Databases & SQL
Schema design, normalisation, complex queries, indexing and the query that takes four minutes and should take four milliseconds.
A badly normalised schema causes problems forever; a missing index causes problems immediately. Both are cheap to fix early and expensive to fix later.
We design to third normal form (denormalising deliberately where reads justify it), write the queries, and read the execution plan rather than guessing at performance.
What you receive
- ER diagram and normalised schema
- DDL scripts with constraints and indexes
- Complex queries with joins, window functions and CTEs
- Execution-plan analysis for slow queries
- Sample data for testing
