However, usually Web log data are stored in flat files in different formats which hinders their analysis, thus obliging to use specific Web log analysis tools. In this context, approaches for structuring Web log data to better analyze them are highly...
Metadata repository acts like a backbone to a data warehouse as it stores and manages the metadata that is the basis for all the operations of a data warehouse. The generalized metadata repository presented in this paper is a comprehensive approach for creating a data warehouse from multiple and heterogeneous data sources in a semi-automatic way. The approach addresses all the issues involved in fetching...
In recent years, a number of requirements engineering (RE) proposals for a data warehouse (DW) systems have been made. In the traditional/operational systems, requirements engineering has been divided into two phases: early & late requirements engineering phase. Most of the data warehouse requirements engineering (DWRE) approaches have not distinguished early requirements engineering phase from...
A decision information system (DIS) is a specific component of information system specialized in the support of decision-making by means of online analytical processing tools. Data warehouses (DW), at the core of DIS, integrate and historize collections of data often designed starting from the operational components of the Information Systems (IS). Methods, techniques and tools widely used in the...
