Data in the system of conducting the State inventory of natural healing resources are preserved mainly in unstructured form. Accumulated information is not used efficiently. Data that has a structured form prefers fast updates, high speed updates, processing, and visualization. The use of GIS technologies together with object-relational database management systems provide an opportunity for high-quality and efficient storage, processing, analysis and visualization of geospatial information. In accordance with the modern methodology of geospatial data organization at the stage of database design, a conceptual modeling of data with cataloging of research objects is carried out. The result of this phase is the conceptual schema of the geodata database and the directory of the geodata database objects. The purpose of the article is to describe the conceptual schema of the database, the description of the structure and the Catalog of classes of objects of the base of the geodata of natural healing resources. Conceptual model allows you to outline the boundaries of the subject area, identify its main essence, the relationship between them.Each type of natural healing resources (mineral waters, mud, limestone and lakes, bishofite, ozokerite, seacoast, landscapes) is a separate class of objects. Non-spatial object classes are attributive data on qualitative, quantitative indicators, information on the subject of business, licensing. The relationship between classes is modeled in the form of associations that use the key fields of the corresponding attributes. All attribute fields have status: basic, non-core, and service. The catalog of objects classes contains a set of data in accordance with the list of data included in the State inventory of natural healing resources. Provides additional data that can complement the description of objects in the geodatabase. The catalog is presented in the form of an information table with the characteristics of each class, a list of attributes, data types, units of measure, domains and associations. Data types can have text, numeric, logical formats. For attributes that have a list of defined definitions, domains of admissible values are provided. Each geospatial object stores an abstract Geometry data type that provides information about the geographic location of an object.The maintenance of the State inventory of natural healing resources in the system of the Infrastructure of geospatial data of Ukraine is based on application of GIS technologies and object-relational DBMS. A conceptual scheme and a catalog of classes of objects of the geospatial data set of the State Cadastre of natural healing resources will be based on physical modeling in the environment of an object-relational database management system.
