[DUG] OO Programming

[Steve Peacocke]

Yea, thanks Conor,

Sure, in RAD, as it is in any Delphi project, you can certainly get away
with simply programming the event handlers in the components (depending on
the application). That should not preclude being able to create, for
example, an Application Object that handles all your globals like the logged
in user, or the company name and other details needed at times (e.g.;
lbCompany.Caption := oApp.CompanyName) - where perhaps the company name is
extracted from the database etc. In this example, oApp knows how to extract
the company name, and perhaps even format it for display.

RAD does not mean ShiteProgramming, or NoThoughtProgramming. Its hard to
find a definitive definition (?) for RAD and a quick search shows various
descriptions from the tool itself (Delphi or VB) to the whole spectrum of
Agile methodologies.

However, I do disagree with the assertion that RAD does not lend itself to
larger apps (or did you mean "Rapid Prototyping"). In fact RAD is an
excellent development environment for developing even enterprise level
applications. Some years ago I had the pleasure of working in a team of
between 3-5 developers where we used a RAD approach (using Delphi) in an
iterative and incremental development methodology to produce a very large
scale corporate application and can confirm the approach as excellent and
the development far outperforms a team up to 10 times larger using Java/J2EE
in a refined waterfall approach for a similar sized project.
