Abstract: Due to the fast growing of data in the digital world, not only in volume but also in its variety (structured, unstructured or hybrid), traditional RDBMS are complemented with a rich set of systems, known as NoSQL. One of the main categories of NoSQL databases are document stores which are specically designed to handle semi-structured data, for instance XML documents. In this paper, we present a modeling method for semi-structured data based on Conceptual Graphs and exemplify the method on an XML document. The expressive power of Conceptual Graphs makes them particularly suitable for conceptual modeling of semi-structured data.
Keywords: Conceptual Graphs, conceptual modeling, semi-structured data
