[AccessD] The Famous Bound/Unbound Debate

A lot of it was JC and I sparring.  LOL

I guess the essence is that bound/unbound is a 180 degree difference in
the approach of developing an application.

Bound forms in Access handle a metric ton of things automatically.  So
you are starting with a ton of features, and functionality, and end up
limiting, tweaking, or removing functionality.  

Unbound forms are the polar opposite.  There is not functionality at
all, you have to build everything you want to do from the ground up.

Bound design: 
Pros: Quicker to develop with instant functionality. Can be less code
intensive (depending on how much customization is done).  Access does a
lot of work for you.
Cons: More cumbersome from a mutli-user networked app.  If you need a
light weight form, you spend more time limiting functionality.

Unbound design:
Pros: Inherently more light weight.  Special functionality can be built
into, instead of on top of.
Cons: Longer development time.  More code intensive.  You replicate work
Access would do automatically in a bound form.

One big trigger to the debate was database/application design
preferences.

JC just brought up his 'call center' application, and a while back, we
had a discussion about one element of that application.

It was in a 'memo' field.  Let's say we had to track calls coming in to
a support center.  We'd have fields for caller, tech, date, time, issue,
categories, etc.  And a memo field for details not put into more
specific fields.

In a bound method, that memo field would be just that, one field, in a
table.  So as notes are 'added' to a ticket, you are modifying one
field, in one record.

In an unbound method, that memo field would be a separate table, with an
ID field linking back to the original table.  Each entry would be
timestamped (and stamped with the creator of the record).  You wouldn't
edit a 'comment', simply add a new entry.

There are pros and cons to both methods.

All,

Compared to most of you, I am a relative newcomer to the world of
Access.

Over the past few months, I have noticed a number of references to the
Bound/Unbound debate.  It sounds like this was a really hotly contested
issue at one time and that now people almost joke about it.

For us newcomers, it would be nice if someone could explain this issue
at a high level and perhaps spell out the major pros and cons of each
side of the debate.

It is not my intent to start a Web-war, I would just like to better
understand what is going on here.

Thanks,
Brad
