Logical design of data warehouses (DW) encompasses the sequence of steps which, given a core work- load, determine the logical scheme for the DW. A key step in logical design is view materialization. In this paper we propose an original approach to materialization in which the workload is ...

4.1.5.2 Logical Data Models Logical data models are more technical in nature and often represent the scope of the data for a particular automation effort or project. Logical data modeling belongs to the logical design phase as a data engineering step within the SDLC. Logical data models also ut...
You are now going to create datasets by importing the tables and views from the connected data warehouse to the LDM Modeler. When a table/view is being imported, the LDM Modeler tries to auto-detect the types of the data in the table/view. The data can be ...
The data model must be both precise and flexible. Along with the chosen software solutions, which are often open-source, the design of the data model must be ready to support Big Data and HPC from the outset. And as the customer’s data volume increases, data models must also support its...
