Incremental maintenance of data warehouses has attracted a lot of research attention for the past few years. Nevertheless, most of the previous work is confined to the relational setting. Recently, object-oriented data warehouses have been regarded as a better means to integrate data from modern heterogeneous data sources. However, existing approaches to incremental maintenance of data warehouses do not directly apply to object-oriented data warehouses. In this paper, therefore, we propose an approach to incremental maintenance of object-oriented data warehouses. We focus on two primary issues specifically. First, we identify six categories of potential updates to an object-oriented view and propose an algorithm to find potential updates from the definition of the view. Second, we propose an incremental view maintenance algorithm for maintaining object-oriented data warehouses. We have implemented a prototype system for incremental maintenance of object-oriented data warehouses. Performance evaluation has been conducted, which indicates that our approach is correct and efficient.
