Greetings, database enthusiasts! Today, we're diving into the exciting world of Retrieval-Augmented Generation (RAG) systems.  Here I 'am blogging again. This time with the motivation of Oracle Database 23 AI's vector capabilities, that we leveraged while building ourselves a Sales Assistant. While leveraging the power of Oracle 23AI, we also used OCI 's and Cohere's large language models (and integrations), and Flask for building our solution. This AI bases Sales Assistant is in beta version, but we can make it production ready by putting a little more effort, and making it reach perfect ..read more

Let's protect our confidential information, our secrets with mechanisms and algorithms that are computationally difficult to break. Think ahead and make your crypto system be ready for the future. Post Quantum Cryptography it is . Be quantum-proof, quantum-safe, quantum-resistant.. Enough for the passioned intro :) I received my second certificate in IBM quantum and I am sharing it here. More to come :) This was for being able to understand the foundations of cryptography, how the cybersecurity risk landscape is evolving in the quantum era, and how to protect against such threats throug ..read more

I received my first certificate in IBM quantum and I am sharing it here. More to come :) This was for being able to describe quantum information at a foundational level. While preparing, you learn how to describe fundamental concepts, such as quantum teleportation, superdense coding, and the Clauser, Horne, Shimony, and Holt (CHSH) game — all of which are connected to the phenomenon of entanglement.  By studying these, you gain the core skills required to explore deeper fundamental quantum algorithms and start using Qiskit Runtime ..read more

EBS Workflow Mailer  A Tale of Two Mysteries  Alright folks, buckle up for some classic EBS weirdness! This one involves the Workflow Notification Mailer in a fresh Oracle EBS 12.2.11 project. We got it all configured, tested it – IMAP, SMTP, everything seemed okay. But then, like a magic trick gone wrong, emails stopped flowing.  The customer's mail admin checked the server logs, but saw nothing. Their words? "Your mailer taps the SMTP server on the shoulder, then just walks away. No emails, no nothin'." We chased network packets, analyzed traces – same story. The mailer wasn ..read more

  Oracle Database 23AI Vector Search: A Game Changer for Enterprise Search Hey everyone, Erman Arslan here. Today, I'm diving into a revolutionary new feature in Oracle Database 23AI: Vector Search. This technology promises to completely transform how you search for information, especially within your enterprise data. Understanding Semantics Through Vectors Imagine searching for data based on meaning, not just keywords. That's the power of Vector Search. It uses machine learning embedding models, like ResNet for images and Bert for text, to convert your data into vectors. These vectors re ..read more

Educability.. We all need it, and here in this blog and in my forum, I think we are taking steps in this regard. Educability is defined with 3 basic things.  1) Learning from experience ( PAC - Probably approximately correct learning) 2) Chaining together what we've learned in different contexts.  3) Taking from someone else, their experience. It is actually the combination of those 3.. We, humans have this unique capability. So why not we use it in every way that we can? :) So you encounter some problems, you ask them, I try to shed some light on them and offer some solution ..read more
