There are disclosed systems and methods which provide for an inter-action between unrelated databases such that information provided to a first database by a first provider can be pushed from the first database to a user based, at least in part, on data provided by that user to a second database unrelated to the first database. This then allows a user to have information pushed to him/her based upon information previously obtained from that user or about that user. In one embodiment, the user enters his/her information into one or more databases and the entered information forms the basis for information to be pushed to that user from any database even if the pushed information resides in a non-related database. In another embodiment, the data required from a provider is determined based upon data gathered from other providers for similar items. In some situations certain data is gathered without active participation from the provider.
