Legacy applications that use mountains of PL/SQL to run business logic. It's possible to refactor this, but these systems are usually the backbone of things like a semiconductor factory, so you don't get a lot of room to play around with alternatives. Paying a billion dollars to keep the current stack running is worth it for a lot of orgs.
- chasil 4y agoI heard some time ago that Intel runs the VMS operating system on much of its production floor. DEC's relational database for this platform was Rdb. The Rdb database, originally written by DEC, was bought by Oracle in the '90s. It was actually the first commercial database to implement a "cost-based optimizer." https://en.wikipedia.org/wiki/Oracle_Rdb https://en.wikipedia.org/wiki/Oracle_Rdb It was purchased by Oracle, is still maintained, and is likely on Intel's VMS systems. https://www.oracle.com/database/technologies/related/rdb.html https://www.oracle.com/database/technologies/related/rdb.htm... (I also have an account on a system that runs it.)
