    • Automatic generation of ETL processes from conceptual models 

      Muñoz, Lilia; Trujillo, Juan; Mazón, Jose Norberto (2009-11-06)
      Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...
    • Definición y validación de medidas para procesos ETL en almacenes de datos 

      Muñnoz, Lilia; Pardillo, Jesús; Norberto Mazón, José; Trujillo, Juan (2009-01-01)
      In data warehousing, ETL (Extract, Transform, and Load) processes are in charge of extracting the data from data sources that will be contained in the data warehouse. Due to their relevance, the quality of these processes ...
    • A family of experiments to validate measures for UML activity diagrams of ETL processes in data warehouses 

      Muñoz, Lilia; Mazón, Jose Norberto; Trujillo, Juan (2010-11-01)
      In data warehousing, Extract, Transform, and Load (ETL) processes are in charge of extracting the data from the data sources that will be contained in the data warehouse. Their design and maintenance is thus a cornerstone ...
    • Measures for ETL processes models in data warehouses 

      Muñoz, Lilia; Mazón, Jose Norberto; Trujillo, Juan (2009-11-06)
      processes take charge of extracting the data from data sources that would be contained in the data warehouse. Due to their relevance, the quality of these processes should be formally assessed since the early stages of ...
    • Modelling ETL processes of data warehouses with UML activity diagrams 

      Muñoz, Lilia; Mazón, Jose Norberto; Pardillo, Jesús; Trujillo, Juan (2008-11-09)
      Extraction-transformation-loading (ETL) processes play an important role in a data warehouse (DW) architecture because they are responsible of integrating data from heterogeneous data sources into the DW repository. ...
    • Systematic review and comparison of modeling ETL processes in data warehouse 

      Muñoz, Lilia; Mazón, Jose Norberto; Trujillo, Juan (2010-08-23)
      Abstract: In a Data Warehouse (DW), ETL processes (Extraction, Transformation, Load) are responsible for extracting, transforming and loading data from the data sources into the DW. A good design of these processes in the ...
