Mastering SQL Migrations: Strategies for Safe and Efficient Database Updates
Managing database migrations efficiently is critical to ensure the scalability, extensibility, and maintainability of applications that rely on relational databases. Migrations allow developers to apply consistent schema changes across environments, preventing issues that arise from version discrepancies. Using tools like TypeORM in NestJS, migrations are defined and executed through SQL scripts, with best practices such as batching updates, using transactions, and safely modifying schema elements to maintain database integrity. This systematic approach ensures that applications can evolve without compromising stability or performance.
