Re: DB Maintenance Design Patterns

Kevin and Henrik

I suggest you both buy any good book on best principles of web application
design (including jQuery and JavaScript libraries) and also study your local
law! Currently an application should be usable without JavaScript (or even
CSS) and then progressively enhanced for the vast majority of users (without
forgetting the minority). I should not have to point this out but this is
actually law. True it is very difficult especially with the race for client
side Ajax Apps (but it IS possible and those doing it will be successful). I
am not claiming I will be one of them but at least I am aware of it and I do
try.

And Henrik I do not confuse anything with Java plug-ins (I've never used
Java in my life and I expect I never will!). Please do not insult me again!

Why would anyone turn off JavaScript support these days though - unless they
don't have any interest in using the Internet? Turning it off would
preclude you from using almost every modern website there is.

I guess the point is, why would Nathan need to demonstrate his example
working without JavaScript support? That would be almost as pointless as
demonstrating it without CSS support.

Lack of a mouse, on the other hand, is a valid point. You should be able to
navigate to any clickable element with the keyboard and hit enter to trigger
the event - but that requires JavaScript :)

Can you name any browsers in use these days that do not have
JavaScript
support?

Of course all modern browsers support JavaScript, but they also (or at
least most of them) allow it to be turned off for users who wish to do
this.

I do believe it is connected with "accessibility" although you may
wish to check that! (or have we thrown accessibility out of the
window?)

Supposing you had 10,000 product records. Can you show us how paging
and search functions are implemented in your pattern? Then there is
the issue of usability, progressive enhancement etc for those users
who do not have JavaScript or mouse support?

Kind Regards

I discovered the source of the problem with the link I posted a
couple days ago, and fixed it. Again, my apologies for the inconvenience.

I throw this out as a pattern for database maintenance that is
efficient, effective, and productive from an end-user's point of view.
It seems that the vast majority of browser based DB maintenance
interfaces that one sees in the wild are rather primitive in comparison.

Many of the mouse and keyboard options may not be apparent at first
blush.
But once you become aware of them, they are quite handy and helpful.
For example, try Ctrl-Click to select multiple rows, then press F2 to
activate "Change" mode.
