Relational Database Implementation and Applications

In Module 1, 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.

Module 2 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().

In Module 3, you'll learn how to develop database applications using versatile programming languages such as Java, Python, or C++. You'll discover how to establish connections to databases, perform essential CRUD operations, and write code that supports SQL features like triggers, functions, and stored procedures used to facilitate complex queries in relational databases.

Module 4 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.

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.

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.

This module contains the summative course assessment that has been designed to evaluate your understanding of the course material and assess your ability to apply the knowledge you have acquired throughout the course.
