ChangeDatabase

ChangeDatabase is a command-line utility designed to facilitate database schema migrations. It allows developers to manage changes to their database structure in a controlled and versioned manner. The primary function of ChangeDatabase is to apply or revert database schema modifications defined in migration scripts.

Typically, migration scripts are stored in a structured directory and are written in a language or format that the database system understands, such as SQL. ChangeDatabase reads these scripts, tracks which migrations have already been applied to a given database, and then executes the necessary scripts to bring the database schema up to a specified version. This ensures that the database schema is consistent across different environments, such as development, testing, and production.

The tool often supports features like creating new migration scripts, viewing the current migration status, and rolling back previous migrations if an issue arises. By automating the migration process, ChangeDatabase helps prevent manual errors, improves collaboration among development teams, and simplifies the deployment of new database features. Its usage is common in software development workflows that involve frequent database updates.
