A Model for Data Warehouse Operational Processes
Previous research has provided metadata models that enable the capturing of the static components of a Data Warehouse (DW) architecture, along with information on different quality factors over these components. This paper complements this work with the modeling of the dynamic parts of the DW, i.e., with a metamodel for DW operational processes. The proposed metamodel is capable of modeling com...
متن کاملBuilding Secure Data Warehouse Schemas from Federated Information Systems
Introduction There are many heterogeneities among preexisting informations sources, such as DataBases (DBs), particularly semantic heterogeneities (see our chapter “Semantic Heterogeneity” in [1]). Any secure Federated Information Systems (FIS) must solve them, and deal with a): how schema levels are related to security, and b): operations on schemas to convert from level to level. We present t...
متن کاملMetadata Enrichment for Automatic Data Entry Based on Relational Data Models
The idea of automatic generation of data entry forms based on data relational models is a common and known idea that has been discussed day by day more than before according to the popularity of agile methods in software development accompanying development of programming tools. One of the requirements of the automation methods, whether in commercial products or the relevant research projects, ...
متن کاملDeriving Initial Data Warehouse Structures from the Conceptual Data Models of the Underlying Operational Information Systems
In recent years the construction of large scale data schemes for operational systems has been the major problem of conceptual data modeling for business needs. Multidimensional data structures used for decision support applications in data warehouses have rather different requirements to data modeling techniques. In case of operational systems the data models are created from application specif...
متن کاملA Strategy for Managing Data Quality in Data Warehouse Systems
High level data quality and the management of ensuring data quality is one of the key success factors for Data Warehousing projects. The following article describes an approach for Data Quality Management, which is based on theories as well as practical experiences. Starting from effects of insufficient data quality in practice, a definition for information, data and data quality will be worked...
