Most databases easily scale up to 1 TB of data (ie. each cell could well use 10kB data). Beyond that it's more a matter of the right hardware. It's generally not a good idea to try to reinvent database technology from scratch by e.g. using text files. Instead, you should leverage all the features available in modern databases, such as indexes (of various kinds), search, transactions, compression, careful caching, etc. etc. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Jul 06 2009) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try our new mxODBC.Connect Python Database Interface for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.

I?ve already contacted Anthony Tuininga - contact on cxtools.net to ask for the binaries but at the present time it?s not possible to access a 64 bits machine and compile the code and provide me the binary files. Can someone help me on this issue? Has someone already compiled the code for 64 bits windows machine? best regards Pedro Andr?
