Abstrak
Data warehouse which is generaly known as traditional data warehouse has some weaknesses on data modeling which has lead to the quality of the resulting data is not specific and ineffective. Semantic data warehouse system is the solution to solve the problems on traditional data warehouse because it has some advantages, such as: data quality management with the same data format to support a good OLAP report, along with a more effective performance with natural language keywords. The modeling of semantic data warehouse using ontology method produces logic resource description framework scheme (RDFS) model which later will be transformed into physical snowflake scheme. The academic report needed is produced through Kimball's nine step method and semanctic search using rule based method. The trial has been done with two trial methods namely black box testing and checklist questionnaire. From the findings of this research, it can be concluded that semantic data warehouse can help the academic data processing which produces good quality report to support decision making process.
