What you'll learn in this 7-day crash course:

Day 1: Introduction to Databases and Relational Models

This day lays the groundwork. We'll explore what databases are, why they're crucial in today's data-driven world, and the advantages they offer over other data storage methods. We’ll delve into the relational model, understanding concepts like tables, rows, columns, primary keys, and foreign keys. The exercises will guide you through creating simple database schemas and identifying relationships between data entities. Downloadable resources include a sample relational database schema and SQL practice queries.

Day 2: SQL Fundamentals

Structured Query Language (SQL) is the cornerstone of database interaction. This day focuses on the fundamental SQL commands needed to interact with a relational database. We'll cover SELECT, INSERT, UPDATE, and DELETE statements, along with filtering data using WHERE clauses and sorting data with ORDER BY. Exercises will involve querying a sample database, manipulating data, and creating new data records. The downloadable materials include a SQL cheat sheet and a more complex database for practical exercises.

Day 3: Advanced SQL Techniques

Building upon Day 2, we’ll explore more advanced SQL techniques. Topics include JOIN operations (INNER, LEFT, RIGHT, FULL OUTER), aggregate functions (COUNT, SUM, AVG, MIN, MAX), grouping data with GROUP BY, and subqueries. Exercises will focus on complex data manipulation and retrieval using these advanced techniques. Downloadable content includes a series of challenging SQL queries to test your skills.

Day 4: Database Design Principles

Effective database design is critical for performance and maintainability. This day covers essential database design principles, including normalization (1NF, 2NF, 3NF), data integrity constraints, and indexing. You'll learn how to create efficient and scalable database schemas. Exercises involve designing database schemas for specific scenarios and identifying potential design flaws. The downloadable resource includes a database design template and normalization guidelines.

Day 5: Introduction to NoSQL Databases

While relational databases are prevalent, NoSQL databases are gaining significant traction. This day provides an introduction to NoSQL databases, highlighting their differences from relational databases and their respective use cases. We'll explore key NoSQL database types (document, key-value, graph, and column-family) and discuss their strengths and weaknesses. Downloadable content includes a comparison chart of different NoSQL databases.

Day 6: Database Administration Basics

This day focuses on the essential aspects of database administration. We'll cover concepts like backup and recovery, user management, security, and performance tuning. The exercises involve configuring basic database settings and troubleshooting common issues. The downloadable material contains a checklist for database administration best practices.

Day 7: Project and Further Learning

The final day involves a practical project that combines all the concepts learned throughout the week. You'll design, implement, and populate a database for a specific scenario. This project will solidify your understanding and build your confidence. We'll also provide resources for further learning and exploring specialized database technologies. The downloadable material includes a project brief and suggested resources for advanced learning.
