Free Online Course from Coursera: Database Management Essentials

Coursera offers a free online course in Database Management Essentials. This course 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.

Course Description:-

• 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.

• This course is designed 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.

Syllabus:-

• Week 1

  • 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 last lesson of module 1.

    • It’s recommended that you try to install the DBMS software this week before assignments begin in week 2.

  • Introduction to Databases and DBMSs

    • The course will launch into an exploration of databases and database technology and their impact on organizations in Module 2.

    • The course 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 will ensure that you have the required background and context, which is critical for success in the later modules that emphasize details and hands-on skills.

• Week 2

  • Relational Data Model and the CREATE TABLE Statement

    • Now that you have the informational 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 Oracle, MySQL, or PostgreSQL, creating tables using the SQL CREATE TABLE statement and populating your tables using given SQL INSERT statements.

• Week 3:

  • 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, you can understand 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.

  • 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.

• Week 4

  • Notation for Entity Relationship Diagrams

    • Module 6 represents another shift in your learning. In previous modules, you’ve created and populated tables and developed query formulation skills using the SQL SELECT statement. Now you’ll start to develop skills that allow you to create a database design to support business requirements.

    • You’ll learn basic notation used in entity relationship diagrams (ERDs), a graphical notation for data modeling.

    • You will create simple ERDs using basic diagram symbols and relationship variations to start developing your data modeling skills.
