Structured data refers to business data that's organized into specific formats based on the needs of the business. It's typically stored in tables and databases, making it easier for users to understand and utilize it. However, structured data has its limitations, such as being difficult to change and having limited use cases. In contrast, unstructured data is an amalgamation of data formats stored in data lakes, offering a wide range of format options that can be collected quickly and easily into a storage location. Unstructured data provides more granular information but requires specialized skills, tools, and expertise to analyze and work with it. Semi-structured data represents a bridge between structured and unstructured data, offering greater flexibility than structured data but not as well-defined as unstructured data.
