水田作一筆圃場管理システムにおけるデータベースの開発研究

We have been carrying out research on development of a personal computer software for rice field management in paddy farms' with the aim of supporting farm management functions in large-scale paddy farms. In this research, with the aim of strengthening the database management functions of this software, the following three types of functions were developed. 1) Functions to make blank maps, and data management functions for 6 farm management ledgers (land ledgers, cropping ledgers, production management ledgers, ledgers of partial farm work contract, etc). 2)Functions to make the software compatible with surveying and data analysis software. 3) Functions for time series analysis using yearly data from cropping ledgers, soil ledgers, rice quality ledgers, etc.
