INTRODUCTION
Data Mining
We use OLAP technology to view data in interactive way in order to understand the decision making process.
From Past years systems are predominately using front end tools used in data warehousing environments and OLAP system’s market grew rapidly.
Many Data Mining techniques like association, classification, clustering, can make OLAP more useful and easier to apply in decision support systems.
Previous Work
Schema generation was considered as manual task but we will automatically represent it.
In Previous work Schema generation was never integrated with data mining.
Here we are going to use the famous data mining technique: Hierarchal Clustering
Combining OLAP with Data mining
This technique is used to identified frequently used web pages and to discover the hidden patterns.
To analyze large amount of data in efficient manner.
Flexible and multilevel rule mining
Automatic OLAP schema Generation
In order to Integrate data mining results with OLAP the data has to look in particular schema type.
Schema is collection of database objects, Tables, views, indexes etc.
Here using tools we generate the all three types of schemas
