This study was carried out to develop database system using internet for greenhouse. The database system consisted of group monitor, client monitor, server monitor and DBMS. The results of the study are summarized as follows. 1.The monitoring module, as data collection system for database, could monitor the state of the control device and the greenhouse environment. 2.The group monitor was connected to the house monitors by RS-485 communication method. Data received by the group monitor were sent to the server monitor and then stored in database server by TCP/IP and MIDAS. 3.The data of database consisted of on growing environment, control devices, operation and cultivation data in greenhouse. It was developed using MS-SQL server. 4.Remote monitoring of greenhouse was realized in a client/server environment. The client module, which was named as the client monitor, made requests to access the measurement data of greenhouse through the remote data module of the monitor in internet environment.
