Information system and database for simulation of irrigated crop growing

Abstract

Consideration has been given to the issues of creation of the information system for simulation and optimization of crop irrigation parameters, and logical database development model. The domain area of irrigated crop growing as well as the need for consideration of agricultural melioration parameters has been analyzed. 11 basic entities have been identified; their hierarchy and attributive characteristics have been defined. Logical relationships between entities have been established. The obtained attributive logical database model includes entities, attributes and relationships identified during the analysis of the domain area. The key attributes of entities of the database have been identified. Developed conceptual and logical database models made it possible to create a physical analog of the information system, focused on the support of managerial decision making for the simulation modeling of the consumptive water use of cultivated crops.
