Databases represent a highly developed form of data organisation. The efficient use of databases by their beneficiaries is a permanent and stringent concern. The first part of the article presents a short development of the way data are organised and of the ways distributed databases can be optimised in computer networks. Then, two means for the efficient operation of distributed databases are shown. The last part of the paper evaluations of the architectures of some data warehouses (DW) and of their building are made. Using the data warehouse, a beneficiary can prepare in advance the required support to get reports and then make the right decisions in specific situations.
