Development of Star-Schema Model for Lecturer Performance in Research Activities

Abstract

In this study, the researchers developed a multidimensional data model to investigate the activities of lecturers in universities in carrying out research activities as part of the Three Pillars of Higher Education. Information about lecturers' research activities has been managed using spreadsheet (excel) documents. Thus, access and analysis of the information were limited. Data warehouse development was carried out through several stages, namely requirement analysis, data source analysis, multidimensional modeling, ETL process, and reporting. The information generated in this data warehouse (DW) can be used as one of the business intelligence (BI) models in universities. In this study, the star-schema model was used in designing dimension tables and fact tables to facilitate and speed up the query process. The information generated in this study can be used by management in universities to make decisions and strategic planning. The results of this study can also be used as one of the important information in the preparation of institutional accreditation data and study program accreditation.
