The paper investigates several approaches for designing and implementing integration environments. Such an environment is developed for the purpose to allow cooperative interactions between distributed and heterogeneous systems. A possible approach to achieve system integration is to use the warehousing technology which engenders the development of data warehousing environments. These environments are information repositories that are available for queries and analysis. In order to manage efficiently a data warehouse, software agents enhanced with mobility mechanisms are introduced. A software agent is an autonomous entity having the abilities to collaborate with each other and to answer users' needs. Furthermore, to perform their operations software agents can migrate off their hosts and roam the network to gather relevant information. This research is part of the SAMDW project which aims at developing a new generation of data warehouses.
