(English Abstract)
DBMS is advancing over the years and many of them are specialized in its own field. However, there are still many obstacles in combining and choosing these DBMS to get desired function. Predicting avalanche is one of these examples as this problem needs to efficiently process two difficult questions in one system. One is ability to execute realtime updating rainfall data which needs technology of stream data management and the other is finding closest weather observation station for each avalanche candidate site which needs spatial index to perform spatial query. In this paper we compare and evaluate several stream management system to pick best component for our system and evaluate the completed system to check its quality. Depending on survey we choose some components for our system. First, for stream data management we chose PipelineDB which is PostgreSQL with stream management system to process stream data. Second, for spatial query occurred by finding two closest point, we chose PostgreSQL extension PostGIS to settle this problem. Finally we complete our system by adding QGIS to show all the result we made from the system to users by visualizing it and accept input from them. To verify our selections, we use real query which used to predict avalanche possibility in our system and compare its results with non-modified DBMS result to show how much system made it better to get the results.
