Alibaba MySQL standards enforce lowercase table and column names, unsigned numeric data types, mandatory audit fields like create_time and update_time, and naming conventions for keys to prevent schema drift in Java applications.

To enforce ORM mapping best practices, ensure explicit result mappings, avoid using select * queries, and align database fields directly with Java objects to maintain safe query patterns and prevent schema drift.

Planning indexes involves advising on unique and composite indexes, avoiding unnecessary full-table scans, and promoting safe query patterns to optimize database performance and adhere to database standards.

Yes, you can apply these database standards to existing Java projects by enforcing schema conventions, indexing rules, and ORM mappings during schema design, index planning, SQL writing, and ORM mapping phases.

Mandatory audit fields like create_time and update_time are required by Alibaba database standards to ensure consistent data tracking, prevent schema drift, and maintain standardized auditing across Java applications.
