je Bilkul

a.a, plz dosto a jao sub discussion start kr kay ye assignment solve kr lain last day sub solution solution kr rahay hotay hain jin ko aati hay wo guide kr dain plz mil kr ho jaye gi a jayen sub members please

Any one share the ieda of cs614 plzzzzzzzzzzzzzzzzzzzzzzzzzz

Idea is very simple but uski samjh main ana hy js ne baki lectures liay huay hain .

Data Mart

  Departmental subsets that focus on selected subjects.

I try to explain with below diagramLet me recall your some of concept before Datamart

sb se pehly ap k pass production system hota hy jis main all time transaction ho rai hoti hain also called "OLTP"

for example you goto Hyperstart and buy something that data store in OLTP.

from here all data goes to Staging area jaha pe ETL(Extract, Transform, Load) ka process hota hy 

and after ETL your data goes to Datawarehouse.

sb ko itna to andaza hoga k DWH is big big database jis main har department ka data hota hy

now rather directly accessing data from DWH har department apna "Data Mark" bana leta hy isi liay as per definition "  Departmental subsets that focus on selected subjects.

so agar humary pass purchase, sale, inventory k data markts hain aur hum inko ikatha kar dain to wapis DWH ban jaey ga.

now all users, aur devices jin se reporting leni hy wo Data Mart Se commmunicate krain gy. 

For any confusion reply here. 

IMPORTANT : yes sb kuch oper se guzar gaya ho ga agar ap video lec nai lay rahy CS614 k. please ask question only if you are following handout OR videos or you have basic concept of data warehouse working

Additionally this will also help you understanding the cocnept

SK(MS-SE) Please ap apni f.b id tu shair karyn
