Unstructured data is a significant challenge in the modern enterprise, with over 90% of generated data being unstructured and lacking a fixed schema. Extract, Transform, and Load (ETL) processes were initially designed for structured data but have been adapted to handle unstructured data using advanced techniques like natural language processing (NLP) and machine learning (ML). Modern ETL tools offer robust solutions for processing and integrating unstructured data, including Airbyte, Fivetran, Unstructured.io, Unstructured AI, VectorETL, and Unstract. These tools address challenges such as data variety, lack of schema, transformation complexity, and integration difficulties. By selecting the right ETL tool and integrating it with vector databases like Milvus, businesses can unlock hidden insights from unstructured data, break down data silos, enhance generative AI applications, and drive innovation.
