## From Relational to Intelligence: Unlocking Your Database's AI Potential
The Artificial Intelligence (AI) revolution is reshaping industries and how we interact with technology. For many, AI seems like a distant universe, accessible only to startups with unlimited budgets. But what if I told you the key to unlocking AI's power might already be in your hands, in a place you least expect: your relational database?
In this post, we'll embark on a technical journey to transform your trusty relational database into a powerful source of AI insights. We'll explore how to leverage your existing data, using modern development practices with TypeScript and Node.js, to build intelligent applications.
Relational databases, like PostgreSQL, MySQL, and SQL Server, are the backbone of countless applications. They store structured data in an organized manner, enabling efficient queries and referential integrity. However, they were not traditionally designed to handle the complexities of unstructured data or to perform machine learning inferences directly.
The data explosion—text, images, audio, and video—presents a challenge. How can we extract predictive value and actionable insights from these vast relational data repositories, which often contain crucial information for smart decision-making?
The answer lies in two powerful techniques: vectorization and the rise of vector databases.
Vectorization: This is the process of converting data (text, images, etc.) into high-dimensional numerical representations called \"vectors\" or \"embeddings.\" Trained AI models (like those from OpenAI, Google, or open-source models) perform this conversion, capturing the semantics and context of the data. Similar data will have vectors close to each other in the multidimensional space.
Vector Databases: These are databases optimized for storing and querying these high-dimensional vectors efficiently. They allow you to find vectors \"similar\" to a query vector, which is the foundation for many AI applications like semantic search, recommendation systems, and anomaly detection.
But the good news is you don't need to migrate your entire relational database to a dedicated vector database. We can integrate vector functionality into your existing system.
Many modern relational databases now support extensions or data types that allow for efficient storage and querying of vectors. The pgvector extension for PostgreSQL is a prominent example. It adds a vector data type and operators t
