fuzzy relational databases

Fuzzy relational databases are systems that handle information with uncertainty or partial truth, unlike traditional databases that require precise data. They use "fuzzy logic" to represent and manage data that isn't strictly true or false but can be somewhat true to varying degrees. For example, instead of saying an employee is either "highly experienced" or "not experienced," a fuzzy database might express their experience as 70% true. This approach allows for more flexible, realistic modeling of real-world scenarios where information is often incomplete or imprecise.
