Description
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.
What you will learn
Course Introduction
Module 1 provides the context for Database Management Essentials. When you’re done, you’ll understand the objectives for the course and know what topics and assignments to expect. Keeping these course objectives in mind will help you succeed throughout the course! You should read about the database software requirements in the second lesson of module 1. I recommend that you try to install the DBMS software this week before assignments begin in module 3.
Introduction to Databases and DBMSs
You will launch into an exploration of databases and database technology and their impact on organizations in Module 2. You will investigate database characteristics, database technology features, including non-procedural access, two key processing environments, and an evolution of the database software industry. This short informational module ensures a common background and context, important for success in later modules that emphasize details and hands-on skills.
Relational Data Model and the CREATE TABLE Statement
Now that you have the context for database features and environments, you’ll start building! In this module, you’ll learn relational data model terminology, integrity rules, and the CREATE TABLE statement. You’ll apply what you’ve learned in practice and graded problems using a database management system (DBMS), either the Oracle Cloud database server with the SQL Developer client or the PostgreSQL database server with the pgAdmin client. You will use the SQL CREATE TABLE statement and populate your tables using given SQL INSERT statements. 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.
Basic Query Formulation with SQL
This module is all about acquiring query formulation skills. Now that you know the relational data model and have basic skills with the CREATE TABLE statement, we can cover basic syntax of the SQL SELECT statement and the join operator for combining tables. SELECT statement examples are presented for single table conditions, join operations, and grouping operations. You’ll practice writing simple SELECT statements using the tables that you created in the assignment for module 3. 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.
Extended Query Formulation with SQL
Now that you can identify and use the SELECT statement and the join operator, you’ll extend your problem solving skills in this module so you can gain confidence on more complex queries. You will work on retrieval problems with multiple tables and grouping. In addition, you’ll learn to use the UNION operator in the SQL SELECT statement and write SQL modification statements. 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.
