Database Basics and Scalability: Covering relational design, NoSQL strategies, caching solutions, and time series data
What you'll learn​

Choose between SQL, NoSQL, NewSQL, and specialized databases by understanding their distinct use cases and architectural trade-offs
Master relational databases through schema design, ACID compliance, and SQL querying for traditional enterprise applications
Understand key-value stores for high-speed caching and session management, with strategies for handling data relationships
Learn how applications with document databases like MongoDB, leverage flexible schemas and complex document queries
Learn about columnar databases like Cassandra for distributed data processing and analytics across multiple database instances
Scale applications horizontally using database sharding, replication, and distributed transaction management
Harness time series databases for IoT sensors, market data, and application monitoring with efficient data aggregation
Design systems using NewSQL databases that combine ACID compliance with horizontal scaling for global applications
Integrate Java applications with databases using JDBC and ORM frameworks while optimizing for performance
Understand graph databases for complex relationship mapping in social networks and recommendation systems
Requirements
Basic knowledge of at least one programming language
Familiarity with common system design concepts (client-server interactions, APIs)
Description
Are you preparing for an interview or working on a codebase and need a rock-solid foundation in database technologies? Look no further. Database Essentials for Backend Engineers is a comprehensive dive into the world of data storage, designed to equip you with the knowledge and confidence to make the right decisions about how and where to store your application data.We begin by exploring why data is considered the lifeblood of modern applications, showing you real-world examples of how poor database choices can cripple even the most innovative ideas. You'll learn the differences between relational and NoSQL databases-when to prioritize strong consistency, and when horizontal scalability becomes paramount. We'll cover everything from core SQL and transactional data management to powerful NoSQL paradigms like document stores, key-value pairs, columnar data, and graph databases.But it doesn't stop there. This course dives into the practicalities of scaling databases, revealing strategies like read replicas, sharding, and distributed transactions, so your system can handle massive volumes of traffic without skipping a beat. You'll see how caching mechanisms (using tools like Redis or Memcached) offload work from primary databases, while file storage (such as Amazon S3) and content delivery networks (CDNs) optimize the handling of large static assets.Moreover, we take a close look at specialized time series databases, unveiling how they streamline real-time analytics for IoT devices, financial markets, and high-velocity logging. By comparing traditional relational systems to emerging NewSQL solutions, you'll get a front-row seat to the future of global-scale data consistency-ideal for mission-critical services such as payment processing or financial transactions.Throughout the course, you'll gain hands-on exposure to Java-based integrations. We'll discuss JDBC (Java Database Connectivity) for direct queries and explore how Object-Relational Mapping (ORM) frameworks-such as Hibernate and JPA-bridge the gap between object-oriented code and relational data. This full-stack perspective ties together the conceptual and the practical, ensuring you understand not just what to do, but also how to do it.By the end of Database Essentials for Backend Engineers, you'll have a powerful toolkit that combines deep conceptual insight with real-world techniques. You'll be ready to tackle system design interviews, craft robust backend architectures, and confidently select the right database solution to deliver high performance, reliability, and scalability-no matter the size or complexity of your application.
