👉 The Fluid column in a database is an advanced data modeling technique designed to handle complex and evolving data relationships, particularly those involving semi-structured or unstructured data. It consists of three primary columns: 'Key' (also known as the Column Key), 'Value' (or 'Column Value'), and 'Ref' (or 'Reference'). The 'Key' column uniquely identifies a row within the fluid, while the 'Value' column stores the actual data. The 'Ref' column contains a reference to another table or entity, allowing for efficient and flexible data linking. This structure enables fluid to manage hierarchical, nested, or associative data models without the need for predefined schemas, making it highly adaptable to changing business requirements and data complexities.
