Learn data mart with online courses and programs
What is a data mart?
A data mart is a simplified form of a data warehouse that serves a single business unit rather than the whole organization. It helps a particular team or department gain insights quickly without dealing with the complexity of a data warehouse. At the same time, it enables you to avoid the manual data consolidation process, which can be error-prone, time-consuming, and costly.Footnote 1
Data marts can help a department make informed decisions backed by data. For example, a marketing team can leverage data marts to analyze how customers react to their marketing campaigns. A data mart is designed based on the specific requirements of a department.Footnote 2

Data mart tutorial curriculum
Are you interested in learning about data marts? Online courses can help get you up to speed.
An introductory data mart course can cover the basics, such as the purpose of a data mart and its role in data management and decision-making processes. You may have a chance to study data mart architecture, including dimensional modeling, subsets of data, logical and physical components, and retrieval and analytical methods. By reviewing data mart examples, you may also be able to better understand the differences between data marts, data warehouses, and data lakes.
With a firm understanding of the basics, you can move on to an intermediate course. These courses can cover the elements of designing a data mart, including business requirements, data resource identification, data subset definition, and logical and physical data mart structure creation. Study the steps involved in the data mart construction process, such as creating the physical database and storage structures, creating schema objects like tables and indexes, and optimizing table setup. You may also learn how to translate database structures into business terms for user interaction.
For even more experienced learners, advanced level courses may explain how to make a data mart in SQL, along with the correct statements and queries for its creation and implementation. You can also potentially learn how to ensure the long-term viability of a data mart, including providing secure access, managing data growth, optimizing system performance, and ensuring data availability in the event of system failures.
