Answer :
A data mart is a smaller-scale data collection than a data warehouse that caters to the requirements of a certain department or functional area of the company.
A data mart is a structure or access pattern used to retrieve client-facing data in data warehouse systems. Data marts are a subset of data warehouses and are often focused on one or more business units or teams.
Data marts contain information exclusive to one department, while data warehouses have a depth that spans the entire organisation. Depending on the deployment, each department or business unit may be regarded as the owner of its whole data mart, including all of the infrastructure, software, and data.
