A method, system, and software for providing clinical data for analysis. purposes, includes storing clinical data, received from one or more data source sites, in a data repository. On receiving a request for data from the data repository from a user at a data source site, a working set of data is created responsive to the request from the user, and the user is provided access to the working set for analysis purposes. The working set of data is created such that at least some of the data in the working set is unchanged while the analysis is performed even if the data repository is updated while the analysis is performed, and working set only includes restricted data from other data source sites other than the data source site of the user.
