Логическая реляционная модель структур данных для решения задач в предметной области управления землепользованием

| Abstract: | |
| The paper belongs to theoretical foundations of agroinformatics. To be more precise, it concerns development of methods and tools for automatization of land use management. A logical model for data structures intended for problem solving in the subject area is proposed. Registry for agroecological groups and types of lands organizing diversity of their geomorphological, soil, and agrochemical conditions, registry for crops and cultivars, and registry for agrotechnologies as complexes of technological operations for management of crop production processes are formalized as sets of relations of the relational data model and relationships between them. Application of the logical model is demonstrated via several generic problems of land use management. Each problem is implemented as a declarative query expression over the logical model. The model is implemented in a relational database management system.
