Hi,

I recall that BCB or delphi, (not sure which), has a data module.
 Where you can drop your data access components, and then access them
from whichever form you are on.

Is there something similar in Lazarus?

I know for sure that Delphi has a datamodule, this was introduced in
Delphi2. I guess BCB will have a datamodule as well, as the IDE and
compiler are really the same.  Your question is about Lazarus so:
Lazarus does have a datamodule, but ...
In design time it is not (yet) possible to link a datasource on your
form to a dataset on your datamodule. You can assign this during
runtime.

In short, you can use a datamodule to put all your data-access logic
together in one place, the connection between your data-access and
your gui you have to make during runtime. For instance like this:
Code: [Select]
uses
  U_with_Datamodule;
procedure TForm1.Create(Sender: TObject);
begin
  myDataSource.DataSet := myDataModule.myDataSet;
end;

Thanks... So I basically create a

What is the highest priority improvements on lazarus?

I guess there are several people working on several different things
at the moment.  I might be able to give a hand, but I wouldn't know
where to start.
