Code-first approaches in software development, often referred to as code-first development, are a methodology where the primary focus is on writing the code that defines the application's logic and behavior. In this paradigm, the data model or database schema is derived from the code itself, rather than the other way around. This is in contrast to database-first or model-first approaches, where the database schema or a conceptual model is created first, and then the code is generated or adapted to match it.

When using a code-first approach, developers typically define their entities and relationships directly within their programming language, using classes and objects. Object-relational mapping (ORM) frameworks, such as Entity Framework in .NET or Hibernate in Java, play a crucial role. These frameworks then inspect the code-defined models and automatically generate the corresponding database schema, including tables, columns, and relationships. Changes made to the code are then reflected in the database through a migration process managed by the ORM.

The advantages of code-first development often include faster initial development cycles, as developers can concentrate on application logic without immediate concern for database design. It promotes a closer alignment between the application's object model and its persistence layer, potentially leading to cleaner and more maintainable code. However, it can also present challenges, particularly in complex scenarios or when integrating with existing databases, where reverse-engineering the code-first model might be difficult or less efficient than a more traditional schema-first approach.
