Hi World,

Can anyone point me to any rescources about interfacing and
iPad/iPhone to a Universe/Unidata database?

Any help would be fantastic!!

Thanks Kevin

If I could be more specific I would...

I program interfaces to Universe in VB6, VB.NET, SB+ and a bit of web
interface work.

What I would like to do is natively log into a Universe database,
execute a query and return data to an iPad application.

I am just starting to learn xCode and the iPad environment and toolset
so am not completely up to date with the xCode terminology or exactly
what I am asking for.

Cheers,
Dean

I'm not familiar with the interfaces available to Universe, but I
doubt they have a native library for iPhone/iPad. You'll probably
have to go the route of a web service, or some other intermediary
technology.

If you like Basic, you might want to check out http://objective-basic.com
for Apple platforms. It's fairly new, so not 100% feature complete,
but it's pretty good. It actually converts basic syntax to objective-
c, so there's no vendor lock-in. It does not yet support iPad/iPhone,
but still worth a look if you're interested on OSX programming.

This is another "can I connect MV to 'foo'?" FAQ.
Of course. You can connect anything to any MV system.

Dean, search my blog three times for terms:
iphone
pda gui
mv to anything

To summarize my blogs on the topic: You're not connecting iPad to
Universe, or iPhone to Unidata, or your coffee pot to D3 (though I
actually have done the latter). You connect to a middle tier and then
connect from there to your data.

When you're on a web page does anyone here think their browser is
connecting into MySQL? It doesn't. You're connecting to a web server
using the HTTP protocol. The web server then gets data from a mySQL
database, or whatever data source it requires, usually on a different
server. Increasingly web servers are doing mashups where data is
aggregated from multiple remote servers through web services. and
presented in a page to the user's browser. One of those data sources
can be your MV app.

Devices like iPhone, iPad, and Windows Mobile are client
environements. They don't do data retrieval. They make requests to
remote servers, usually via web services. These servers then
aggregate and return data, and the device just renders it.

The process is exactly the same for anyone doing Flash/Flex or
Silverlight. You request data from a server, that server requests
data from a data source, and the result is passed up the line.

What does this mean in terms of languages? You need a different
language/technology for each target.
For the client tier:
- For iPhone and iPad it's Objective C.
- For Silverlight it's C# or VB.NET.
- For RIA web pages it's JavaScript.
- For Flash/Flex it's JavaScript and XML.
For the middle tier:
- Anything supported by the server including PHP, Ruby, C#, VB.NET,
Java, Perl, C++ ... this is completely independent of the client, and
this is where people get confused.
For connectivity to the MV database, take your pick:
- mv.NET
- UO.NET
- UOJ
- jRCS
- QMClient
- JD3
- ODBC/JDBC
- D3 Class Library
- FlashCONNECT
- sockets, telnet
.... again this is your call, and with the exception of mv.NET is
largely dependent on your MV platform.

The bottom line, again, is that you're not going from X to Y, you're
going from X to Y to Z. Z is your database. X can be anything. And
once you decide what you like for Y, you can connect any X to your Z
and never have to worry about how to do this stuff again.
