# Design Patterns
Design patterns are typical solutions to commonly occurring problems in software design. They can be broken into three categories:
- Creational Patterns for the creation of objects
- Structural Patterns to provide relationship between objects
- Behavioral Patterns to help define how objects interact

# Migrations
Database migrations are a version-controlled way to manage and apply incremental changes to a database schema over time, allowing developers to modify the database structure (e.g., adding tables, altering columns) without affecting existing data. They ensure that the database evolves alongside application code in a consistent, repeatable manner across environments (e.g., development, testing, production), while maintaining compatibility with older versions of the schema. Migrations are typically written in SQL or a database-agnostic language, and are executed using migration tools like Liquibase, Flyway, or built-in ORM features such as Django or Rails migrations.
