Abstract
A mechanism is provided in a data processing system for executing queries referencing data stored in a unified data layer. A relational engine executing on the data processing system receives a structured query language (SQL) query from a client. A query processor executing on the data processing system accesses integrated data sources including a unified data layer (UDL) data source storing UDL topic files via a data virtualization layer to form query results. The data virtualization layer projects the UDL topic files into relational form. The relational engine returns the query results to the client.
