What I mean

Post #61,136 by drewk 11/5/02 8:50:25 AM Reply	What I mean We use PHP. I have no problem admitting that the development environment for ASP is much richer than that for PHP. All of our database interaction, for instance, has to be done manually. We've created classes to abstract the nitty-gritty, but we still have to interact with it at a fairly low level. Granted, one of the problems with ASP is that it encourages people to not bother understanding what they're doing. But the promise that you shouldn't need to know that is the goal. So for now instead of having to type five lines of code every time we want to query a database, we only have to type three. Sure, there's better error handling and reporting, and we've got some convenience and debugging features built in. But we all know the DB abstraction class could be improved. But until we have time to re-write every single page that touches the existing class, it's a non-starter. We've discussed versioning, but the code is bloated enough without introducing our own layer of class-version hell. === Microsoft offers them the one thing most business people will pay any price for - the ability to say "we had no choice - everyone's doing it that way." -- [link\|http://z.iwethey.org/forums/render/content/show?contentid=38978\|Andrew Grygus]

I am not sure where the bottleneck is in your simplification attempt.\r\n \r\nI take that back. I think you need two different handles minimum for PHP (assuming MySQL API). I'll have to experiment to verify that.\r\n ________________\r\noop.ismad.com Edited by tablizer Nov. 7, 2002, 03:21:05 AM EST Expand All History

For pages that deal exclusively with one database we can set up the single connection and re-use it. I know you don't like OO,, but that's how we write our PHP. Since we're using OO programming to interface with an RDBMS, there is an "impedance mismatch". If we had an object/relational database, we could define the objects in the DB and query things much more naturally. So instead of $db = new objDB( "db_server_1" );\n$sql = "SELECT \n tbl_user.*,\n tbl_office.addr1 AS office_addr1,\n tbl_office.addr2 AS office_addr2,\n tbl_office.city AS office_city,\n tbl_office.state AS office_state,\n tbl_office.zip AS office_zip,\n tbl_office.phone AS office_phone,\n tbl_office.fax AS office_fax\nFROM\n db_user.tbl_user,\n db_office.tbl_office\nWHERE\n tbl_user.office_id = tbl_office.id\n AND tbl_user.id = '$user_id'";\n$db->query( $sql ) we could use $db = new objDB();\n$db->query( "GET user '$id'") That's what I mean by "manually". === Microsoft offers them the one thing most business people will pay any price for - the ability to say "we had no choice - everyone's doing it that way." -- [link\|http://z.iwethey.org/forums/render/content/show?contentid=38978\|Andrew Grygus]

If we had an object/relational database, we could define the objects in the DB and query things much more naturally. Since you don't have an ORDB nor an OODB, perhaps it would make sense to stop trying. IOW, give up on OO so that you are not constantly battling paradigm translation/adaption issues. I suppose your response is that OO is so useful that the translation costs are still worth it. Is OO really that much more useful in your mind that you are willing to spend such translation/adapting costs to have OO? I won't fuss if you say, "yes", I just want to confirm if this is your reasoning for pursuing it despite an admitted translation tax. ________________ oop.ismad.com
