A Paraconsistent Relational Data Model

  title={A Paraconsistent Relational Data Model},
  author={Rajiv Bagai},
We present a generalisation of the relational data model based on a 4-valued paraconsis-tent logic. Our data model is capable of manipulating incomplete as well as inconsistent information. For this model, we deene algebraic operators that are generalisations of the usual operators, such as union, selection, join, on ordinary relations. Our data model can underlie any database management system that deals with incomplete or inconsistent information. As another application of our model and its… CONTINUE READING
