Asking ChatGPT About the Advantages of Db2 for z/OS over Oracle

If you read my blog post from yesterday, you know that I have been playing around with ChatGPT, the latest AI technology that is sweeping the headlines.

Yesterday I was asking it about the mainframe, but today I thought I'd ask ChatGPT about Db2 and Oracle, specifically:

In what ways is IBM Db2 for z/OS better than Oracle?

Yes, I know that is a loaded question and that the results would likely be different if I swapped the order of Db2 for z/OS and Oracle. Nevertheless, I liked the results that ChatGPT generated, so I figured I'd share them with everybody here!

So here is ChatGPT's reply:

"Both IBM Db2 for z/OS and Oracle are mature and widely used relational database management systems, and each has its strengths and weaknesses. However, here are some ways that IBM Db2 for z/OS might be considered better than Oracle:
Transaction Processing: Db2 for z/OS is known for its high performance and ability to handle large transaction processing workloads. It is optimized for OLTP (Online Transaction Processing) applications and can handle high concurrency and high throughput.
Security: IBM has a long-standing reputation for security, and Db2 for z/OS is no exception. It has a robust set of security features, including encryption, role-based access control, and auditing capabilities that help ensure that sensitive data is protected.
Cost: Db2 for z/OS can be less expensive to operate than Oracle for some use cases. It is designed to run on IBM mainframes, which are known for their scalability and efficiency, allowing organizations to reduce hardware and software costs. Additionally, because IBM mainframes are known for their reliability, uptime, and availability, they can help reduce costs associated with system downtime or data loss.
Integration: Db2 for z/OS can integrate with other IBM products and services, such as CICS (Customer Information Control System) and IMS (Information Management System). This can be particularly beneficial for organizations that already have an IBM infrastructure in place.
Built-in Analytics: Db2 for z/OS includes built-in analytics features, such as IBM Db2 Analytics Accelerator, which can help organizations to run complex analytics queries on large datasets. This can be particularly useful for organizations that need to process large amounts of data quickly and efficiently. 
It is worth noting that Oracle also has its own strengths and advantages, such as its support for a wide range of platforms and its focus on database consolidation. Ultimately, the choice between Db2 for z/OS and Oracle will depend on the specific needs and requirements of an organization."

Again, a quite reasonable response! I think the thing that jumped out at me the most here is the "Cost" section. As a grizzeled, old mainframer I am always ready to fight back against unfounded claims that the mainframe option is always the more espensive one. But ChatGPT didn't make that mistake! Maybe because Oracle has a reputation of being expensive, too?

At any rate, I look forward to asking ChatGPT for help in my future endeavors.

I'd also add that it is impressive that ChatGPT understood "Db2 for z/OS' as opposed to just "Db2" or "Db2 for LUW"... when you search the web it is quite common for the search results to confuse and conflate the two!

That may be the best part that it recognized the right Db2. Google has trouble with that!

"Additionally, because IBM mainframes are known for their reliability, uptime, and availability,".... I know it mentioned Db2 for z/OS security, but I think it should also be included in the mainframe portion of the response as well. IBM mainframes and z/OS are MUCH MORE secure that UNIX, Linux or Windows....
