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

 Many Omnidex Grids are created as an Omnidex Snapshot, meaning that the underlying data is distributed into flat files across multiple directories or servers. ​ These become very high-performing databases that can satisfy a wide variety of queries very quickly. ​ Omnidex Grids can also be created against the underlying database, though the nodes then remain tethered to the servers hosting the database.  ​ Many Omnidex Grids are created as an Omnidex Snapshot, meaning that the underlying data is distributed into flat files across multiple directories or servers. ​ These become very high-performing databases that can satisfy a wide variety of queries very quickly. ​ Omnidex Grids can also be created against the underlying database, though the nodes then remain tethered to the servers hosting the database.  ​
