KnowledgeBench includes an integration engine that takes information from a number of different types of source (relational data, XML, Web Services) and map them to a common object model. All the data from the different sources is available in the knowledgebase and is accessible for searching, display, and to the rules engine.

KnowledgeBench offers standard interfaces to most database systems including Oracle, MySQL and Microsoft SQL Server. It also has a Web Services and XML interface allowing Microsoft Office applications such as Excel to embed KnowledgeBench data into spreadsheets and documents.
