One of the targets of Sustainable Development Goals (SDGs 14) life below water addressed to coastal eutrophication, which has the primary problem that facing the most of coastal water bodies in worldwide areas. It is crucial to have a flexible analysis system for analyzing the dynamic coastal water-quality. So, this paper presents a new analysis system with a mathematical equation for Metadata analysis and eutrophication classification, which created in the database. The essence of this paper is to illustrate the meta-level knowledge of database for coastal eutrophication analysis. For the implementation of the Mathematical Equation for Metadata analysis and eutrophication classification found that Oligotrophic had 71 points, Mesotrophic had 148 points, Lower-eutrophic had 154 points, Eutrophic had 100 points, Upper-eutrophic had 49 points, Seriously-eutrophic had 31 points, Hyper-eutrophic had 13 points.
