Re: Architecture Question - Opinion

Hi, thank u for this interesting discussion. SQL Relay seems to be an interesting tool. It offers a variety of features often missed in PHP. Especially the connection pooling technique promises an performance advantage, cause it reduces the typical overhead of database-auth on every script run. I´m just implementing a kind of application server with PHP. There is a PHP-clientscript residing on apache webserver that does RPCs to a server-deamon (written in PHP with PEARs Net_Server) and then generates HTML-output. The server handles business-logic, persistence of objects and does some caching. Like u Paul, i have now the same Problem: Using XML-RPC or SOAP. Look at http://weblog.masukomi.org/writings/xml-rpc_vs_soap.htm . there is a simple guide comparing both. I will first make use of XML-RPC. It´s quite simply and has a short learning curve. If i need more flexibility later then i will use SOAP and update my server/client-classes. greets Jan "Paul Miller" <pmiller@system-wise.com> schrieb im Newsbeitrag news:IOEMKBGHKENDMKOBIGKCAEKECBAA.pmiller@system-wise.com... > All, > > I originally sent this to the DB list, but I want to hear anyone's opinion > here. > > I am considering moving to a true 3-tier structure where the web server > does not have direct access to the database server - many times a government > requirement.
