Introduction to Data Mining (Second Edition)

A data warehouse is a databas e designed to enable business intelligence activities: it exists to help users understand and enhance their organization's performance. It is designed for query and analysis rather than for transaction processing, and usually contains historical data derived from transaction data, but can include data from other sources. Data warehouses separate analysis workload from transaction workload and enable an organization to consolidate data from several sources. This helps in:. In addition to a relational database, a data warehouse environment can include an extraction, transportation, transformation, and loading ETL solution, statistical analysis, reporting, data mining capabilities, client analysis tools, and other applications that manage the process of gathering data, transforming it into useful, actionable information, and delivering it to business users.

Avoiding False Discoveries: A completely new addition in the second edition is a chapter on how to avoid false discoveries and produce valid results, which is novel among other contemporary textbooks on data mining. It supplements the discussions in the other chapters with a discussion of the statistical concepts statistical significance, p-values, false discovery rate, permutation testing, etc. This chapter addresses the increasing concern over the validity and reproducibility of results obtained from data analysis. The addition of this chapter is a recognition of the importance of this topic and an acknowledgment that a deeper understanding of this area is needed for those analyzing data. Classification: Some of the most significant improvements in the text have been in the two chapters on classification. The introductory chapter uses the decision tree classifier for illustration, but the discussion on many topics—those that apply across all classification approaches—has been greatly expanded and clarified, including topics such as overfitting, underfitting, the impact of training size, model complexity, model selection, and common pitfalls in model evaluation.

The present book's subject is multidimensional data models and data modeling concepts as they are applied in real data warehouses. The book aims to present the most important concepts within this subject in a precise and understandable manner. The book's coverage of fundamental concepts includes data cubes and their elements, such as dimensions, facts, and measures and their representation in a relational setting; it includes architecture-related concepts; and it includes the querying of multidimensional databases. The book also covers advanced multidimensional concepts that are considered to be particularly important. This coverage includes advanced dimension-related concepts such as slowly changing dimensions, degenerate and junk dimensions, outriggers, parent-child hierarchies, and unbalanced, non-covering, and non-strict hierarchies. The book offers a principled overview of key implementation techniques that are particularly important to multidimensional databases, including materialized views, bitmap indices, join indices, and star join processing.

 Это н-не… - заикаясь, произнесла она вслух, - невероятно. И, словно возражая ей, в ее мозгу эхом прозвучали слова Хейла, сказанные чуть раньше: Танкадо не раз мне писал… Стратмор сильно рисковал, взяв меня в АНБ… Рано или поздно я отсюда слиняю. Но Сьюзан физически не могла примириться с тем, что увидела.

Он стоит десять раз по двадцать миллионов. - Увы, - сказал Нуматака, которому уже наскучило играть, - мы оба знаем, что Танкадо этого так не оставит. Подумайте о юридических последствиях.

При росте более ста восьмидесяти сантиметров он передвигался по корту куда быстрее университетских коллег. Разгромив очередного партнера, он шел охладиться к фонтанчику с питьевой водой и опускал в него голову. Затем, с еще мокрыми волосами, угощал поверженного соперника орешками и соком. Как у всех молодых профессоров, университетское жалованье Дэвида было довольно скромным.
