Best way to produce reports if the data model is in RDBMS

Question

we have database available in RDBMS.we will have to create reports out of that database.
Anyone suggest me best way(by considering all the factors) to get the reports if database is in RDBMS.
what are all need to follow in physical layer and what are all need to follow in BMM layer.

Answer 1

Thanks saichand for the response.
Ex: lets say,if there are 25 tables in the database(in RDBMS,there are lot of joins exists between the tables like A->B->C->D->E->F->G->H, in this case if report is from A,E and G then which way i will have to create view in the physical layer)
i have arrraged tables and columns below for better understanding
A B c D E F G
A1(pk) B1(PK) C1(PK) D1(PK) E1(PK) F1(PK) G1(PK)
A2 A1(fk) B1(fk) C1(fk) D1(fk) E1(fk) F1(fk)
A3 B2 C2 D2 E2 F2 G2
from the above tables and columns,if the report should be with A1,E1,E3,G1,G2 fields in that case how to create view in the physical layer.
for each and every report do we need to create seperate view?
can you please elaborate the procedudure in different situations?
Thanks in Advance.
