What needs reporting?
 Ideal approach is to extract the required reports
from a “business reporting model”
 What is a business reporting model in essence it
has two parts:
– What we want to add up?
– What we want to analyse by?
 So how do we go about getting the requirements
right?
10
Will this “Business Reporting Model” Work
 We create the “business reporting model” simply
on a flip chart,
 Then we walk thru the model to see if we can
get the reports out!
 Simple, really!
 Here is how we do it …using Motorcar Insurance
11
What will this model look like?
What we want
to add up?

… now for a worked example
12
What we want to Add Up?
•Premium
•Claim
•Loss Ratio [Claim/Premium]
 Typical questions:
– How much premium did we
collect?
– How much claims did we pay?
– What Loss Ratio are we
running at?
… so now lets see what we want to analyse by
13
What we want to analyse by?
•Premium
•Claim
•Loss Ratio
[Claim/Premium]
Analyse by Time
Analyse by Car
Analyse by Customer
Analyse by Broker
Analyse by Geography
 Typical questions:
– What is the average
age of drivers?
– What models of cars
do we insure?
– What is the longest
policy period?
– What locations do we
insure?
– Who is the top broker?
… so now lets join things up
14
Now we can ask better questions
•Premium
•Claim
•Loss Ratio
[Claim/Premium]
Analyse by Time
Analyse by Car
Analyse by Customer
Analyse by Broker
Analyse by Geography
 Typical questions:
– What location is the
worst insured area
based on claims paid
for the 2007 year?
– What colour car in
London driven by
males is the most
profitable in terms of
Loss Ratio?
– Who are our top ten
brokers based on
Premium for last year?
– What is the premium
trend over the last five
years in terms of
Geography?
15
More detail on Analyse by Time
•Premium
•Claim
•Loss Ratio
[Claim/Premium]
Analyse by Time
 Each of the items is a level, these levels allow you to group up the
data for example
 Year 2007
– Quarter 1 – 2007
– January 2007
– 01/01/2007
» 01/01/2007 12:00:00
16
Now we will look at some of elements in a little more detail, What we want
to Add Up?
 What we want to Add Up?
– Things like Premium and Claim are measures
– Things like Loss ratio (Claim/Premium) are
calculated measures
– By default measures are usually additive but you can
do other domain aggregate functions such as
average, count etc.
– We store them in the database as facts, because
that’s what they are facts about an action
17
Now we will look at some of elements in a little more detail, What we want
to analyse by?
 What we want to analyse by?
– We call the “analyse by” a dimension
– Levels within the dimension allow the facts to be
grouped up and summarised
– The groups are called hierarchies
18
What have we done?
 We have created a dimensional model called a
star schema
 It contains facts and dimensions
 We now have a business reporting model that
can be easily

  • 9. 9 What needs reporting?  Ideal approach is to extract the required reports from a “business reporting model”  What is a business reporting model in essence it has two parts: – What we want to add up? – What we want to analyse by?  So how do we go about getting the requirements right?
  • 10. 10 Will this “Business Reporting Model” Work  We create the “business reporting model” simply on a flip chart,  Then we walk thru the model to see if we can get the reports out!  Simple, really!  Here is how we do it …using Motorcar Insurance
  • 11. 11 What will this model look like? What we want to add up? Analyse by Analyse by Analyse by Analyse by Analyse by Analyse by Analyse by Analyse by … now for a worked example
  • 12. 12 What we want to Add Up? •Premium •Claim •Loss Ratio [Claim/Premium]  Typical questions: – How much premium did we collect? – How much claims did we pay? – What Loss Ratio are we running at? … so now lets see what we want to analyse by
  • 13. 13 What we want to analyse by? •Premium •Claim •Loss Ratio [Claim/Premium] Analyse by Time Analyse by Car Analyse by Customer Analyse by Broker Analyse by Geography  Typical questions: – What is the average age of drivers? – What models of cars do we insure? – What is the longest policy period? – What locations do we insure? – Who is the top broker? … so now lets join things up
  • 14. 14 Now we can ask better questions •Premium •Claim •Loss Ratio [Claim/Premium] Analyse by Time Analyse by Car Analyse by Customer Analyse by Broker Analyse by Geography  Typical questions: – What location is the worst insured area based on claims paid for the 2007 year? – What colour car in London driven by males is the most profitable in terms of Loss Ratio? – Who are our top ten brokers based on Premium for last year? – What is the premium trend over the last five years in terms of Geography?
  • 15. 15 More detail on Analyse by Time •Premium •Claim •Loss Ratio [Claim/Premium] Analyse by Time  Each of the items is a level, these levels allow you to group up the data for example  Year 2007 – Quarter 1 – 2007 – January 2007 – 01/01/2007 » 01/01/2007 12:00:00
  • 16. 16 Now we will look at some of elements in a little more detail, What we want to Add Up?  What we want to Add Up? – Things like Premium and Claim are measures – Things like Loss ratio (Claim/Premium) are calculated measures – By default measures are usually additive but you can do other domain aggregate functions such as average, count etc. – We store them in the database as facts, because that’s what they are facts about an action
  • 17. 17 Now we will look at some of elements in a little more detail, What we want to analyse by?  What we want to analyse by? – We call the “analyse by” a dimension – Levels within the dimension allow the facts to be grouped up and summarised – The groups are called hierarchies
  • 18. 18 What have we done?  We have created a dimensional model called a star schema  It contains facts and dimensions  We now have a business reporting model that can be easily
