I am trying to create an integrated project in which I can update MS-SQL's database value using J2ME's application.
But I need more resources/links that let me fully understand how to go about writing implementation for this.
These are the few question in which I've got in mind.
How do I update the data that I've got from J2ME into MSSQL 2005?
How do I retrieve and view the updated value from the database?
How do I send sms to the J2ME's application, as the other application of mine need to send an 'alert' to the j2me app.
Short of writing your own ODBC library for J2ME, I would suggest you look at writing a web service layer over your database which the J2ME application can communicate with over HTTP.

I want to building an android app by Xamarin, C# language. This app can get or insert data to MySQL, this SQL hosted on another PC
So, Where I can get information and tutorial for this?
Thank you!
Basically if your MySQL database is in another computer, you need to communicate to it over web, I would suggest you use API, in computer with database make API Application.
https://learn.microsoft.com/en-us/aspnet/core/web-api/?view=aspnetcore-5.0
There is microsoft documentation for it.
Create endpoints for specific actions, and then communicate with them from your Xamarin App, here's the documentation: https://learn.microsoft.com/en-us/aspnet/web-api/overview/advanced/calling-a-web-api-from-a-net-client
Create API service on computer with database
Communicate from your application to API (then API communicates with database, and sends back results to your Xamarin App)
I personally like RESTful principles for API's. documentation: https://restfulapi.net/
You should also consider adding authentication to API, so that only apps you want, can GET/INSERT data to your database
to get data from mysql in any app you need to API:
i using ASP webservice to get data from mysql
then in Xamarin.Android APP in refrence folder click right and add web refrence .

I'm looking to start a small application for maintenance techs to view production status of lines and whether they are running or currently throwing an error.
Essentially when a user keys in that the line is experiencing problems it will pass a value to the DB we have. The IOS app should be able to read the data from the table as to take it and then create visual warnings for techs to access view through the app. An example of this would be a small Green/Red Square representing the current status of a line
Does Xamarin.IOS support this via an ODBC connection? I have done some preliminary searches for accessing the data through a web server but I am not quite how this would be implemented.
Any help would be appreciated - Cheers,
It is better if you can write a separate backend server application to deal with DB. Expose that server through the Restful Web API and then access that Web API from the Mobile app. If you are planning to use an in-app local database, then you can write DB service with SQLite. Refer below link

I am building an application that needs to connect to a server to send and retrieve data constantly.
at first i was going to use mysql, by mysql is far from what i want. using this would force users to connect to the database constantly.
CAN C# silverlight connect to a server and send a message?
here is an example to something in C# console, VERY similar to what i am trying to achieve
https://www.youtube.com/watch?v=9kcrTKj7Jpk
Any documentation would also be helpful.
To be more specific my server will be written with C# console, but i want my c# silverlight to send the message.
Yes.
CAN C# silverlight connect to a server and send a message?
Traditionally, the way that Silverlight has connected to a server to send a message is with WCF services. This still works well, but the other option is REST.
What you will need to do is write a layer (or use an ORM like Entity Framework) to persist data from whichever database platform you choose (MySQL or otherwise). Then you will need to write REST, or WCF services on top of this. You will then need to consume the services from your Silverlight application.
There are many articles on this if you Google. Here is one of the ones that comes up instantly:

One thing you must consider with Silverlight, is that by default, Silverlight will only talk to the server that the Xap package is hosted on. So, if you need the Silverlight app to talk to a different server, you will need to set up and expose a clientaccesspolixy.xml from the server where the WCF/REST services are hosted. This is a stupid limitation that Microsoft made a big mistake on in the first place. Here is an article about it:

I am struggling to figure out how to connect to a MySql database in my C# Windows Phone 8 application like I can on my desktop application. The reason I am struggling is because it seems I cannot just use the same MySql.Data library that I used on my desktop application. Are there any other libraries that I can use to access my database?
PS. I really don't want to go the PHP route because I will have to have Apache running on y server two and will have to add JSON interfacing two which will not only be a hassle but possibly also waste some processing time and make my application more complex.
PPS. If not possible with MySql, can it be made to work with Microsoft SQL Server or Azure?
EDIT:
If some sort of HTTP interface is my only option, is there some easy existing API or something that I can use to allow SQL data transmission or will I have to create specific PHP(/asp.net or whatever) code for each type request that I am planning to send?
I have a pre-existing desktop application that draws its information from a Microsoft SQL Server. The desktop application is written in C#/ASP/.NET.
I'd like to take this same data and present it in an iPhone application. What would be the best way to obtain and present the data?
I would recommend writing a web service that exposes the data and then interfacing with this from the iPhone across the network.
Calling web services and making HTTP calls is very easy on the iPhone.
Do you assume your iPhone application will have network access? If so I would go the webservice route as already mentioned. If it's a small database that you want available on the iPhone with out the need to access the internet to retrieve data you could look at converting the SQL Server database into a SQLite database and packaging it with your app.
