This is my first post as a Qlikview BI Student. I have read so many content about data warehousing and their structures, OLAP,star schemas, snowflake schemas, fact and dimension tables e.t.c I have also practised the online lectures. I quite understand what BI and BW is all about. I also understand that a cube can have more than one fact table. I have this relational database model which is i got from one of the qlikview online tutorials. I would be happy if anyone can convert the relational model to a star schema model. I don't mind if you provide more variations of the star schema , such as modelling it to have more than one fact tables. Please click on the image below to see a bigger version. Thanks.
Hi!
Write script like this (pseudo code):
Fact:
Load *
From Orders;
Join
Load *
From OrderDetails
Join
Load *
From Shipments;
Join
Load *
From Shipper;
Customers:
Load *
From Customers;
Join
Load *
From Division;
Products:
Load *
From Products;
Join
Load *
From Categories;
Load also calendar, offices, employees and suppliers. Maybe you can map suppliers to fact -table. You can also join offices and employees.
Above will produce reasonable star schema.
