The document discusses capacity planning for a data warehouse environment. It notes that capacity planning is important given the large volumes of data and processing in a data warehouse. It describes factors that make capacity planning unique for a data warehouse, such as variable workloads and larger data volumes than operational systems. The document provides guidance on estimating disk storage needs, classifying and estimating processing workloads, creating workload profiles, identifying peak capacity needs, and selecting hardware capacity to meet needs.
Data warehousing involves assembling and managing data from various sources to provide an integrated view of enterprise information. A data warehouse contains consolidated, historical data used to support management decision making. It differs from operational databases by containing aggregated, non-volatile data optimized for queries rather than updates. The extract, transform, load (ETL) process migrates data from source systems to the warehouse, transforming it as needed. Process managers oversee loading, maintaining, and querying the warehouse data.
Search engines allow users to search the vast collection of documents on the web. They consist of crawlers that fetch web pages, indexers that analyze page content and links, and interfaces that allow users to enter queries. Crawlers add pages to an index by following links, and indexers create inverted indexes to map words to pages. When a query is searched, results are retrieved from the index and ranked based on relevance. PageRank is a key algorithm that ranks pages higher that receive more links from other highly ranked pages. While it effectively searches the large, diverse and dynamic web, search poses challenges in understanding ambiguous queries over an evolving collection.
Web mining involves applying data mining techniques to discover useful information from web data. There are three types of web mining: web content mining analyzes data within web pages, web structure mining examines the hyperlink structure between pages, and web usage mining involves analyzing server logs to discover patterns in user behavior and interactions with websites. Web mining has applications in website design, web traffic analysis, e-commerce personalization, and security/crime investigation.
Information privacy and data mining
The document discusses information privacy and data mining. It defines information privacy as an individual's ability to control how information about them is shared. It outlines the basic OECD principles for protecting information privacy, including collection limitation, purpose specification, use limitation, security safeguards, and accountability. It describes common uses of data mining like fraud prevention but also potential misuses that can violate privacy. The document also discusses the primary aims of data mining applications and five pitfalls like unintentional mistakes, intentional abuse, and mission creep.
The document discusses cluster analysis, which groups data objects into clusters so that objects within a cluster are similar but dissimilar to objects in other clusters. It describes key characteristics of clustering, including that it is unsupervised learning and the clusters are determined algorithmically rather than by humans. Various clustering algorithms are covered, including partitioning, hierarchical, density-based, and grid-based methods. Applications of clustering discussed include business intelligence, image recognition, web search, outlier detection, and biology. Requirements for effective clustering in data mining are also outlined.
Association analysis is a technique used to uncover relationships between items in transactional data. It involves finding frequent itemsets whose occurrence exceeds a minimum support threshold, and then generating association rules from these itemsets that satisfy minimum confidence. The Apriori algorithm is commonly used for this task, as it leverages the Apriori property to prune the search space - if an itemset is infrequent, its supersets cannot be frequent. It performs multiple database scans to iteratively grow frequent itemsets and extract high confidence rules.
