A subset of the data resource, usually oriented to a specific purpose or major data subject, that may be distributed to support business needs. The concept of a data mart can apply to any data whether they are operational data, evaluational data, spatial data, or metadata.
Usually sponsored at the department level and developed with a specific issue or subject in mind, a Data Mart is a data warehouse with a focused objective. The scope of data in a data mart is limited to data supporting the target objective. In this sense, the data mart is more structured than a general-purpose data warehouse. Data mart's are now generally recognized as the most cost-effective approach to data warehousing.
A small, single-subject warehouse used by individual departments or groups of users.
A data mart serves purposes similar to a data warehouse (see definition below) but is generally organized around a subject area. Often the subject areas are functional, such as student information, employee information, financial information, etc. A data mart may also be organized around an operational area, such as executives, managers, students, etc.
Data marts have the same definition as the data warehouse (see below), but data marts have a more limited audience and/or data content.
A subset of a data warehouse. Where data warehouses are designed to support many requirements for multiple business needs, data marts are designed to support specific requirements for specific decision support applications (i.e., particular business needs). Data marts are typically considered a solution for distributed users who want exclusive control of the information required for their business need.
A set of data designed and constructed for decision support purposes reflecting the design principles of a data warehouse provided to serve the needs of a homogenous user group. ()
A specialized repository tailored to support a specific business function
A database, or collection of databases, designed to help managers make strategic decisions about their business. Whereas a data warehouse combines databases across an entire enterprise, data marts are usually smaller and focus on a particular subject or department.
The gathering of extensive data - especially on customers and sales - and complex multi-dimensional queries on the data. Depending on the type of data storage, one distinguishes between Data Marts and Data Warehouses. Data Mining refers to the analysis of data records.
An implementation of an analytics application serving a single department, subject area, or limited part of the organization. Usually refers to a physical platform on which summarized data is stored for decision support. Data marts are commonly used for specific analysis purposes by a single organization or user group.

A type of data warehouse designed to meet the needs of a specific group of users such as a single department or part of an organization. Typically a data mart focuses on a single subject area such as sales data. Data marts may or may not be designed to fit into a broader enterprise data warehouse design.
A repository of data, often a scale-down data warehouse, usually tailored to the needs of a specific group within an organization
A database with similar characteristics to a data warehouse, only smaller and designed for a specific division or department instead of the business as a whole. Several data marts can be combined into a data warehouse using conformed dimensions.
A data mart is similar to a data warehouse, smaller in size, designed for a specific purpose. The contents of a data mart may or may not come from a data warehouse. A data warehouse tends to be larger and all encompassing, while a data mart will meet more immediate tactical needs and is tailored for a smaller target user base.

A data warehouse-like approach limited to a single function or purpose, such as promotion planning.
A subset of information relevant to a group of users which is transferred to a separate departmental server. The database involved can be relational, although a multi-dimensional OLAP server is often more appropriate. A range of end-user tools can be used to access the data in a data mart.

A data mart (DM) is a specialized version of a data warehouse (DW). Like data warehouses, data marts contain a snapshot of operational data that helps business people to strategize based on analyses of past trends and experiences. The key difference is that the creation of a data mart is predicated on a specific, predefined need for a certain grouping and configuration of select data.
