Chapter 1. Data Mining: Concepts and Techniques, Data Warehouse—Time Variant • The time horizon for the data warehouse is significantly longer than that of operational systems • Operational database: current value data • Data warehouse data: provide information from a historical perspective (e.g., past 5-10 years) • Every key structure in the data warehouse • Contains an element of time, explicitly or implicitly • But the key of operational data may or may not contain “time element” Data Mining: Concepts and Techniques, Data Warehouse—Nonvolatile • A physically separate store of data transformed from the operational environment • Operational update of data does not occur in the data warehouse environment • Does not require transaction processing, recovery, and concurrency control mechanisms • Requires only two operations in data accessing: • initial loading of data and access of data Data Mining: Concepts and Techniques, Data Warehouse vs. Heterogeneous DBMS • Traditional heterogeneous DB integration: A query driven approach • Build wrappers/mediators on top of heterogeneous databases • When a query is posed to a client site, a meta-dictionary is used to translate the query into queries appropriate for individual heterogeneous sites involved, and the results are integrated into a global answer set • Complex information filtering, compete for resources • Data warehouse: update-driven, high performance • Information from heterogeneous sources is integrated in advance and stored in warehouses for direct query and analysis Data Mining: Concepts and Techniques, Data Warehouse vs. • A multi-dimensional data model • Data warehouse architecture • Data warehouse implementation • From data warehousing to data mining • Summary Data Mining: Concepts and Techniques, Summary: Data Warehouse and OLAP Technology • Why data warehousing? data-mining-concepts-and-techniques-3rd-edition 3/4 Downloaded from hsm1.signority.com on December 19, 2020 by guest Contents in PDF.

Therefore, our solution • High performance for both systems • DBMS— tuned for OLTP: access methods, indexing, concurrency control, recovery • Warehouse—tuned for OLAP: complex OLAP queries, multidimensional view, consolidation • Different functions and different data: • missing data: Decision support requires historical data which operational DBs do not typically maintain • data consolidation: DS requires consolidation (aggregation, summarization) of data from heterogeneous sources • data quality: different sources typically use inconsistent data representations, codes and formats which have to be reconciled • Note: There are more and more systems which perform OLAP analysis directly on relational databases Data Mining: Concepts and Techniques, From Tables and Spreadsheets to Data Cubes • A data warehouse is based on a multidimensional data model which views data in the form of a data cube • A data cube, such as sales, allows data to be modeled and viewed in multiple dimensions • Dimension tables, such as item (item_name, brand, type), or time(day, week, month, quarter, year) • Fact table contains measures (such as dollars_sold) and keys to each of the related dimension tables • In data warehousing literature, an n-D base cube is called a base cuboid.
