Slowly Changing Dimensions


Updating and inserting records into a data
warehouse dimension tables
Type 1
–

Type 2
–

New changes will overwrite existing data
New changes create new records instead of
updating existing ones. Will change date to
indicate current or expired record.
Type 3
–
Limited historical data; add columns for “old”
value, update “new” data
Data Mining

The process of identifying patterns in data

Goes beyond simple querying of the database

Goes beyond multi-dimensional database
queries as well
Data Mining

Data Mining works for problems like:
–
–
–
Develop a general profile for credit card customers
…
Differentiate individuals who are poor credit risks
…
Determine what characteristics differentiate male
& female investors.
Data Mining vs. Data Query


Use data query if you already almost know
what you are looking for.
Use data mining to find regularities in data
that are not obvious.

How does Data Mining work?

Uses induction-based learning:
The process of forming general concept
definitions by observing specific examples of
concepts to be learned.
