In Data Warehouse data is stored from a historical perspective. The data in the warehouse is extracted from multiple functional units. It is checked, cleansed and then integrated with Data warehouse system. Data warehouse used a very fast computer system having large storage capacity. This tool can answer any complex queries relating data.
A data warehouse merges information coming from different sources into one comprehensive database. By merging all of this information in one place, an organization can analyze its customers more holistically. This helps to ensure that it has considered all the information available. Data warehousing makes data mining possible.
The data mining can be carried with any traditional database, but since a data warehouse contains quality data, it is good to have data mining over the data warehouse system. Data Mining supports knowledge discovery by finding hidden patterns and associations, constructing analytical models, performing classification and prediction.
Data mining allows users to ask more complicated queries which would increase the workload while Data Warehouse is complicated to implement and maintain. Data mining helps to create suggestive patterns of important factors like the buying habits of customers while Data Warehouse is useful for operational business systems like CRM systems when the warehouse is integrated.
The link between data warehousing and data mining is that it is easier to mine data, which is properly housed meaning that the effectiveness of data mining is dependent on data housing. Consequently, data mining has the demerit that it cannot be effective without the existence of an integrated organisational information database.
Data mining tools and techniques can be used to search stored data for patterns that might lead to new insights. Furthermore, the data warehouse is usually the driver of datadriven decision support systems (DSS), discussed in the following subsection. Thierauf (1999) describes the process of warehousing data, extraction, and distribution.
Types of Data Warehouse. Information processing, analytical processing, and data mining are the three types of data warehouse applications that are discussed below Information Processing A data warehouse allows to process the data stored in it. The data can be processed by means of querying, basic statistical analysis, reporting using
