cleansed, transformed, and structured
to meet the requirements of data mining
Data Mining
Data mining algorithms are applied to
the prepared data, uncovering patterns,
insights, and relationships.
Data Visualization

Overview of Data Mining Techniques :
Classification
This technique categorizes
data into predefined classes,
like identifying fraudulent
transactions or classifying
customers based on their
purchasing behavior.
Regression
Regression analysis predicts
continuous values, such as predicting
future sales or estimating customer
lifetime value.
Clustering
Clustering groups similar data
points together, enabling
businesses to identify customer
segments or discover patterns in
product usage.
Association Rule Mining
This technique discovers
relationships between different data
items, uncovering patterns like
"customers who buy product A also
tend to purchase product B."

Data Warehousing Concepts and
Architecture
Data Warehouse
A data warehouse is a centralized
repository of integrated data from
multiple sources, optimized for
analytical queries. It provides a
single, consistent view of the
organization's data.
Data Mart
A data mart is a smaller, focused
subset of a data warehouse, tailored
to a specific business function, like
marketing or finance. It simplifies
data access and analysis for specific
departments.
ETL Process
Extract, Transform, Load
(ETL) is a crucial process
that extracts data from
various sources, cleanses
and transforms it into a
consistent format, and loads
it into the data warehouse or
data mart.
