One of the major points of n-tier design is to allow change of one component of an app without effecting the rest. What happens to your business rules if your client decides to change to another database vendor or decides that they want to run disconnected so you need to use XML? Which is another reason incidentally why a lot of people are using web services in there middle tier….

<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Much of the difficulty in this area focusses around the simple thought that wrong things may be attempted on the db. And that the DB should do some of the thinking for the application. So much of the logic applied server side is designed to sort that out.
</span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt"> </span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Is there any appeal to objective philosophical logic that points to any overall approach that spares us the intellectual burden of having to trouble shoot problems and that perhaps should not exist or matters that need to be solved serverside?
</span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt"> </span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Knuth and other early logicticians propose what became simply termed the "rubbish in rubbish out" principle. It seems that in flow dynamics it is better to sort rubbish out before it goes "down stream", so that you avoid having to send anything "up stream" calling for changes.
</span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt"> </span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Many people of that era thinking through this stuff held the thought that each isloatible unit should have its own integrity. Hance Knuth's TeX approach in page layout which is in its own way, the storage and qualifying of data. The format of TeX assumes though that the 'user' has already pre-processed the actual data and it is warrantable for deployment.

<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">So I have been thinking alot about this stuff from the view that each level of the process should only be passing 'data' on to the next that is in all senses pure and appropriate. Now people will immeadiatley say that can not work for multi-development-client applications utilising a common database.
</span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt"> </span></font></p></div>
<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">To that I would make the suggestion of a server abstraction layer which requires that an application must send a verifying "key" that asserts that the post has the integrity required by the standard set for the process. Not just a password alone, the purpose being to focuss the developer to implement internally all necessary requirements prior to posting. These requirements can available following the Java strategy pointed out earlier.
</span></font></p></div>

<div>
<p><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Perhaps then logic and checks db side should only be as minimal as possible - essential enough to ensure the basic integrity of the db is actually maintained.
