A network based survey system utilizing links from client sites to a set of logical servers to establish communication between users of the client sites and the survey system. The system preferably selects a percentage of the available users for participation in the survey using an adaptive selection process which adjusts to the load on the system. Preferably, users are deterministically mapped to a single one of a set of available servers, allowing user profile information to be stored only on a single server. The profile information can be used to allow a user to continue a survey at a later time or to implement question skip patterns or other traditional survey techniques. Alternatively, a central database is provided to collect, store, and process survey results. |
