I want to develop a Windows 8.1 app that uses a client-server model to send some data from the server to multiple clients through Wifi or within a network.
the functionality is similar to what's in this app http://apps.microsoft.com/windows/en-gb/app/67786fc8-b27b-4ea1-92f5-1ad8abfbeda1
would you please guide me to the APIs or concepts to use to achieve such functionality ?

I want to set up a MySQL instance to be accessible to a mobile app as a REST based API.
How do I make that API available on the internet?
One scenario I am considering is to install MySQL on a Linux instance within MS Azure and then I would generate the APIs using a tool like Dreamfactory.
Would that work or would I need to install the MySQL DB on an Apache web server to make the API available?
Additionally - do I need to be on a domain to do this? So I will have to pay for a domain and hosting too?
What kind of server and software would it be necessary to create an app (Android/iOS) that could make requests to a server, which would run a machine learning algorithm on each request while using data/images stored in a database(MySQL?) ?
That is to say, the user would send some data to the server, which would run some machine learning algorithm on this data and some other data obtained from a database, and then send a response to the user.
The algorithm on the server should run in some language like C/C++, and use some library like or software like OpenBR.
PS: could something like Microsoft Azure or Amazon web services be useful?
You could use Google App Engine for running machine learning algorithm and use that as a backend to your mobile application. You can use this tutorial on how to do this.
I am trying to make a Data Monitoring with Mobile App.
I have a mysql database and i am planning use Node.js server.
My project:
Node.js server connect to mysql db.
Mobile apps connect to node.js server and when the new data add to mysql, node.js server send to data mobile apps using restful service.
Is it possible to communicate between node.js server and firemonkey mobile client apps? (I' ll build mobile apps via firemonkey - Delphi)
The reason to use push notifications, is so that your Mobile app does not waste resources to maintain constant connection to the server awaiting for new data, whether it is a web socket or a check for new data.
Keep in mind that Push notifications code might be different for Android and iOS platforms.
I'm attempting to write a Windows Phone 7 application which needs to connect to a remote data source, in this case it's a MySQL database on a Linux server. I'm not able to move this over to MSSQL, nor to build any kind of windows-based solution (like a WCF web service on the server).
Is there a way for me to use my MySQL database from my Windows Phone 7 application? The MySQL assemblies don't seem to work on the phone. If not, what would the best solution for me to use this database from the phone?
You could build your self a service which would send you json or xml. this can easily be built using mono, python, Ruby, php or any technology that you are comfortable with.
You can build it in a restful manner where all you have to do is call urls in a HTTP GET to retreive data which you handle with the services.
and use the HTTP POST to submit changes to your service.
you can then from WP7 make calls to this service and consume the data.
WP7 does not support sockets at the moment. So your best bet is transfering your payloads over HTTP.
As I mentioned before, if you have access to the machines configuration. You could run Mono which isn't too far off of .Net in terms of language and functionality.
further more, from the phone you can use the Rx library to make these calls Async and keep your application responsive.
I do a mobile application which the user can use it get the required place’s number. The user must select the appropriate city and category to get the place’s information. All the information stored in the database.
What I want to know that ..
1) What is the benefit from the web service?
2) How to connect the web service and MySQl database?
3) How to connect the web service and mobile application to get the information from the database?
1) Benefits. You didn't mentioned other options, but if you are talking about some custom server-side implementation, the benefits are numerous:
It's easy to connect to web service from J2ME.
Multiple connection sessions at one time.
You can use web service from different applications and different technologies.
No issues with authentication and authorization.
You just call method from ws and in response you get easy-to-parse XML.
2) Web service - MySQL:
You have to create a Tomcat or IIS web service.
From web service code connect to MySQL, call a query and return the result.
For Tomcat and Java web service:
Getting started with Web Services Using Apache Axis
Developing and Deploying Java Web Services with MySQL on Apache Tomcat and Axis on Windows
JDBC for MySQL
For IIS and C#/.NET web service:

3) J2ME - web service (with JAX-RPC)
1. generate stub from web service WDDL using J2ME Wireless Toolkit
2. add stub to your project, import stub namespace, set connection properties and call stub methods
