Why are vector databases now a hot topic?

Not shocking but, most of the data scientists hadn't used a VectorDB until last year. But suddenly every business wants one in 2023.

But before we dive into it let's uncover a bit of history to get some context.

History of VectorDB

The history of vector databases dates back to the early 2000s, when researchers at the University of California, Berkeley began developing a new type of database specifically designed to store and query high-dimensional vectors.

The first commercial vector database was released in 2010 by the company VectorWise. VectorWise was later acquired by Actian in 2011.

In recent years, there has been a growing interest in vector databases, driven by the increasing popularity of artificial intelligence and machine learning applications. These applications often generate and use high-dimensional vectors to represent data.

One of the early uses for vector databases was to store and query high-dimensional data. This data could be anything from images to text to sensor data. Vector databases were able to do this efficiently because they were designed to take advantage of the unique properties of high-dimensional data.

For example, vector databases can use a technique called locality-sensitive hashing to quickly find similar data points in a high-dimensional space. This makes them ideal for applications such as image search, where users want to find images that are similar to a query image.

What is VectorDB in simple terms?

Imagine you have a vast library with thousands of books, each containing different information. Each book represents a unique topic, and inside each book, there are numerous paragraphs representing various ideas.

In the world of data, especially in areas like online shopping, recommendation systems, or understanding user behavior, we deal with enormous amounts of information. Each piece of data is like a book in the library, and within these pieces of data, there are intricate details represented as paragraphs.

Now, think of VectorDB as a super-smart librarian who knows the content of every book and every paragraph in the library. This librarian is incredibly efficient at organizing these books and paragraphs based on their themes and connections.

VectorDB essentially works like this librarian but in the digital world. It organizes vast amounts of data points (similar to paragraphs in books) based on their similarities and relationships. This organization helps businesses understand patterns in customer behavior, recommend products more accurately, and make smarter decisions based on the relationships between different pieces of information.

So, in simple terms, VectorDB is like a highly organized, super-efficient librarian for digital data. It helps businesses find meaningful patterns in the vast sea of information, making their services and recommendations more personalized and effective for users.

Why do you need a VectorDB?

Continuing with the above analogy of Liberian, Imagine a library that's not just big but absolutely enormous, with millions of books scattered around. Each book represents a different topic or interest area. Now, you walk into this library, hoping to find the perfect book that matches your interests.

Without a librarian, finding the right book would be like searching for a needle in a haystack. You'd have to wander around aimlessly, picking up random books, hoping one of them is what you're looking for. It would be time-consuming and frustrating.

Now, enter the librarian. The librarian knows every single book in the library and understands the content of each book, chapter, and even paragraph. When you approach the librarian and tell them what you're interested in, they guide you directly to the shelf where the perfect book is waiting for you.

In the digital world, our data is like those books in the library. We have tons of data points, each representing something different. VectorDB acts as the librarian. It organizes all these data points and understands their content. When we need specific information or want to find related data points (just like finding a book on a similar topic), VectorDB quickly guides us to the right data, making our searches efficient and effective.

So, in essence, we need VectorDB because it acts as the knowledgeable librarian in the vast library of digital data, helping us find what we're looking for without the hassle and confusion of searching blindly.

Popular VectorDB?

Today, there are a number of different vector databases available, both commercial and open source. Some of the most popular vector databases include:

• Pinecone
• Weaviate
• Chroma
• Milvus
• Annoy
• Faiss

Conclusion

In essence, vector databases are at the forefront of the data revolution, propelling industries toward a future where understanding data is not just a challenge but an opportunity. Their capacity to turn raw data into actionable insights is reshaping businesses, research endeavors, and technological innovations.

As businesses continue to explore the immense possibilities within their data, the conversation around vector databases will only intensify. Their ability to decipher the intricate language of data ensures that they will remain a hot topic, driving innovation, informed decision-making, and transformative discoveries in the years to come. The era of data enlightenment is here, and vector databases are the torchbearers lighting the way forward.
