US Patent 7480644 Systems methods, and software for distributed loading of databases

The present inventors have devised one or more systems, methods, and software for distributed loading of information retrieval systems. One exemplary system includes two or more (at least two) load monitor servers that not only monitor and ensure completion of load tasks by individual load servers in a set of two or more load servers, but also provide for one load monitor to monitor performance of the another. Moreover, the exemplary system provides a service-level-agreement (SLA) data structure for each load server. The SLA data structure governs what types and priority levels of loading tasks will be performed for predetermined time periods.
