Sql 2014 | Express [updated]

Today, SQL 2014 Express lives in a strange purgatory. Its mainstream support is dead; its extended support has faded. It exists now as "zombie infrastructure." It powers the point-of-sale systems in old retail stores. It runs the backend of that inventory management software at the local mechanic’s shop that hasn't updated Windows in a decade.

It was the engineering equivalent of a survival instinct, a mechanism designed to prolong the life of hardware that was already nearing obsolescence. It runs the backend of that inventory management

A standout at the time: supports memory-optimized tables (though with constraints). Great for certain high-speed scenarios.
