Standardize MySQL data models by injecting mandatory audit fields like version, is_deleted, created_time, and modified_time into every table schema with enforced NOT NULL constraints and consistent default values.

To enforce NOT NULL compliance in MySQL schemas, assign default values to all non-primary key fields: use 0 for numeric types and an empty string '' for string types, ensuring data integrity and avoiding null insertion errors.

Generate a standardized CREATE TABLE DDL template by including six mandatory audit fields, defining default values for all non-primary key columns, using datetime(3) for time fields, and adding consistent column comments.

Yes, this MySQL schema design approach requires using datetime(3) for all time fields to ensure millisecond precision and standardize temporal data tracking across modified_time and created_time audit columns.

Enforcing default values and audit fields in every MySQL table limits schema flexibility by requiring all non-primary key columns to have defaults and mandating six specific tracking columns, which may increase storage overhead.

Yes, you can use this data model design approach when modifying existing MySQL database schemas to retrofit standardized audit fields, enforce default values, and align table structures with project compliance standards.
