DBMiner: A System for Data Mining in Relational Databases by Han J., Chiang J.Y., Chee S.

By Han J., Chiang J.Y., Chee S.

A knowledge mining approach, DBMiner, has been built for interactive mining of multiple-level wisdom in huge relational databases and knowledge warehouses. The process implements a large spectrum of knowledge mining services, together with characterization, comparability, organization, category, prediction, and clustering. by means of incorporating numerous attention-grabbing facts mining options, together with OLAP and attribute-oriented induction, statistical research, revolutionary deepening for mining multiple-level wisdom, and meta-rule guided mining, the procedure presents a ordinary, interactive facts mining atmosphere with sturdy functionality.

B. The denormalization process adds redundant data to an already normalized database to increase the performance of read queries. See chapter 11 for more information. 4. B. You should partition the table horizontally over several filegroups to boost performance. This solution will alleviate the contention problems while still maintaining one table for accessing the data. Partitioning a table is a new feature in SQL Server 2005. Adding more memory or moving the table to another disk will not relieve contention in the existing table.

The solution needs to be portable, updatable, easily maintained, and loosely coupled. Your budget allocates resources for rewriting the application and implementing the necessary hardware and software. Which of the following solutions should you consider? A. Scalable shared databases B. Peer-to-peer replication C. Service-Oriented Data Architecture D. Linked servers 13.

However, you have two distinct types of applications: those designed for managing data and those designed for administering systems. You can define these two types of applications as follows: Applications that use data access components to obtain data and store it in the database Administrative tools that use well-defined object models to enable you to administer your database system You require a data access system to create the link between your data and your application. All applications, regardless of the shape or size, require the same type of data access components.
