Hyperlog is a graph-based declarative language which supports both queries and updates over the Hypernode Model. By requiring only a very small number of graphical constructs, Hyperlog is well-suited to non-expert database users. This paper is concerned with the implementation of Hyperlog, concentrating in particular on its graphical aspects. Key issues addressed include the following: We begin the paper with a brief introduction to Hyperlog in Section 2, which sets the scene for the rest of the paper. In Section 3 we describe the architecture of our implementation. Section 4 is the key section of the paper and is concerned with the graphical aspects of the implementation, covering the above points. Section 5 compares Hyperlog with other graph-based database languages and highlights some of its distinguishing features. Finally, Section 6 gives our concluding remarks and directions of further work.
