Tony: I always think of the costs for PDP to be similar to that of wIntegrate. You buy a database license and a connection license (like wIntegrate) for the client end.
If you build the application as a windows app then you pay like wIntegrate (25 users = 25 U2 licenses + 25 PDP.NET licenses). If, however, you build an ASP.NET application then you pay less (25 users = 5 U2 licenses + 5 PDP.NET licenses) because the dbms license is only consumed when used and connections are shared. This is strictly an internal 25 user analysis. FlashConnect, in a non-persistent mode, costs $1,500 but you don't pay any connection licenses (25 users = 5 D3 licenses + 0 FlashConnect licenses). In addition, the purchased Flashconnect component resides on the Web server. Although a dbms "account" is installed on each D3 dbms server, it's the web-server component that is paid for. FlashConnect can be installed on multiple D3 dbms servers with no additional costs (except for dbms licenses, if required). Redback costs $4,000, which includes a $1,000 Redback server and two webshares (connection licenses) at $1,500 each. In a non-persistent mode the two webshares can probably handle 25 users = 5 U2 licenses + 2 Webshares). I believe each webshare takes a single U2 license. Each U2 server needs to purchase the RBO server and webshares. I could be wrong about how many webshares are needed. All reports I've heard say webshares work very efficiently. In addition, there is an enterprise pricing model available for high-load sites. Anyway, these are three distince pricing models and all represent different approaches to "webizing" an MV application. FlashConnect is more of a BASIC oriented approach but it doesn't work for U2. Coyote Web (not previously mentioned) is very similar to FlashConnect and does work for both U2 and D3 (maybe jBase too). So if someone is looking for an MV BASIC solution they would do well to use FlashConnect for D3 or Coyote for U2. Redback is a stable solution that allows for standard web development with connectivity to a U2 database. It is much more costly than FlashConnect if the data is distributed amoung several dbms servers. PDP.NET is a new product but allows development via the standard Visual Studio .NET IDE with connectivity to a U2 or D3 database using the .NET toolset. You can write the code in .NET or in MV (as can be done with Redback). Just a few additional notes. :-) Bill > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Tony Gravagno > Sent: Friday, May 21, 2004 4:32 PM > To: [EMAIL PROTECTED] > Subject: RE: [U2] UniVerse in VB .NET > > Colin Alfke wrote: > > We did (somewhat) investigate the pdp.net route but cost > > considerations precluded it for us. > [snipped] > The pricing is actually pretty good whether using persistent > connections, or especially for non-persistent apps which > are permitted per recent RD marketing.
