A METHOD FOR MINING FUNCTIONAL DEPENDENCIES IN RELATIONAL DATABASE DESIGN USING FCA. Authors: KATALIN TUNDE JANOSI-RANCZ, VIORICA VARGA. |

Abstract: Formal Concept Analysis (FCA) is a useful tool to explore the conceptual knowledge contained in a database by analyzing the formal conceptual structure of the data. In this paper, we present a new method to optimize and extend a previous research on FCA and databases, by analyzing the functional dependencies in order to correctly build database schemata. Our method intends to mine functional dependencies in a relational database table. The novelty of our method is that it builds inverted index files in order to optimize the construction of the formal context of functional dependencies. | |||||||
