The Logical Data Warehouse (LDW) enables modern data architectures that democratize the data for business users while meeting strict requirements for security, data governance, and data lineage. Founded on the data virtualization technology, the LDW allows building a semantic layer in which data from various sources is made accessible through the virtual schemas and views in SQL.
Thereby, a central data access point is created for all data consumers in a secured and governed environment. The metadata is searchable so business users can easily find and work with the data, even in their web browser.
