UNIT I DATA
WAREHOUSING (Expected questions DW architecture,multiprocessor,meta data )
Data warehousing
Architecture–-
Mapping the Data Warehouse to a Multiprocessor Architecture – DBMS
Schemas for Decision Support–Metadata.
UNIT II (Sure Questions from OLAP)
Reporting and Query tools and
Applications – Online Analytical Processing (OLAP) – Need
–Multidimensional Data Model – OLAP Guidelines – Multidimensional
versus Multirelational OLAP – Categories of Tools – OLAP Tools and the Internet.
UNIT III (Data
mining functionalities, issues,task primitives, preprocessing are important 8 Marks)
Data Mining Functionalities –
Classification of Data Mining Systems – Data Mining Task Primitives
–Integration of a Data Mining System with a Data Warehouse – Issues –Data
Preprocessing.
UNIT IV
(bayesian and decision tree are repeated questions)
Problem,classification by back
propagation,other classification methods,bayesian classification n rule
based classification,decision tree induction.
UNIT V
(In clustering types you can expect questions)
Cluster Analysis - Types of Data
– Categorization of Major Clustering Methods - Kmeans– Partitioning
Methods – Hierarchical Methods - Density-Based Methods –Grid Based
Methods – Model-Based Clustering Methods – Clustering High Dimensional Data
- Constraint – Based Cluster Analysis – Outlier Analysis – Data Mining
Applications.
Note:
1.When you study the Data Warehousing and Data Mining, study these topics and then move to some other topics what you feel as important
2. Most of the theory questions during the valuation they will see correct definitions,key points,sub headings,presentation....
3.Don't memorize all the points..
4.Write point by point
5.Study the given below topics and concentrate more on bolded topics
6.Try to study first half or second half of the unit…(for example if u study first half fully then take some imp question from second half..have a glance)
7.I can suggest you that don’t study like reading a novel. Take a note book and write down all the sub headings before you start the content.
