Dive into the intriguing world of Data Oriented Programming (DOP), where data takes center stage for cleaner, more efficient code. Discover how well-modeled data minimizes defensive logic and enhances stability in applications. Explore the nuances of DOP compared to Object Oriented and Functional Programming, and learn about the significance of precise data modeling. You'll also find valuable insights into Kotlin and Java's support for DOP, along with practical examples and resource recommendations to boost your programming skills.

ADVICE

Model Data Deliberately

  • When modeling data, ask critical questions about its properties and constraints.
  • This upfront thinking clarifies data representation and reduces the need for extensive validation logic later.
INSIGHT

Expressive Data Types

  • Using more specific data types, like UUIDs instead of strings for IDs, automatically enforces constraints and reduces ambiguity.
  • Well-modeled data requires fewer defensive methods in business logic.
INSIGHT

Model API Responses Explicitly

  • Model all possible API response types explicitly using sealed classes or interfaces.
  • This eliminates ambiguity, simplifies error handling, and improves code clarity.
