When you do more, eventually things may take a little longer when you do less. This should be obvious. Anyway, if you really care about portability, you're only way out is Metabase. If you are in doubt about the features, think at least about what you can do with each package to migrate your data when you decide to switch databases. Metabase is the only package that offer painless and failure proof method of migrating data using the XML schema support. With the other package you need to write custom scripts for migration which is a real pain and prone to error due to eventual bugs of software that you need to write on your own. Other abstraction packages were not meant for true portability but rather for interface makeup. I think you will be the better judge of that if you try looking at least at each package documentation. It is pointless to ask to people here when most of them only know one or the other package. You may also want to take a look at BinaryCloud which is a well designed and mature PHP application development framework. It works with Metabase and will save you countless hours of developing your applications from scratch.

Hi Manuel, I still don't see a problem in others telling their experiences with certain packages. If someone has just used metabase or has just used adodb then I would like to hear how easy/hard it was to port to another database. -Original Message- From: Manuel Lemos [mailto:[EMAIL PROTECTED]] Sent: April 18, 2002 9:37 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; Sp Subject: Re: [PHP-DB] Re: [PHP] Re: Cross DB application Hello, Sp wrote: Can someone with database expertise who has used metabase and adodb cut through this rhetoric and give an objective view of these two packages.

RE: [PHP-DB] Re: [PHP] Re: Cross DB application
There must be people on this list that have ported their web apps from different databases and could share their experiences. mysql - postesql mysql - ms sql server ms sql server - oracle -Original Message- From: John Lim [mailto:[EMAIL PROTECTED]] Sent: April 17, 2002 12:38 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: [PHP-DB] Re: [PHP] Re: Cross DB application Hi Manuel, Manuel Lemos [EMAIL PROTECTED] wrote Most of the popular database abstraction packages support prepared queries, except for your PHP ADODb. So, think about this before you keep throwing sand to the eyes of the users that do not know better, may be you understand the point of catching up on what everybody else is doing for a long time. If you read the ADOdb source, you would know it is untrue. We support prepared queries, and emulate them if the database does not support it. The reason for this is that you had the dumb idea to spam all the lists you could remember with the forged claim that ADODB was faster than every other database abstraction because your convinient benchmarks showed that. Tomas Cox rewrote PEAR DB after the benchmarks were published to speed it up. We even worked together to improve bits of PEAR DB. You just moan about how unfair the benchmarks are. Since your database abstraction could not beat others on real abstraction features you used that to drag users to your package to push them the commercial tool that you sell and requires ADODB to run. Visit http://php.weblogs.com/adodb-cool-applications for a long list of applications using adodb with multiple databases. None of the apps except the first link use our commercial product, phpLens. I think that pretty much refutes your statement. That was the lowest Microsoft-like marketing trick - trap them into your Windows clone database abstraction OS to sell them your tool for which you have no competitor because nobody else is doing anything like that for your own abstraction later. I interviewed to work at microsoft in 1989, but as a techie, i would have made microsoft bankrupt if they had let me run their marketing for them :-) Of course you may claim ADODB is faster than any other abstraction package, but that's because it does not abstract data type conversion to make user applications portable. Actually it does, but only for dates, because I find that most other types can be easily handled because PHP is a very good language. Char and varchar and numbers map easily to string and float/integer, and so forth. I have told you this before. It is the same as stating that driving a motocycle naked and without helmet you will drive faster than clothed with the helmet on. It is not the same thing, but unfortunately for the victim users that have fallen for your argument they did not notice that your abstraction can only be faster by doing less, meaning providing less portability support. Of course. Unneeded portability that is not used by most users is of no interest to me. You disagree. That is fine. The code is there for people to read. Let them judge for themselves. John, as a marketeer you still have a lot to learn before you realize that you can't fool everybody! Next you will release ADODB XP the one that makes hidden connections to your site to track what the users are doing! hehehe :-) Don't worry, nobody will sue you for the abusing the monopoly of applications for your PHP ADO DB! :-) Manuel Lemos Manuel, you might not believe me, but what you are saying will make people shy away from working with you in the future. Treating people with respect is more productive. I don't really want to spend my time defending myself when I can be doing something else. So I leave this thread to you and to you alone. The floor is yours. Keep it clean.
