Welcome to Relational Database Implementation and Applications! In Module 1 of this course, you'll delve into the fundamental aspects of building relational databases. You'll learn about implementing indexes, views, triggers, functions, and stored procedures in relational databases. We'll highlight the significance of these elements in databases and how they enhance query performance. You'll explore the creation of both simple and complex views, understanding how they offer data abstraction benefits and the versatility of managing data through views. Additionally, you'll gain experience in creating and optimizing database operations using user-defined functions, triggers, and stored procedures in SQL, thus acquiring comprehensive knowledge of accurate business logic implementation and performance optimization techniques.

Module 2 of this course offers an immersive exploration of the powerful world of SQL window functions and OLAP (Online Analytical Processing) concepts. You will learn about the definition and benefits of window functions, gaining proficiency in advanced applications such as RANK(), DENSE_RANK(), LEAD(), LAG(), NTILE(n), PERCENT_RANK(), and CUME_DIST(). Additionally, you'll develop the skills to control window function behavior using PARTITION BY and ORDER BY clauses, define custom window frames with RANGE and ROWS clauses, and design, query, and analyze OLAP datasets using ROLL-UP and DRILL-DOWN levels of aggregation.

Module 4 of this course provides an in-depth understanding of indexing within database systems. You'll define indexing and grasp its critical importance. Through comprehensive exploration, you'll differentiate between various types of indexes, including ordered and hash indexes, primary and secondary indexes, as well as multi-level and single-level indexes. Additionally, you'll delve into the structure of B+-trees, including nodes and leaves, and learn how these structures maintain balance, supporting efficient search operations. You'll also gain insight into B+-tree insertion and deletion operations.

In Module 5, you will enter into the world of database transactions and their critical role in ensuring data consistency and integrity. You will gain a comprehensive understanding of the four ACID properties (Atomicity, Consistency, Isolation, Durability) and their significance in maintaining the reliability of transactions. Additionally, you'll explore techniques for managing concurrent access to data, including discussions on COMMIT and ROLLBACK behaviors, serial and serializable schedules, and conflict serializability tests using graph-based techniques. This module will also cover concepts like equivalent serial schedules, recoverability, and cascade-less schedules, empowering you to design and manage complex database systems with confidence and precision.

Module 6 focuses on concurrency control in database management systems. You'll define concurrency control and understand its significance in maintaining data integrity while delving into the principles of lock-based concurrency control. This module will cover key concepts such as shared and exclusive lock types, lock modes, lock compatibility, and introduce the two-phase locking protocol with its guarantees. Additionally, you'll gain insights into how transactions acquire and release locks within this protocol, and you'll explore the concept of deadlocks and their underlying causes, equipping you with essential knowledge to manage concurrent access effectively and prevent data integrity issues in database systems.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
