Databases are used for creating and storing virtually any type of data. Data drives business in the twenty-first century, and IT professionals interested in mastering data analytics must understand the key concepts surrounding databases and their uses in almost every facet of business. In this course, you will discover database concepts, beginning with challenges associated with databases, self-driving databases, data warehouses, data marts, and data lakes and lakehouses. Then you will explore the concepts of Online Transactional Processing (OLTP) and Online Analytical Processing (OLAP). You will learn about database schemas and look closely at star and snowflake schemas, which are common in data warehouses. Finally, you will explore slowly changing dimensions that shape the methods analysts use to keep historical and current data. This course can be used to prepare for the DA0-001: CompTIA Data+ exam.
