| Omnidex Grids are a feature of the Omnidex product line that allow large databases to be distributed across multiple processors or servers. This improves performance by allowing a query to be processed on the fewest nodes possible using multiple concurrent processors. This approach allows great scalability and provides convenient mechanisms for adding new data to the database. | Omnidex Grids are a feature of the Omnidex product line that allow large databases to be distributed across multiple processors or servers.

| - | An Omnidex Grid consists of one or more computers used in combination to satisfy Omnidex queries. Some Omnidex Grid’s are placed on one or more large, multi-processor computers. Other Omnidex Grid’s are placed on an array of inexpensive, commodity, desktop PC’s. Both types of grids perform well, and each has distinct advantages. | + | An Omnidex Grid consists of one or more computers used in combination to satisfy Omnidex queries.

| An Omnidex Grid always will have a //grid controller// and a collection of //grid nodes//. The grid controller coordinates all activity on the grid and communicates between the user and the underlying //grid nodes//. The //grid nodes// perform all of the work of housing and indexing the data, and fulfilling the queries. The //grid controller// and the //grid nodes// may all be on the same computer, or they may be distributed between multiple //grid servers// as needed for performance and scalability. | An Omnidex Grid always will have a //grid controller// and a collection of //grid nodes//.
