Advanced query formulation can provide an edge in the workplace helping learners reach expert status with more value to an organization. Due to the advanced material, Module 12 provides Lesson 6 as honors with problems, quiz, assignment, and self evaluation. Module 12 covers four somewhat independent topics (outer joins, nested queries, membership exceptions, and containment exceptions) so learners can study these topics separately. These specialized problem areas, more difficult than combining tables with joins, provide important value to organizations when occurring in practice. To aid learners, Module 12 provides unique pedagogy with two problem-solving aids, text patterns to recognize elements of in problem statements and statement patterns to write template SELECT statements as an initial step to a complete SELECT statement. Lesson 5 provides a convenient summary of the text and statement patterns to provide learners a platform for the practice problems and assignment. The concept quiz provides an assessment of your understanding of the video lessons and associated notes. You should complete the concept quiz before starting practice problems and the graded assignment to ensure your conceptual understanding of the material.
Database Management Essentials provides the foundation you need for a career in database development, data warehousing, or business intelligence, as well as for the entire Data Warehousing for Business Intelligence specialization. In this course, you will create relational databases, write SQL statements to extract information to satisfy business reporting requests, create entity relationship diagrams (ERDs) to design databases, and analyze table designs for excessive redundancy. As you develop these skills, you will use either Oracle, MySQL, or PostgreSQL to execute SQL statements and a database diagramming tool such as the ER Assistant or Visual Paradigm to create ERDs. We’ve designed this course to ensure a common foundation for specialization learners. Everyone taking the course can jump right in with writing SQL statements in Oracle, MySQL, or PostgreSQL.
