Diploma in Databases and T-SQL

Go deep into SQL and T-SQL — learn to write queries, manage databases, handle transactions, and extract insight from structured data.

SQL is the most important technical skill a data analyst can have. Without it, your access to data is limited to whatever has already been exported into a spreadsheet — with it, you can query millions of records, combine data from multiple tables, and retrieve precisely the information you need, directly from a live database. This comprehensive diploma teaches both standard SQL and Microsoft's powerful Transact-SQL (T-SQL) variant, giving you skills that are directly applicable in SQL Server environments used across enterprise organisations worldwide. The course begins with the core concepts of database structure, then rapidly builds your querying ability: SELECT statements to retrieve data, WHERE clauses to filter it, GROUP BY to aggregate it, and JOIN operations to combine data from multiple related tables. You will learn T-SQL's extended capabilities including built-in functions, aggregate operations, and subqueries — the building blocks of complex analytical reports. The diploma also covers the administrative side of SQL Server: managing security, handling errors gracefully, and controlling transactions to ensure data integrity in multi-user environments. By completing this diploma, you will have the technical foundation to query real-world databases, write reports that pull live data, and communicate confidently with database administrators and data engineers on the technical requirements of your analysis.
