I'm looking for a package to store very large (tens to hundreds of millions) numbers of tuples on disk for rapid access from Smalltalk-80. This means that it needs an interface that can be reached from C. It needs to be able to store strings, floating-point values and (32bit) integers; the main indexing will be on the integers. It is essential that there is very fast access to sets of tuples matching a certain combination of (integer) key fields; slower access on range, floating point and string queries is allowable. What we most emphatically do *not* want is to access the package via SQL. Oh yes, the other constraint: this miracle package must run on PCs, Apple Macs and UNIX boxes. The things that I have heard about are Sybase and various B-tree and B+tree packages. We'd be quite happy with a B+tree package, but need one that will deal with several-hundred-megabyte relations. E-mail ideas or expressions of interest to me please; I will summarise to the net if enough 'Me too' requests are received. Oh yes... price is (within reason) no object. Everything from PD to pay-per-machine required. advTHANXance, - Peter -- Peter Crowther, Medical Informatics Group, Dept. of Computer Science, University of Manchester, Manchester M13 9PL, England.
