Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning , statistics , and database systems. The term "data mining" is a misnomer , because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction mining of data itself. The book Data mining: Practical machine learning tools and techniques with Java [8] which covers mostly machine learning material was originally to be named just Practical machine learning , and the term data mining was only added for marketing reasons.

The classical multidimensional models were meant to analyze conventional data numerical and categorical. However, they fail to handle data complexity, which is expressed by the multiplicity of data sources, the heterogeneity of formats, the diversity of structures, etc. To this end, new multidimensional models have been proposed for OLAP purposes. Nevertheless, data complexity is partially covered in these models, which may cause a lack in decision making. In our previous work, we proposed to integrate data complexity within a complex object-based multidimensional model.

International Journal of Current Research , , vol. The 21st Century is witnessing a massive flow of information in library. Today, one of the biggest challenges that libraries face is the enormous amount of data generation and to use this data to improve the quality of managerial decisions. Data mining techniques are analytical tools that can be used to extract meaningful knowledge from large data sets. To do this extraction, data mining combines artificial intelligence, statistical analysis and database management systems to attempt to pull knowledge form stored data. The present paper addresses the applications of data mining in library in an effective and efficient manner. Advantages and Disadvantages of Data Mining.

There are more than one billion documents on the Web, with the count continually rising at a pace of over one million new documents per day. As information increases, the motivation and interest in data warehousing and mining research and practice remains high in organizational interest.

Data mining

Data stored in a data warehouse DW are retrieved and analyzed by complex analytical applications, often expressed by means of star queries. Such queries often scan huge volumes of data and are computationally complex. For this reason, an acceptable or good DW performance is one of the important features that must be guaranteed for DW users. Good DW performance can be achieved in multiple components of a DW architecture, starting from hardware e. In this chapter we aim at presenting only a narrow aspect of the aforementioned technologies. We discuss three types of data structures, namely indexes bitmap, join, and bitmap join , materialized views, and partitioned tables. Unable to display preview.

Если там и произошло что-то неприятное, то дело не в вирусах. Молчание. - Мидж. Ты меня слышишь. От ее слов повеяло ледяным холодом: - Джабба, я выполняю свои должностные обязанности.

Как только он оказался там, его сразу же увлек за собой поток молодых людей. - А ну с дороги, пидор! - Некое существо с прической, больше всего напоминающей подушечку для иголок, прошествовало мимо, толкнув Беккера в бок. - Хорошенький! - крикнул еще один, сильно дернув его за галстук. - Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов. Темнота коридора перетекла в просторное цементное помещение, пропитанное запахом пота и алкоголя, и Беккеру открылась абсолютно сюрреалистическая картина: в глубокой пещере двигались, слившись в сплошную массу, сотни человеческих тел. Они наклонялись и распрямлялись, прижав руки к бокам, а их головы при этом раскачивались, как безжизненные шары, едва прикрепленные к негнущимся спинам. Какие-то безумцы ныряли со сцены в это людское море, и его волны швыряли их вперед и назад, как волейбольные мячи на пляже.
