Translation Methodology Based on Metamodel of Complex Structure for Database Design
The authors propose a software layer called GUEDOS-DB upon Object-Relational Database Management System ORDMS. In this paper, they apply it in Molecular Biology, more precisely Organelle (mitochondria and chloroplasts) complete genome. They aim to offer biologists the possibility to access in a unified way information spread among heterogeneous genome databanks. In this paper, the goal is firstly, to provide a visual schema graph through a number of illustrative examples. The adopted, human-computer interaction technique in this visual designing and querying makes very easy for biologists to formulate database queries compared with linear textual query representation.
