According to William Inmon, widely considered the father of the modern data warehouse, a Data Warehouse is a "Subject-Oriented, Integrated, Time-Variant, Nonvolatile collection of data in support of decision making". Data Warehouses tend to have these distinguishing features: (1) Use a subject oriented dimensional data model; (2) Contain publishable data from potentially multiple sources and; (3) Contain integrated reporting tools.
large collection of data from business operations, as well as from other sources, that is used for extensive analysis.
A collection of databases combined with a flexible data extraction system.
The most widely recognized definition of a data warehouse is, “subject-oriented, integrated, time variant, non-volatile collection of data in support of management's decision-making process.” (Inmon, 1992). Subject-oriented means the data warehouse focuses on the high-level entities of the business, such as students, courses, accounts, and employees. This is in contrast to operational systems, which deal with processes such as student registration or payment of an invoice. Integrated means the data are stored in consistent formats (e.g., consistent naming conventions, domain constraints, physical attributes, and measurements). Time variant means the data are associated with a point in time (e.g., semester, fiscal year, or pay period). Finally, non-volatile means the data do not change once they are entered into the warehouse. Data warehouses are large collections of uniquely organized data that are primarily used to support analytical processes. They can contain highly aggregated as well as finely detailed data that is designed to assist in the decision-making tasks of senior management and operational staff alike.
A warehouse is a subject-oriented, integrated, time-variant and non-volatile collection of data in support of management's decision making process (as defined by Bill Inmon).
Integrates separate databases within a health care system for the interchange of data and reports to allow the management information system (MIS) system to handle data from several sources as if from one source. (See Clinical Data Repository)
General definition. UCLA's Data Warehouse is called the QDB.
The department or entity charged with collecting organization-wide data, verifying its accuracy, and analyzing, managing, and distributing it throughout the organization. In organizations without a data warehouse, each department may collect, analyze, manage, and distribute the data it needs for its operations.

A data warehouse is a collection of data designed to support decision making and analytical processing. Data warehouses contain a wide variety of data, usually from multiple data sources, presenting a comprehensive view of a particular business environment. Due to the nature of the data stored in a data warehouse, the size of the data warehouse is usually very large, so it requires special design and planning.

It can be used to support customer segmentation, profitability analysis, campaign management, oneâ€‘toâ€‘one marketing, data mining, etc.
A relational database that is designed for query and analysis rather than transaction processing. A data warehouse usually contains historical data that is derived from transaction data, but it can include data from other sources. It separates analysis workload from transaction workload and enables a business to consolidate data from several sources. In addition to a relational database, a data warehouse environment often consists of an ETL solution, an OLAP engine, client analysis tools, and other applications that manage the process of gathering data and delivering it to business users. See Also: ETL and online analytical processing (OLAP)
The Data Warehouse is a central repository of data that provides the MIT community with integrated, up-to-date data from various administrative systems. Using a reporting tool called BrioQuery, you can download the information from the database into a report format. Many standard data warehouse reports are available, or you can create reports of your own.

An integrated repository of data from multiple, possibly heterogeneous data sources, presented with consistent and coherent semantics. Warehouses usually contain summary information represented on a centralized storage facility.
A subject-oriented non-volatile collection of data used to support strategic decision making. The warehouse is the central point of data integration for business intelligence. It is the source of data for data marts within an enterprise and delivers a common view of enterprise data.
Data Warehouse ¸ê®ÆÜÀx¨t
A database, frequently very large, that can access all of a company's information. While the warehouse can be distributed over several computers and may contain several databases and information from numerous sources in a variety of formats, it should be accessible through a server. Thus, access to the warehouse is transparent to the user, who can use simple commands to retrieve and analyze all the information. The data warehouse also contains data about how the warehouse is organized, where the information can be found, and any connections between data. Frequently used for decision support within an organization, the data warehouse also allows the organization to organize its data, coordinate updates, and see relationships between information gathered from different parts of the organization.
An enterprise structured repository of subject-oriented, time-variant, historical data used for information retrieval and decision support. The data warehouse stores atomic and summary data. The data warehouse is the source data stored in the data marts.
A database built to support information access. Typically a data warehouse is fed from one or more transaction databases. The data needs to be cleaned and restructured to support queries, summaries, and analyses.
A data warehouse is one or more databases designed to support management, analysis, reporting and decision making in an organization. Data from the operational systems (such as Banner) are migrated to the data warehouse so that queries can be performed without disturbing the performance or the stability of the operational systems. The traditional features of a data warehouse are: subject-oriented, integrated across subject areas and time-oriented, i.e., there is a historical perspective to the data. A data warehouse generally contains both detailed data and may also contain summarized data. What is included in a data warehouse environment varies widely but is generally acknowledged to be the database(s), documentation about the data (metadata), a delivery/access method and a commitment to extract, transform and load (ETL) data from multiple source systems. (Adapted from http://www.pcmag.com/encyclopedia_term and Bill Inmon, 1996) ()

A collection of databases combining information from different parts of an organization, generally used in conjunction with data mining techniques. A large retailer's data warehouse, for example, may contain information about customer purchases, supplier deliveries, transport vehicle schedules and new products.
Databases that typically have more information in them than repositories, bringing together clinical, financial and demographic information. Data warehouses are typically used retrospectively to conduct research through the use of on-line analytical processing tools.
Data mining and data warehousing go hand in hand. Before you can effectively mine information, you have to put it all in one place - at least temporarily. Data warehousing involves integrating information from different systems, functions, and locations across an enterprise into a central database to allow more accurate analysis of customer needs, buying patterns, and profitability and improved decision making and marketing.
The Warehouse allows faculty, staff, experienced system developers, and institutional researchers to perform direct queries on administrative University data.
A generic term for a system for storing, retrieving and managing large amounts of any type of data. Data warehouse software often includes sophisticated compression and hashing techniques as well as specially designed databases for fast searches.
The critical factor leading to the use of a data warehouse is that a data analyst can perform complex queries and analysis (such as data mining) on the information without slowing down the operational systems.
