An Object-Relational Data Warehouse Modelig for Complex Data
نویسندگان
چکیده
A data warehouse is an essential component to the decision support system. The traditional data warehouse provides only numeric and character data analysis. But as information technologies progress, complex data such as semi-structured and unstructured data become vastly used. Developing new data warehouse technologies to accommodate the demand of integrating complex data is important. In this paper, we propose a data model for the complex data warehouse. This model incorporates the well-known star schema with object-relational concepts, inheriting the easy-understanding and multidimensional characteristic, and providing mechanisms to integrate complex data in a data warehouse model.

A data warehouse (DW) is a database used for reporting Paper describes Object Oriented Data Warehousing using a narrower compassed data model. The data is offloaded from the operational systems for reporting. The data may pass through an operational data store for additional operations before it is used in the Data warehousing for reporting. An Object Oriented Data Warehouse system includes a d...

متن کاملMetadata for object-relational data warehouse
For developing data warehouse (DW) and OnLine Analytical Processing (OLAP) systems, the dominant relational database reaches its limitations. On the way of the development, object-relational (O-R) database is preferred to get over those ones. This paper introduces metadata for data warehouse system on O-R database and specifies new kind of metadata for mapping from object-oriented environment t...
