alt Hacker NewsOracle database has unparalleled scalability. Ask someone who works at Microsoft SQL Server division what their bug database looks like. They will tell you that a single SQL Server instance cannot scale to the entire SQL Server division. Oracle on the other hand has a single database for the entire company. No other database is this scalable.
But Oracle is not just a database company. Oracle started as a database company, but today they are more an applications company than a database company. They have ERP back-office applications (finance, operations, HR), and CRM front-office applications (sales, marketing, service). Oracle bought a large number of applications software companies such as Seibel, PeopleSoft, JD Edwards, NetSuite and Cerner to become this big.
Of course Oracle is also a major cloud services provider and provide AI superclusters, and GPU instances from NVIDIA and AMD (context for today's layoffs).
I'm actually impressed by the amount of abuse our Oracle instances are able take from our developers.
Massive amounts of parallel single reads and writes with millisecond responses mixed with mega-joins of incorrectly indexed tables that works flawlessly "on their machine" that limp on well enough to sneak past performance testing with just the planner silently writhing in agony.
