Fast DB access

[Differentiated Software Solutions Pvt. Ltd]

Hi,   We have an application where we will have to service as high as 50 queries a second. We've discovered that most database just cannot keep pace.   The only option we know is to service queries out of flat files. Can somebody give us pointers o n what modules are available to create flat file based database. Specically we want a mechanism to be able service queries which can return rows where values are greater than specified value. We are experiementing currently with dbm and DB::File. These seem to handle hashes quite comfortably. How do we handle these inequality queries.   Thanks,   Murali   Differentiated Software Solutions Pvt.
