OrientDB embedding mobile - licensing

I am working on a pet project mobile app. I am planning to use OrientDB in embedded mode with the app. Here are the questions i have:
Am i free to use OrientDB embedded in a mobile application? This application will be distributed for free to users on Android playstore.
Can the embedded OrientDB synchronise with Baasbox. At this point in time, the synchronization is only one; from mobile to the api server.
Please let me know. I am a noob with Graph databases in general.

To answer to your questions:
Absolutely, OrientDB Community Edition is FREE for any usage (Apache2 License).
There is no off-line synchronization in OrientDB, so unless BaasBox implemented it, it's all up to you.


How to make a cloud and all platforms offline apps together?

I know is hard to develop web application and make a individual app versions in each device.
But i just want to know how that works with big companies.I want to know how they write there code
The best example is Evernote and Google Drive.
They make a cloud application and individual apps for each device.
So the questions are..
How do sync the data with the cloud apps ?
Do they use version control ?
Can i get software requirement specification anywhere ?
Platforms and Languages:
iPhone and Mac - Objective C
Android and Other Mobile Apps - Java
Windows 8 - C#
Web Apps - PHP or Python
How do you solve this solution languages differ?
I guess i it's not possible with version control..
How to minimize coding ?
I recommend you use a version control tool.
make a individual app versions in each device.
I assume you mean developing different versions with few differences. The branch feature in a version tool can help you manage these versions easily.
How do sync the data with the cloud apps ?
You can use the web deployment feature to upload the applications/modifications to your web server.
I list some version control tools here for your reference:
SourceAnywhere (I work for the company)
Team Foundation Server

Is silverlight the right choice of technology for enterprise applications after Microsoft's comments in PDC 2010

We were beginning to start on an enterprise application using silverlight.
However after reading this post we doubt whether it is the right choice going forward.
The post says that, according to
Microsoft's declaration in PDC 2010,
Microsoft has changed their strategy
regarding silverlight and they no
longer view it as their technology to
deliver cross platform applications.
Instead they are targeting silverlight
as their development platform for
Windows phone 7.
Is this correct? Should we still continue with silverlight or go back to ASP.NET WebForms\MVC?
The Scope of the application is basically intranet with Windows 2008 servers and Windows XP and Windows 7 clients. However a subset of functionality needs to be available to the external users over the internet. There we cannot have any restrictions on what OS users can use.
based on the info you gave, I can't conclude whether silverlight is the way to go. But what I do know is that a number of Microsofties wrote some blogposts about the things said about Silverlight on the pdc. For example John Papa, Bob Muglia and Scott Guthrie.
Update about the scope
I think you already gave the answer when you described the scope of the application. A part of the application will be available to external users and you cannot have any restriction about the OS they are running. With that requirement I think Silverlight is not the best way to go. Not because the rumours about its future but because of its platform indepency. What are the reasons not to go for a ASP.NET/web solution? Silverlight doesn't work on each OS whereas plain HTML will work everywhere. (ok you need a descent browser)
Although for a good advice I'd need more information about the application.
Basically the question you have to ask yourself is this: do you need your application to be used on every platform, i.e. Windows, Mac, Linux, misc. flavors of Unix, IPhone and other mobile platforms?
If that's the case, then a web based solution is the way to go.
If Windows, Mac and partially Linux is enough, then save yourself and your team a lot of pain and use Silverlight.
In my opinion support for mobile clients is the key factor in your decision.
For sure the right platform for Intranet, Enterprice applications Is Silverlight. It is
stable, performs extreamly well, the environment and the development time is huuge less than web application development, the end User Experience is much better and so on and so forth... Once you want to show part of the system out the the intranet - just create some specific target modules that will address the needed audince. You won't have the universal "Reachfull" solution, that will target everyhing, you'll always need mobile versions or other devices and so on. But once you've built your project the right way with Services (same services that the Silverlight app will consume), it'll be easy job to consume them with new UI.
Hope you will choose Silverlihgt.
Silverlight is a great technology, but the Microsoft does not develop it anymore. So as a technology is a great decision. But if you want to make a Silverlight app usable on a NOT supported platform (e.g. Android or iPhone) you have to use 3rd party services. For example http://sl2html.com

How can I write apps for the latest Sony Ericsson phones?

For me in particular it's about Sony Ericsson W715.
What languages can I use and what environment do I need?
A tutorial recommendation would also be nice.
Well, without more information as to what your applications are supposed to do, I would also recommend J2ME, especially given that SonyEricsson has additional useful proprietary APIs that are available to their partners.
You can also target the web browser on the phone by having a server send dynamic HTML and javascript code.
Flash Lite is also an option.
Recent SonyEricsson phones contain the capuchin technology: Write the GUI in Flash and the application engine in J2ME. That could be worth a look, depending on the skills of whoever is working on your applications.
They have a developer page..
Your only option would be J2ME. I recommend using Netbeans with the Mobility Pack for the task. Download the Java version, that includes Java ME.
Here is a tutorial on the net. I am sure you can find many more.
You should use J2ME (Java Micro Edition).

A database system for storing mobile device data?

I'm starting to build an app, a mobile device. Performance is quite important (as it is in anything else) and I'd like to maximize it.
The database will be used pretty often. I'm looking to access it through the QtSQL library of the C++ Qt library.
I have experience in MySQL, but don't think that's the right choice.
So I'm looking at:
The operating system is a stripped-down build of Ubuntu. Need regular CRUD as well as opportunity for optimization.
Since Apple uses sqlite on the iPhone and iPod Touch, I would take a good look at that. I assume that they will have evaluated everything available to them at the time to get to this conclusion.
Since sqlite is FOSS and "endorsed" by a well-known vendor of mobile devices, give it a try.
Did you consider Sybase Ultralite?
I'm a new student developer, but it appears that SQLite might be the best bet to go. Aside from being what seems to be the preferred iOS online database... it seems to have a lot of support with Android and the upcoming [Windows Phone 7 Platform][2] (via C-sharp-sqllite). Which seem to be the most dominating (or in the case of Windows Phone 7 - upcoming) platforms for most web development. Blackberry and webOS doesn't seem to have an issue either.

Using KLone for web development

Would anyone be kind enough to share about your experience using KLone in a web project? Mostly, in what context are you using it?
Their home page mentions that:
KLone is a fully-featured, multiplatform, web application development framework, targeted especially for embedded systems and appliances.
However, to what extent if any is it useful for general purpose web dev?
