Yeah, many of these comments are extremely misinformed. Oracle has been an application software vendor for a long time.

For example, Oracle sell Opera. Opera manages hotels, both individual and chains. And integrates with their amusement park management software.

People complain about them, but software like that is much closer to an sdk than a finished product. It is generally customized for each buyer for their needs. And the quality of the customization is more on the buyer than on Oracle.

Oracle have a giant suite of these products for POS, guest experiences, amusement parks, hospitality, marketing (b2b and b2c), etc. And companies buy from Oracle because they're not good at making software and because you do leverage some economies of scale.
