Specialist SQL writers, matched to your university

SQL is the universal language for relational databases. Assignments cover: SELECT queries (joins: INNER / LEFT / RIGHT / FULL / CROSS, subqueries, derived tables, CTEs, window functions with PARTITION BY / ORDER BY, GROUP BY / HAVING, aggregate functions), DDL (CREATE / ALTER / DROP TABLE, constraints, indexes), DML (INSERT / UPDATE / DELETE / MERGE / UPSERT), transactions (ACID, isolation levels, locks, deadlocks), indexes (B-tree, bitmap, covering, composite), stored procedures (PL/pgSQL, T-SQL, PL/SQL), triggers, views (materialised / non-materialised), query optimisation (EXPLAIN plans, index usage, query rewriting), and normalisation (functional dependencies, 1NF / 2NF / 3NF / BCNF proofs).

Our SQL writers know PostgreSQL, MySQL, SQL Server, Oracle, and SQLite. They deliver.sql files with clean, properly-indented queries, optimised for the specific database platform.
