With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

This course implements a bulletin board CRUD using Spine, following the entire process from start to finish to see exactly which rules and sequences Spine uses to execute requests and complete responses. Based on Spine's core Execution Pipeline, we will examine the entire request lifecycle without omission: Routing (Handler selection) → Argument Resolution (Argument Resolver) → Controller Invocation (Invoker) → Return Value Processing (ReturnValue Handler). The focus is not on building features quickly. Instead, by directly tracing questions like "When is this logic executed?" and "Who is responsible for this step?" within Spine's architecture, you will develop the intuition to explain and control the execution flow. We also cover how cross-cutting concerns, such as logging, are separated from the controller and integrated into the execution flow (Interceptor). By the end of the bulletin board example, you will have gained something more important than just building CRUD with Spine: the criteria to determine where to attach specific features based on Spine's execution model. This is not just a simple CRUD course; it is the essential first course to truly getting started with Spine.

This course focuses more on data modeling through entity design than on JPA technical explanations. Based on the principle that solid DB design is the foundation of application development, we analyze various design patterns—such as one-to-many, many-to-many, inheritance, and collections—alongside business scenarios. You will learn by directly observing the process of code being transformed into actual tables on screen. To ensure immediate practical application, we provide business use cases, source code, and test codes for each design pattern.
