I think any sensible person will agree to your second paragraph..
There is also the 'flip side' where the vendor code is like 'scripture' and can't be modified by the unwashed ('the DBA'). UnQuote
If some code is not functioning proprely, then it should be changed..but this kind of mentality is developed when there is lack of documentation and the courage to change the code if it is need to change at that time..If your users are facing errors and you still think it can not be changed..then whats the use of such application..actually we used to have a team to take the feedback from endusers about whether they are facing any errors in using the application, do they require any new feature..and or do they want any other areas that can be bring under this application..
About change in code,Actually everybody including an enduser is also entitiled to recommend the change he/she wants..finally the code is meant to run the application..so that the enduser can work and or apply in day today life..not to remain the idle code in the application. Ofcourse the enduser will always speak his/her language..that is why you have SPRs..we used to have meetings on SPRs and also used to communicate the concerned person..
Lack of proper understandng, poor logical thinking, lack of courage to change develops this particualr attitude... In India we say 'Baba Wakya Pramanam' means I am doing this cause my forefathers have told me to do so...is useless..in todays era like it was in ancient era too..
lets hope that following will happen..especially 'he who shall remain nameless'
And application code isn't the only victim in this; we've been fighting a battle with 'false facts' about Oracle for years and it seems as though the battle is slowly being won as the influence of 'he who shall remain nameless' is diminishing; let's hope this trend finds its way into the application realm so that some day the sun will shine, the birds will sing, water will be pure, bind variables will be abundant and queries will never need tuning. <play "Happy Working Song" here> UnQuote
If you are using any application interface then the fields acts as bind variables..no alternatives to this...and using a database just by SQL is not correct way..it will affect the databse affect itself because of the architecture itself..performance and sometimes availability also..and this is why a 'userfriendly' application is developed with proper practices of QA/QC..all the six-sigma, CMM-lelvels, ISO, ITIL-V3 are to maintain 'userfiendlyness' not to add the 'cherry on cake' of certain DBA, team member and or certain company;s profile :)
my two cents..:)
