The process of understanding the complete effect of a particular change.

The installation of an increment of the data warehouse solution that is complete, tested, operational, and ready. An implementation includes all necessary software, hardware, documentation, and all required data.

A tool you use to collect business and system information during a business baseline interview. It consists of a pre-built set of questions organized by business function that are to be supplemented by the analyst with relevant company terms and other characteristics before use in driving the interview.

The defined scope of the portion of the data warehouse selected for implementation. Each increment satisfies elements of the total data warehouse solution.

The process of reconciling the designs, modules, database objects, and data access components within a given increment. This effort is addressed during the data warehouse architecture process.

A technique for producing all or part of a production system based on an outline definition. The technique involves iterations of a cycle of build, refine, and review so that the correct solution gradually emerges. This technique can be difficult to control, but nonetheless is very useful when properly used; also called quick build and interactive development.

A model that depicts access to key process and organization information for reporting and/or security purposes. Information Flow Model A model that visually depicts information flows in the business between business functions, business organizations and applications.

A person or software service that uses data to create information.

The identification and analysis of the needs for information required to satisfy a particular business driver.

A system for managing and processing information, usually computer-based. Also, a functional group within a business that manages the development and operations of the business’s information systems.

A method that aligns information technology priorities with business strategies and defines the approach to take to achieve those goals.

IBM's approach to data warehousing that supports the implementation of either functional, central or decentralized warehouses.

A deliverable is initial if it is intended to be updated later. An initial deliverable is usually preliminary and its content changeable by a later task when more information is known.

The first population of the production database installations using the data acquisition modules for extraction, transformation, and transportation.

The loading of an instance of an application system that is complete, tested, operational, and ready. An installation includes all necessary software, hardware (including terminals, networks, etc.) and documentation, and includes all required data.

Integrated operational data that have either been archived as individual data values or as full records from integrated operational data or are disparate operational or disparate historical data that have been transformed to the integrated data resource.

Subject-oriented, integrated, time-current, volatile collection of data that support an organization’s daily business activities. They are also know as operational data stores.

Used here in the broad sense to mean the transformation of disparate data into an integrated data resource.

A sequence of steps or set of procedures to verify the inter-operability of various system components.

A software routine that waits in the background and performs an action when a specified event occurs. For example, agents could transmit a summary file on the first day of the month or monitor incoming data and alert the user when certain transactions have arrived.

A linkage between systems which can be either automated (via software programs) or procedural (manual).

A data warehouse that tracks the analysis performed on evaluational data, adds or suggests the addition of permanent data subjects or queries based on frequency of use, and deletes or suggests the deletion of summary data subjects and queries based on a lack of use.

A situation or concern which requires a resolution. Some issues, if not addressed, could adversely impact the success of a project.

The application of a cyclic, evolutionary approach to the development of requirements definition, design, or construction using prototyping and iterative build techniques.
