Data Mining, Southeast Asia Edition
Our ability to generate and collect data has been increasing rapidly. Not only are all of our business, scientific, and government transactions now computerized, but the widespread use of digital cameras, publication tools, and bar codes also generate data. On the collection side, scanned text and image platforms, satellite remote sensing systems, and the World Wide Web have flooded us with a tremendous amount of data. This explosive growth has generated an even more urgent need for new techniques and automated tools that can help us transform this data into useful information and knowledge.
Like the first edition, voted the most popular data mining book by KD Nuggets readers, this book explores concepts and techniques for the discovery of patterns hidden in large data sets, focusing on issues relating to their feasibility, usefulness, effectiveness, and scalability. However, since the publication of the first edition, great progress has been made in the development of new data mining methods, systems, and applications. This new edition substantially enhances the first edition, and new chapters have been added to address recent developments on mining complex types of data— including stream data, sequence data, graph structured data, social network data, and multi-relational data.

The entity-relationship data model is commonly used in the design of relational
databases, where a database schema consists of a set of entities and the
relationships between them. Such a data model is appropriate for on-line
The major difference between the snowflake and star schema models is that the
dimension tables of the snowflake model may be kept in normalized form to
reduce redundancies. Such a table is easy to maintain and saves storage space.
This kind of schema can be viewed as a collection of stars, and hence is called a
galaxy schema or a fact constellation. Fact constellation. A fact constellation
schema is shown in Figure 3.6. This schema specifies two fact tables, sales and ...
Examples for Defining Star, Snowflake, and Fact Constellation Schemas “How
can I define a multidimensional schema for my data?” Just as relational query
languages like SQL can be used to specify relational queries, a data mining
