The document discusses data mining techniques in SQL Server Analysis Services (SSAS). It defines data mining as using artificial intelligence, machine learning, statistics, and databases to discover patterns in large datasets. The data mining process involves business understanding, data preparation, modeling, evaluation, and deployment. Common algorithms covered are decision trees, clustering, time series analysis, and association rules. Creating a mining structure in SSAS involves selecting a data source, specifying columns and data types, and deploying mining models.

What is Data Mining ?
• the computational process of discovering patterns in large
data sets involving methods at the intersection of artificial
intelligence, machine learning, statistics, and database
systems.
• The overall goal of the data mining process is to extract
information from a data set and transform it into an
understandable structure for further use.

Data Mining Process
• Cross-Industry Standard Process for Data Mining (CRISP-DM)
consists of six cyclic phases :
• Business Understanding
• Data Understanding
• Data Preparation
• Modeling
• Evaluation
• Deployment

Decision Trees
• Decision Trees
• a tree-like graph or model of decisions and their possible
consequences, including chance event outcomes, resource costs
• Very common, used for classification.

Clustering
• Clustering
• grouping a set of objects in such a way that objects in the same
group (called a cluster) are more similar (in some sense or
another) to each other than to those in other groups (clusters)
• Widely used in areas of fraud detection

• A time series is a collection of observations made chronologically,
Used to predict a number of some sort.

Association rules
• Association rules
• Association rules are if/then statements that help uncover
relationships between seemingly unrelated data in a relational
database or other information repository.
