Entity vs Value

-

 Entity

- Entity has a identifier. The identifier is unique for each entity. That's why each entity has a different identifier from each other. 

The timing of generating an entity's identifier varies depending on the characteristics of the domain and the technology used.

  • Generates based on specific rules
  • UUID or Nano ID -> Unique Identifier Generator
  • Manually input value
  • Serial Number

Value

- A value type is used to represent a conceptually complete whole.

@ModelAttribute vs @RequestBody in Validation

Image
1. What is @ModelAttribute? What does it do? @ModelAttribute is primarily used to bind request data like HTML form data or query parameters (e.g., ?name=abc&price=100) to objects. In other words, it converts data entered by users in forms into objects that can be easily handled by controllers. How does it work? It maps HTTP request parameters (e.g., name, price) individually to object properties on a field-by-field basis. For example, if an ItemSaveForm object has name and price fields, request parameters name="book" and price=1000 would be set as itemSaveForm.setName("book"), itemSaveForm.setPrice(1000). Important characteristic : Even if there's a problem with one field (e.g., price has an invalid value like "abc" that can't be converted to a number), the other fields (e.g., name) are still bound normally. It has a structure that can partially succeed. Advantages: Flexibility: Since it processes on a field-by-field basis, even if certain fiel...

Side Project(a self-imposed 3-day "Hackathon" challenge)

-
Excited to share my side project(a self-imposed 3-day "Hackathon" challenge! 🤣) built with React, TypeScript, Node.js, and Express.js! I created this app for my wife to help her study Korean, using a custom CSV dataset I generated with Grok 3. Right now, she’s using it locally on her laptop, and it’s been a great tool for her learning journey. If you’re interested in learning Korean in English, I think this could be a helpful resource! Check out the GitHub repository here: https://github.com/bitcham/Korean?tab=readme-ov-file Open to feedback! Let me know what you think.

Google: The King is Back

-
When OpenAI released ChatGPT, many believed Google had been dethroned from its position as the king of AI. However, without much fanfare, Google has been steadily driving innovation in artificial intelligence. Not just in models, but also in features and practical applications. As the giant behind platforms like Google Maps, YouTube, and Google Search, Google is now shining brightly in the realm of multimodal AI generation. In this post, I’d like to dive into Google’s recent AI advancements, spotlighting Gemini 2.0, Gemma 3, and the exciting features of the Gemini App. Gemini 2.0: Mastering Image Manipulation and Generation Gemini 2.0 is a powerhouse AI model that takes image manipulation and generation to the next level. It can effortlessly edit and enhance photos by removing unwanted objects, reshaping elements, or even creating realistic passport photos from existing images. This impressive capability stems from Google’s use of Tensor Processing Units (TPUs), which optimize learni...
