Towards NoSQL-based Data Warehouse Solution integrating ECDIS for Maritime Navigation Decision Support System

Maritime shipping is a complex process because it requires continuous analysis of huge amounts information. Much this information has variable spatial and temporal properties. In addition, the must be effective to help in making decisions timely manner. Generally applied with Spatial On-Line Analytical Processing (SOLAP) basing on data warehouses SDW. Data warehousing by current technologies relational database management systems (RDBMS) cannot effectively manage increasing complexity volume geo-referenced data. order increase performance availability services, NoSQL databases have appeared. This paper presents modeling realization decision support system (SDSS) for maritime navigation namely “Maritima”, integration ECDIS OLAP systems. fact, spatio-multidimensional stored can benefit from expressive power electronic chart offered system. model advantages, we try apply transformations conceptual create document DW addition that, multidimensional at different dimensions aggregation levels generate beneficial indicators decision-aid very useful other steering secure navigation. Finally, “Maritima” tested set related two harbors “Arzew” “Oran” western Algeria.
