Data marts can be thought of as smaller data warehouses focused on specific user groups or goals, such as sales, marketing or finance. They contain
data relevant to specific business processes and analyses and are built to provide quick access to the data needed to make decisions.

Unlike a data warehouse, which is often designed to support a broad set of data for the entire organization, a data mart is focused on the needs of a specific group of users within the organization.

A data mart is usually designed to provide quick and easy access to specific data, using tools such as reports, dashboards and analysis tools. It can also be optimized to perform specific types of analysis, such as trend analysis, predictive analysis or segmentation analysis.

The goal of creating a data mart is to improve the efficiency and effectiveness of decision-making within an organization by providing quick and easy access to the data needed to make decisions.
