The technology used for storing and managing unstructured data includes NoSQL databases and data lakes. Unlike traditional relational databases that require structured data, these technologies are designed to handle large volumes of varied data types, such as text, images, and videos. NoSQL databases, such as MongoDB and Cassandra, provide flexibility by allowing data to be stored without a predefined schema. Data lakes, on the other hand, ingest raw data and store it for analysis later, accommodating the ever-growing influx of unstructured data.
