Structured Query Language (SQL) has been the workhorse for anything
to do with data for many decades and it is still the language of choice for the
majority of applications. Over the years I have used it for everything from
hand-held scientific instruments to major commercial applications.
I can provide training
ranging from a one-day introduction through to a more comprehensive coverage over 3 or 4
days. I can also combine it with my language courses to show how it can be used in
bespoke applications. I use SQL Server most often, but can also
train using MySQL, MariaDB, PostgreSQL, SQLite and even Access. The outline below assumes
SQL Server over 3 or 4 days.
