Skill Profile
Database Modelling
"The observable action of designing the structure of a database — choosing how data is organised, related, and indexed to serve the queries and operations a system needs."
YOUR SKILLS
Problems This Skill Solves
- A query that should take milliseconds takes 30 seconds because the data was modelled without query patterns in mind.
- Adding a new feature requires a painful database migration because the original schema was too rigid.
- Reports are wrong because duplicate data in the database has drifted out of sync.
- An application cannot scale because every operation hits the same table with no partitioning strategy.

Technology / Software / Product
"Normalisation is always better"
Normalisation reduces duplication but increases joins — many high-performance systems deliberately denormalise for read speed.
"NoSQL is always faster than SQL"
Performance depends on the access patterns; relational databases with good indexes frequently outperform NoSQL for many use cases.
Research & Outlook
Data is the persistent layer beneath all software. Engineers who understand data modelling make better decisions at every layer of the stack.

Growth Path
How to Practise
- 1.Model a real-world domain (e-commerce, library, clinic) as a relational schema
- 2.Learn the difference between normalisation and denormalisation through practice
- 3.Explore NoSQL modelling patterns alongside relational ones
How to Prove
- ·Database schema with documented design decisions and trade-offs
- ·Query optimisation that measurably improved performance
