What you get with this Offer
I will review your existing database design or entity-relationship diagram and deliver a detailed consultation report covering normalisation issues, missing constraints, data type selection problems, relationship cardinality errors, naming convention inconsistencies, and scalability concerns — with specific remediation recommendations for every finding. Database design errors are the most expensive type of technical debt because they become harder and more disruptive to fix as data volumes grow and more application code becomes dependent on the schema.
The review covers normalisation assessment (1NF through 3NF violations), primary and foreign key constraint completeness, data type appropriateness and storage efficiency, NULL usage and NOT NULL constraint application, unique constraint coverage, referential integrity and cascade rule design, and naming convention consistency. Each finding is categorised by severity with a specific schema change recommendation.
This service is the right starting point for developers and teams who are designing a new database or who have inherited an existing schema and need an expert assessment before building further on top of it.
