MySQL Schema Design & Index Optimization

I will design or redesign your MySQL database schema — delivering a normalised, InnoDB-engine table structure with appropriate data types, PRIMARY KEY design (natural vs. surrogate), FOREIGN KEY constraints, UNIQUE constraints, CHECK constraints (MySQL 8.0+), index strategy for your query workload, and character set and collation configuration for your data requirements. MySQL schema design has platform-specific considerations — InnoDB clustered index behaviour makes primary key selection a performance decision, not just a design convention; incorrect character set configuration silently truncates or corrupts multi-byte character data; and TEXT and BLOB columns stored outside the row affect join performance in ways that differ from other databases.

The schema covers entity modelling, normalisation to 3NF, DDL with InnoDB engine, utf8mb4 character set and collation, AUTO_INCREMENT primary keys or UUID strategy with implications documented, FOREIGN KEY constraint syntax, covering index design for common queries, and a schema document with ERD and data dictionary.

Designed for developers and businesses building new MySQL-backed applications or redesigning an existing schema that has accumulated design problems.
