Study Material, Lecturing Notes, Assignment, Reference, Wiki description explanation, brief detail, Integration of a Data Mining System with a Database or Data Warehouse System. A data warehouse is constructed by integrating data from multiple heterogeneous sources that support analytical reporting, structured and/or ad hoc queries, and decision making. and query processing methods of a DB or DW system. For example, if we classify a database according to the data model, then we may have a relational, transactional, object-relational, or data warehouse mining system. Tight coupling means that a Data Mining system is smoothly integrated into the Database/Data Warehouse system. A critical question in design is whether we should integrate data mining systems with database systems. We can classify a data mining system according to the kind of databases mined. . systems, it is difficult for loose coupling to achieve high scalability and

The proposed methodology is evaluated by performing case study on real-world data set. Ein Data Warehouse ist häufig Ausgangsbasis für Data Mining. It may fetch data from a particular source (such as a file system), process data using some data mining algorithms, and then store the mining results in another file. Data warehouse refers to the process of compiling and organizing data into one common database, whereas data mining refers to the process of extracting useful data from the databases. As the information comes from various sources and in different formats, it can't be used directly for the data mining procedure because the data may not be complete and accurate. Unterschiede bei den Definitionen finden sich vor allem im generellen Zweck eines Data Warehouses sowie im Umfang und Umgang mit den Daten im Data Warehouse. Thus, this architecture represents a poor design choice. 2.Loose coupling: Loose coupling means
