Top 7 Vector Databases for AI

A decade ago, relational databases worked best for the kind of data that was being generated. All data was structured, organized, and stored in tabular format in relational databases. Unstructured data, such as pictures, videos, and audios, generally doesn’t fit in the relational database model since it cannot be sorted into rows and columns.?

This influx of unstructured data presented a challenge, as it defied the rules of traditional databases, making it difficult to efficiently manage, analyze, and utilize. This is a significant concern for businesses worldwide, as the International Data Corporation predicts that the global datasphere will reach 400 zettabytes by 2028, with 80% of that data being unstructured. However, a report by Deloitte states that only 18% of organizations are prepared?to face this challenge. This means that the vast majority of companies are unable to utilize the best part of the data in their current possession.

This clearly necessitates databases purpose-built for indexing and searching massive quantities of unstructured data. The solution to this is a vector database.?

Why Vector Database for AI?

A vector database sees data as a set of interconnected vectors. These vectors are multidimensional and can add numerous layers on top of each data point resulting in a rich dataset. They are built for handling the unique structure of vector embeddings. Vector databases are built with the purpose of handling the unique structure of vector embeddings. They index vectors to make it easy to search and retrieve by comparing values and finding those that are most similar to each other.

Vector databases have several advantages that can be utilized for AI. Some of these are:

• Efficient Data Retrieval:?Vector databases use indexing techniques that allow for fast and efficient data retrieval , making it easier to search and analyze large datasets. This is important for AI applications, which often requires processing huge amounts of data to identify patterns and make predictions.
• High-Dimensional Data Analysis:?Many AI applications deal with high-dimensional data, such as images or text, which can be difficult to analyze using traditional database structures. Vector databases use advanced mathematical techniques to represent and analyze high-dimensional data, enabling more accuracy and efficiency in the process.
• Machine Learning Integration:?Vector databases are designed to work seamlessly with machine learning algorithms, which can be used to analyze the data stored in the database. This integration allows for more sophisticated and accurate predictions, as well as real-time data processing.
• Scalability:?Vector databases are highly scalable, meaning they can handle large amounts of data and user requests without decelerating or crashing. This is essential for AI applications that require processing vast amounts of data in real-time.
• Flexibility:?Vector databases can be used for a wide range of AI applications, including natural language processing, computer vision, and recommendation systems. Their flexibility makes them a versatile tool for AI enthusiasts.
