What you have described is an implementation detail that should be hidden from the user. Secondly I'm not even sure I understand what it means. However, I do understand that to start a transaction, perform a query or an update I need to first grab some collection object and then grab a service object from it. So if I grab a the "/db/my_collection/xsl/" collection and obtain a query service or transaction service. Does this mean that I can't use this object to start a transaction or perform a query if I'll be performing operations on the "/db/schemas/" collection? If the answer to the above question is Yes, then this is an issue that will cause user confusion and perhaps errors (standardization on getting services from the DB root would help but then defeats the purpose of tying services to collections in the first place). If the answer is No, then there doesn't seem to be any justification in tying services to collections. ===== LAWS OF COMPUTER PROGRAMMING, VIII Any non-trivial program contains at least one bug. http://www.25hoursaday.com Carnage4Life (slashdot/advogato/kuro5hin) __________________________________________________ Do You Yahoo!?
