Hands-On Development: Connecting APIs and Databases

Many applications rely on fetching data from external services or storing user information. Learning how to connect these essential pieces—APIs and databases—is the critical next step for any aspiring developer. By the end of this course, you will possess the practical skills necessary to design, implement, and test data-driven applications. You will understand the architecture behind modern applications that rely on external services and persistent storage. What you'll learn: * Understand the core principles of RESTful APIs, including request methods, status codes, and data formats. * Practice making secure, asynchronous requests to external web services and correctly handling responses. * Master fundamental SQL operations for defining, querying, and updating relational database schemas. * Apply best practices for handling configuration and sensitive data when connecting to external resources. * Build and structure multi-step practical projects that combine API interaction and data persistence. * Learn basic unit testing techniques to verify data handling logic and API integration points. This course begins with foundational terminology, covering the theory of client-server communication and database structure. You will then move into guided practical exercises that simulate real-world data retrieval and storage scenarios, reinforced by written tasks and code challenges. This course is designed for absolute beginners interested in software development who have basic programming familiarity but no prior experience with APIs or databases. No specialized prior knowledge is required. Start building robust, data-connected applications today.
