Question 3 Performance:


the physical structure of the data warehouse specially optimized for completely random samples, which allows you to build really fast query system.

specific logical organization of storage and there are specialized software allows the creation of analytical systems with minimal programming.

integration of data from different sources has already been done, so it is not necessary each time to make a data connection for the query requires information from multiple sources.

OLTP-systems operate with current data, the period of use and storage of which is typically less than the current value of the business - period (six months - a year), while the data warehouse data is aimed at long-term storage of information in the next 10-15 years.

Analysis of Information repository significantly reduces the load on the system OLTP-side analytic applications, and performance of existing systems is not getting worse, but in practice there is a decrease response time and improve system availability.
