Abstract: Techniques for a data repository, e.g., a data warehouse, connect multiple disparate systems and combine different software tools to provide a full view of the data warehouse for an end user. An inventory tool integration and services interface includes a tool integration component, a common data component, and an inventory services component. The tool integration component obtains data sets from different tools. The common data component converts each data set and combines the converted data sets. The inventory services component provides the combined data sets through a user interface for an end user. The inventory tool integration and services interface appropriately combines data sets and supports different user interfaces for different end users having different roles within an enterprise. The tool and services integration interface also may obtain a data set from a tool in accordance with an integration option.
