Hi Gurus, please comment on this rant

Question

Hi gurus,
I got into a heated argument with a guy on the yahoo PowerBuilder group about which whether we should use existing database functionalities or PB functions. Of course each will do its own job in a better way. I gave an example in Oracle in which I said I can simply use select thisDate - thatDate from t to get the exact days to the fraction that I always need, whereas in PB I have to use daysAfter(date1, date2), plus secondsAfter(time1, time2) plus * this and / that. This guy is getting rediculous and mad and sent me the following comment:
"With Oracle being an expensive "per seat" database, I've had clients develop on another platform that's free or considerably less expensive..."
"All the database is is a repository for data, basically to logically relate data to other data. IT IS NOT and never was intended to be a processing platform but due to old machine limitations 20 years ago while mainframes (Unix based) were powerful, vendors saw that as a way to capture clients. Over the years, things change and DBMS vendors still hype stored procedures while in reality, they have little place any longer. PC's are fast and often faster than the servers the DBMS runs on, memory is dirt cheap and hard drives are huge. Not the case even 10 years ago let alone 20. The only DBMS vendor that has kept up with the industry IS Oracle. Sybase used to be bigger than Oracle but not the case even if one just considers only Oralce's database presence.
Most DBA's will tell you that stored procedures are not really viable anymore..."
Maybe Tom Kyte can teach him a good lesson!
Thanks.

Hi Rajan,
In your program you have to tune the program so that it takes litlle bit time.
In you all quaeries you used select *, if you requied all fileds of table , then it is OK.
otherwise create structure for each table whcih contanining the fields that u want in your quarries.
For example,
Types:begin of ty_makt,
          spras type makt-spras,
           matnr type makt-matnr,
          maktx type makt-maktx,
          end of ty_makt.
data:it_makt type ty_makt,
       wa_matk type ty_makt.
Like this u create internal table & work areas.
So this will reduce datbase fetching.
Also whereever requied use range
For exapmle:instead of  parvw in ('AG', 'WE') , use parvw in rg_parvw like this.
use sorted table with indexing for loop, It takes little time to run loop.
for example.
it_vbrp type sorted table of ty_vbrp with non-unique key vbeln posnr matnr,
  CLEAR w_tabix.
  READ TABLE it_vbrp INTO wa_vbrp INDEX w_index.
  IF sy-subrc EQ 0.
    w_tabix = sy-tabix + w_tabix.
Vbrp loop start *******************
    LOOP AT it_vbrp INTO wa_vbrp FROM w_tabix.
   ur coding
  endloop.
endif.
Or u can used hased tabel also.
Check  ur program with se30 tcode, check whether coding takes time or datbase fetching.
Then do tune the program accordingly.
