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.

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.

Foire Aux Questions
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.
