## Course Details
- **Duration:** ~4h
- **Level:** Beginner
- **Instructor:** Lis Sulmont
- **Students:** ~19,440,000 learners
- **Subjects:** SQL, Data Engineering, Data Science and Analytics
- **Content brand:** DataCamp
- **Practice:** Hands-on practice included
- **CPE credits:** 3
- **Prerequisites:** Introduction to Relational Databases in SQL
## Learning Outcomes
- Define core database processing approaches, including OLTP and OLAP, and implement each in appropriate operational or analytical scenarios
- Differentiate normalized and denormalized schema designs by identifying first through third normal forms, star versus snowflake schemas, and their impacts on read and write performance
- Distinguish between structured, semi-structured, and unstructured data storage options such as traditional relational databases, data warehouses, and data lakes
- Evaluate database management strategies to satisfy scalability, consistency, and governance requirements
- Implement database views and materialized views to optimize security, usability, and refresh latency
## Traditional Course Outline
1. Processing, Storing, and Organizing Data - Start your journey into database design by learning about the two approaches to data processing, OLTP and OLAP. In this first chapter, you'll also get familiar with the different forms data can be stored in and learn the basics of data modeling.
2. Database Schemas and Normalization - In this chapter, you will take your data modeling skills to the next level. You'll learn to implement star and snowflake schemas, recognize the importance of normalization and see how to normalize databases to different extents.
3. Database Views - Get ready to work with views! In this chapter, you will learn how to create and query views. On top of that, you'll master more advanced capabilities to manage them and end by identifying the difference between materialized and non-materialized views.
4. Database Management - This final chapter ends with some database management-related topics. You will learn how to grant database access based on user roles, how to partition tables into smaller pieces, what to keep in mind when integrating data, and which DBMS fits your business needs best.
