Tell about your experience with database migrations in projects.

In Java projects for database migrations, I usually used tools like Flyway or Liquibase. They allow managing database schema versions through migration scripts, which are applied sequentially and automatically when the application starts or during deployment.

Typical process:

• Create SQL scripts or XML/JSON descriptions of migrations.
• Scripts are numbered and stored in the project.
• When Flyway/Liquibase runs, it checks the current database version and applies new migrations.

This helps avoid issues with manual schema updates, provides version control, and simplifies teamwork. In some cases, I wrote migrations manually, especially for complex changes, but I always tried to use automation tools.
