A data mart is a subset of an organization's data warehouse that is specifically designed to serve the needs of a particular department or business unit. It is a smaller, more specialized version of a data warehouse that contains a focused collection of data to support the analytical and reporting requirements of a specific group within an organization.
In essence, a data mart is a repository of data that is organized and structured in a way that is most useful to a targeted group of users. It is designed to provide easy and quick access to relevant data, allowing users to efficiently retrieve and analyze the information they need to make informed decisions.
Data marts are typically created to address the specific needs and goals of a particular department, such as sales, marketing, finance, or human resources. They are often used to support specific business functions, such as sales analysis, customer relationship management, or inventory management.
Data marts are usually created by extracting data from the larger data warehouse and transforming and reorganizing it to suit the specific needs of the user group. This process of data extraction, transformation, and loading is known as ETL.
Overall, data marts provide a way to efficiently store, retrieve, and analyze relevant data for a specific group of users within an organization, enabling them to gain valuable insights and support decision-making processes.
The word "data mart" is a combination of two separate terms: "data" and "mart".
1. Data: The term "data" comes from the Latin word "datum", which means "something given" or "a fact or piece of information". It has been in use since the 17th century to refer to information or facts that are collected, stored, and analyzed.
2. Mart: The term "mart" is a shortened form of the word "market", which is derived from the Old English word "mearcet". It refers to a place where goods are bought and sold. The term "mart" has been used since the 15th century to describe a commercial center or marketplace.
Combining these two terms, "data mart" is a phrase coined to describe a specific kind of specialized database or subset of a data warehouse that provides data for analysis and decision-making in a specific business department or function.
