Home -> Community -> Usenet -> c.d.o.server -> New trend in modern IT consultancy - use your relational database as flat file
Greetings,
for last few years I can see a new trend in consulting companies. In the past they pretended that their people have some database knowledge. However, I think that this is too old fashioned and not enough sexy for them. So they started a new era in consultancy. In fact all relational theory is obsolete, DB architect position is obsolete and any other database related stuff is too boring for them. Up to date consultant should be proud that he has no database knowlegde, best applications have generated data model with tables like this (real world example):
T08000
T08000T002005_0: NUMBER T08000T007000_0: NUMBER T08000T005000_0: NUMBER T08000header___: VARCHAR2(4000) T08000footer___: VARCHAR2(4000) T08000T008000_0: NUMBER T08000attribs__: NUMBER
Of course there is no referential integrity (foreign keys slow things
down and we have all needed checks in our application), no triggers
(do not need them all logic runs on app server). Database model is
cyborg only readable, but that's no problem any more (you should never
access database with anything but our fancy DB access layer written in
JAVA). This DB access layer maps objects in application to tables and
rows within using some unique identifier, it basically means that all
range scanning of objects in database needs to be transfered to bunch
of single row querries (no problem at all we have great benchmark
numbers from SUN/IBM/HP/COMPAQ/MICROSOFT* test labs - * - check what
sounds you best). Developing company doesn't have a single DB
specialist (do not need them, just JAVA coders) and database layer has
no DB specific parts (our application can run on all database
platforms with no changes at all).
And on top of it, this approach is usually described as new trend in
IT and all previous development not using this madness is called old
fashioned or just 70s style.
What do you think about this? It seems to me that this trend starts to be very popular in J2EE world. I think one of the main reasons can be that this gaves a JAVA guy with no database knowledge feeling that he is not ignorant, but very progressive in the world full of relational reactionist.
