Data Discovery and Query Builder (DDQB) is a data abstraction technology, developed by IBM, that allows users to retrieve information from a data warehouse, in terms of the user's specific area of expertise instead of SQL.

DDQB serves the user through a web based graphical user interface and configurable data abstraction model (DAM), which contains both an understanding of the user knowledge domain and the database below it.

DDQB uses a set of Eclipse-based customization tooling and can be deployed as a set of web services.
