : integer) : TClasse; override; // Lire un objet T
existant  function Collection(strSQL : String) : TDataset; override; 
function Sauvegarder(const obj : TClasse) : TClasse; override; //
Mémoriser un objet T  procedure Supprimer(obj : TClasse); override; //
Supprimer un objet T end;
My question is about the method :

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   function
Collection(strSQL : String) : TDataset; override;
If I use zeoslib inside the implementation of TDatabaseManager, I will
use a TZQuery with TZAbstractDataset. Do you think it will be
compatible with a TDataset result ?
