That is not true. DBI is only portable, if the underlying databases have the same feature-set WRT the features you use. For example, DBI provides transactions, albeit not all databases implement them. Thus, to get portable transactions, all used databases have to support them. Another example of database abstraction is implemented in AOLserver. It is a minimalistic approach; it does not contain any of the advanced features found in DBI (i.e. BLOBs, transactions). I do like AOLserver's pools of database connections; they are comparable to PHP's persistent connections, but AOLserver implements them in a more general way. A useful PHP extension would have the following properties: - DBI's feature-set - AOLserver's pools Let me know what you think. -- Regards, Sascha Schumann Consultant
