Projects and case studies

What are the various tools used in ETL?
Below are the most popular tools:
• Cognos Decision Stream
• SAS Enterprise ETL server
• Oracle Warehouse Builder
• Business Objects XI
• SAS business warehouse
What are the types of data warehouse applications?
The types of data warehouse applications are
• Info Processing
• Analytical Processing
• Data Mining
What is the difference between data mining and data warehousing?
Data warehousing is the process of aggregating data from multiple sources into one common repository whereas data mining can be defined as the process of extracting hidden predictive information from large databases and interpret the data while data warehousing may make use of a data mine for analytical processing of the data in a faster way.
What is transformation in ETL?
In ETL Transformation can be of two types. The types are Active and passive Transformation. It is a repository object which generates, modifies or passes data.
What is data source view?
A data source view allows defining the relational schema which will be used in the analysis services databases. Rather than directly from data source objects, dimensions and cubes are created from data source views.
