In this article we propose architecture for data warehouses based on an object-relational database management system. Thisarchitecture intends bine most advantages of mon data warehouse architectures. Based on this architecture, data warehouses can bedeveloped efficiently as object-oriented applicationsoftware. The flexibility is given by the introduction of a metadata layer in the object-relational datawarehouse : OLAP, Data warehouse architecture,Object-relational data that is stored in the data warehouse and OLAP systems is collected, integrated and centralized from various operational data store systems. Foranalysis purpose of the enterprise, the data are usually stored in multidimensional structures. Thesestructures are suitable for analysis purposes since they represent in an intuitive way the factual ording to the characteristics that are consideredrelevant to the warehousing is a kind of high-leve
