Subject matter

The Storing and Retrieving of Data course unit covers an introduction to SQL and NO SQL Databases, ETL operations, and Data Warehousing. Students will learn the advantages and disadvantages of each solution (SQL vs NO SQL) in order to be better to decide which solution is best for their needs. Students will learn the differences of developing databases for Transaction Oriented (OLTP) or Analytical (OLAP) operations. Finally, the course will cover the main concepts and definitions of Data Warehousing, the role of ETL operations in retrieving data from OLTP systems, the main differences among the different Data Warehousing architectures, and the basic Data Warehousing operations.
