Relational model for storing ecologico-biological expedition data

Eco-biological expedition research involves the collection of biotic and abiotic material (samples), which is attached to spatio-temporal location. Researchers often use the geographical name of the place instead of the geographical coordinates to indicate the spatial location of a sample. For this reason, an expedition information system must support work with geographical names. The article describes the structure of the expedition database, where the main emphasis is made on geographical names. A method of presenting the official and unofficial names of land and water bodies in a single table is proposed. This way of presenting geographic information makes working with the information system more people-friendly.
