3. WEB BASED DATABASE MANAGEMENT SYSTEM Cloud-based web data monitoring service is available with major geotechnical instrumentation service providers for retrieving data from the dataloggers, archiving retrieved data in a SQL database, processing data and presenting the processed data in tabular and most suitable graphical forms (Fig. 9) for easy interpretation of logged data. This is a highly flexible online monitoring system that can combine data from structural, geodetic and environmental sensors. Cloud-based WDMS usually work on a rental model. The user has to pay a small setup fee for the first time and then a monthly rental has to be paid for accessing the data over the cloud as long as required. Web data monitoring service’s database management software acts as a data collection agent, a database server and a web server and is hosted on a high-reliability server computer. Choice of the software depends on the measurement technologies deployed. A master plan of the project is incorporated into the database with locations of each monitoring sensor. From this master plan, the user can get data in the graphical form of any sensor with just a mouse click. Fig. 9 Graphical data presentation on WDMS 1309
