Data Modules - not a question
lazarus / 16-Databases

As i progress further with my learning of Lazarus (no Delphi or OOp
Background) - I discovered DataModules.  Its amazing, every time I
find a 'solution' to a need, and the query a small issue, i find a
solution was there in  another component.

My Application has a Database with many related tables.  Rather than
have an 'enormous' Form1, I started creating several Forms with the
SQL access for each of the accesses i needed.  The forms were never
displayed - it was just a way to group the related routines together.

By putting the access into a datamodule achieved the same without the
confusion of an 'unused' Form.  Not sure if it achieves more in
reality, but it certainly seems far 'neater'.

My biggest 'complaint' with Lazarus ...   is there is so many
components ...   and finding a needed component (for a newbie) ... 
 usually happens after having a problem re-inventing the wheel.

I'll get there eventually - and please dont take this a complaint -
its just an  observation.

I understand how you feel. Please feel free to update the databases
wiki documentation...

I haven't seen much if anything about datamodules there.

OT: So you've gone the OOP path after all instead of low level db
access? Good choice

I'm not sure if I'm qualified to update or create Tut4. but i will
create a draft if you would kindly proof read (after I have learnt
more from my mistakes   And yes, I am trying to learn the OOP way, but
also learning the basics at the low level.  Learning the low level is
a great way to understand and learn what the higher level  is doing;

Just throw it up there and I'll gladly have a look.

Good luck!

I created a wiki account, but there is nothing obvious, like 'create a
new page' - so need your help again BigChimp.

Thanks

Yes, that works a bit strangely (in all wikis). You can just type the
name of the page you want to create in the search field, then you'll
get an error the page does not yet exist... but you can create the
page with that name.

For more details: see the main page wiki page, IIRC, there's a link to
a wiki guide.
