- B. It introduces automation into all stages of app/database development.
- C. Development changes are automatically V tested on push/commits and merges.
- D. It requires Liquibase
正解：B、C
解説：
These are two characteristics of CI/CD, which is a set of practices that automate the building, testing, and deployment stages of software development. According to the Red Hat website9, "CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment." This means that CI/CD aims to reduce manual tasks and increase efficiency and reliability across the development life cycle. According to the IBM blog10, "Continuous integration (CI) is an automation process for developers. Successful CI means new code changes to an app are regularly built, tested, and merged to a shared repository." This means that CI/CD enables developers to integrate their code changes frequently and automatically, ensuring code quality and consistency.
