siutable tool and technology for electronic health system?
<p>hello i am going to develop an EHR (Electronic Health Record System) i am new to this field and want to discuss and get the suggestion about what tool technology i have to use for this purpose: </p>

<p>here is my research about EHR and available tools for it</p>

<p>1) i am going to discuss about java as an EHR is a web based system so J2EE will be the solution for java at core level and as i am going to globalize my system so i need some standard protocol for it the most useful and appreciated one is <code>HL7 CDA 2.0</code> one thing about java i like is it provides <code>JAVA CAPS</code> with full implementation of HL7 protocol. it make my work bit easy the second thing about java is it is very efficient for <code>DATA CENTERED</code> application as mine one is but the problem is with the scalability of system that is much expensive and time taking. and java is bit slower on client side that can effect downtime that should me very less approaching to zero for my system. and at last i need a attractive user interface. and the most wanted thing is privacy and security.</p>

<p>2) the other option is <code>PHP</code>  for doing all as above described it is less expensive and less time taking for scalability,may contribute to achieve a good interface and a faster client side but question mark on data centric environment and security.</p>

<p>3) the last one is the MS's <code>ASP.NET</code> no doubt about security and privacy but very much expensive to develop and maintain and no platform independence and what about speed that is response and down times?</p>

<p>i have discussed the possibilities upto my best knowledge hope u people advise me which one will be the best to attain privacy, security, speed and scalability on best cost.</p>

<p>thanx in advance.    </p>
