Code First Approach

Code First is a software development methodology where developers write code to define the data model and database schema, rather than designing the database first. It is commonly used in Object-Relational Mapping (ORM) frameworks like Entity Framework to generate databases from code classes. This approach emphasizes a developer-centric workflow, allowing for rapid prototyping and easier version control of the data model.

Also known as: Code-First, Code First Development, Code-First Design, Code First ORM, EF Code First

Why learn Code First Approach?

Developers should use Code First when working with ORM tools in applications where the data model is likely to evolve frequently, such as in agile development environments or for startups. It is ideal for scenarios where you want to avoid manual database scripting, enable migrations for schema changes, and maintain a clean separation between code and database concerns, particularly in .NET applications with Entity Framework.
