Data Store is a repository for persistently storing and managing collections of data, which can include databases, data warehouses, or other types of data systems. Coursera's Data Store catalogue teaches you the foundational principles and advanced techniques of managing and working with different types of data stores. You'll learn about data modeling, database design, data warehousing, data querying, and data security. You'll also gain knowledge on how to work with both SQL and NoSQL databases, understand the concepts of data normalization and denormalization, and learn to effectively use data indexing and transactions. This skill is essential for roles such as data engineer, database administrator, backend developer, and data scientist.
