Hi,
   
  Sorry i missed the number of lines of code, just over 488,000 in OpenROAD.
   
  I have no idea if the 36 months is man days or not.
   
  Thanks for the replies so far.
   
  Frank.

    Hi Frank,
  sorry I dont have more time just now to give a decent reply...
   
   
   
  3. XXXXXXX (a company working with Ingres) has developed tools for code analysis and migration to OpenRoad Applications Server which    
  There are also companies out there offering manual conversion services to OpenROAD Appserver. I believe the costs are be comparable. Feel free to shop around... 
   
    It is a "thick client", requiring software delivery to PC's,    
  OpenROAD can be deployed as thick or as thin as you wish. from:all business logic is managed by the appserver, to: eclient is used deploy fat client, to: standalone machine with local DB.
   
  it is vendor specific and not standards based,    
  Oh dear. Please send your client to ingres.com to see the presentations at http://www.ingres.com/customers/vip-archive.php 
  Some good ones are 
  "Hello World! Taking Ingres Data to the Web"
  "Hello OpenROAD! An Introduction to Rapid Application Development for Ingres"
    "putting the open into openroad"
   

  
  also the developer skills base is in decline.   
  Dont you just love blantant inaccuracies? I personally have trained 2 new developers in OpenROAD in the last 12 months and have been involved with 2 new installations. PeerlessIT opened a shop overseas in the last few years and has hired/trained over 10 new developers (I've lost count) Myworkplace (business partner) has trained 3 new developers in the last 3 months. In the last 2 months there have been 16 new subscriptions (however 13 unsubs because I was doing a bit of cleanup). Generally I have seen increased activity in OpenROAD in the last 12 months. 
   


      using the Ingres product would also involve third party consultancy and additional licensing costs, 
   
  We use OpenROAD to talk directly to all sorts of technologies, it costs only development time. Here are some integration projects I've had to deal with for just one client for example:
  XML data feeds, HTTP post to internal and external services, link to .net assembly, call modules written in c# to deal with proprietary protocols, calls to VB6 and VB.net modules,  standard calls to windows DLLs, write and deploy our own creditcard encryption DLL. Also external calls to most microsoft apps, embed activeX components in the application, updates to Oracle, MSsql, MSaccess, Ingres, and even a lantastic based database in a single logical transaction .  Peerless integration applications are used in banking/finance, internet gambling, data streams from serial port, monitoring PLCs in manufacturing, laptops installed in trucks printing invoices for clients and monitoring fuel usage. 
  None of these integrations functions carried licencing overhead.
   
    6. A detailed analysis of the XXX client code is a pre requisite for re writing the application, 
   
  You'll be doing this in anycase. Dont be under the mistaken belief that moving to appserver is simple cut and paste. There is a fundamental paradigm shift. Some business processes are not suited to thin client technology. Long running transactions and batch processing need special attention. The same questions will arise no matter what the language. 

    4. The use of the XXX OpenRoad client will be run down over time, with its business logic processing being moved to the 
   
  One of the benefits of Appserver is you can migrate screens, functions or whole modules at a time without putting existing application functions at risk.
   

    6. Greater responsiveness to business change requirements – a business area can be updated without a complete application upgrade. More functional releases possible in shorter timeframes, and reduced development and operating costs. 
   
  My experience with VB.net development has been more expensive than OpenROAD. I have 2 openroad developers keeping up with a team of 5/6 web developers.  To release a web service based on VB.net requires taking down all business functions on the website. (in the case of load balanced servers we take them down one by one then turn on a soft switch) With OpenROAD fat client we just put a new image onto the shared file server. Existing sessions are not affected. 
   
  
  Our current application has lines of code, rewriting in Weblogic/Java/.net is expected to take 36 months.   
  How many lines? Is that 36 man months?
