Database Migration & Schema Management

About

This skill provides a comprehensive framework for managing database schema and data migrations using popular ORMs like Sequelize, TypeORM, and Prisma. It empowers developers to implement complex data transformations, perform cross-database migrations, and execute zero-downtime deployment strategies with built-in rollback procedures. By providing standardized patterns and best practices, it ensures data consistency and minimizes risk during structural database changes in production environments.
