Course Description

Welcome to the "Database Systems with SQL" course, your gateway to mastering the core principles and practices of database systems. Whether you're an aspiring database administrator, developer, or someone interested in understanding the intricacies of databases, this comprehensive course offers a rich blend of theoretical knowledge and practical skills to help you succeed.

This immersive course, which spans 4 hours and 32 minutes, delves into a wide array of topics under the Information Technology category, with a specific focus on Databases. Designed to provide a thorough understanding of both relational and NoSQL databases, the curriculum begins with foundational concepts and gradually progresses to more advanced subjects.

We start by unraveling the basics with an introduction to data, followed by a thorough overview of databases and database management systems (DBMS). You’ll learn about the critical roles users play in a database environment and gain insights into the nuances of database transactions, ensuring you grasp how to manage data integrity and concurrency.

Understanding the architecture of database systems is crucial, and this course provides a clear comparison between relational and NoSQL databases. You'll explore SQL, the structured query language, and embark on the database design process, covering all phases from analysis to physical design.

The practical part of the course starts with the installation of MySQL Workbench and initiation of a database server. You will get hands-on experience with database models, relational models, tables, columns, rows, various data types, and the crucial concepts of primary and foreign keys. Moreover, you'll delve into SQL commands, constraints, and the powerful SELECT statement to retrieve, manipulate, and aggregate data efficiently.

One essential aspect of databases is their adherence to normalization principles. This course thoroughly explains the First, Second, and Third Normal Form (1NF, 2NF, 3NF), along with Boyce-Codd Normal Form (BCNF) and denormalization techniques, ensuring you can maintain data integrity and optimize performance.

The course also emphasizes advanced query techniques, including inner and outer joins, subqueries, and query optimization. You'll be equipped to construct entity-relationship (ER) diagrams and understand different dependency relationships, vital for effective database design.

As we move further, you'll be introduced to SQL execution with statements for creating, updating, and deleting databases and tables. Learn about table constraints, transactions with commit and rollback, and the significant ACID properties that ensure reliable database transactions.

The course doesn't stop at theoretical aspects but extends to practical programming with databases. You'll explore embedded SQL programming, procedural SQL with PL/SQL, and connecting databases with popular programming languages using MySQL APIs. Hands-on exercises in Python and Java database programming will solidify your understanding, enabling you to implement stored procedures and manage queries effectively.

In an era where data is paramount, understanding Big Data and NoSQL databases becomes indispensable. This course provides an overview of various NoSQL databases, including key-value pairs, wide-column stores, document databases, and graph databases, each tailored to specific data requirements.

To sum up, "Database Systems with SQL" is a detailed and practical course that empowers you with essential database skills needed in today's technology-driven world.
