How can I establish connection of a Flash site with a database(i.e. MYSQLetc)?
If you need to pass the Data from Flash to Database , for example Registration information , then follow the Tutorial
I assume you have knwoledge of Server Side Scripting like PHP or C#
I had to do this for a college project I did before and you can easily do it with the URLLoader and URLVariables functions by stocking up your variables and sending them to a page or recieving the variables and then taking them out of the URLVariables function.
However if you were to be passing arrays or dynamically chosen variables then you would need to pass all of your data as a comma seperated string and then parse through it on the other side and vice versa.
I'll try to post some actual code when I get home but I hope this helped
You cannot connect to a database server directly from flash.
To communicate with the database you need a webservice.
There is a project called assql that connects Flash directly to the database but is aimed at AIR projects. AMFPHP is good for using php to save to the database from AS3.

I would like to know if this scenario would be possible in any programming language combined with any database technology.
I would like to automatically save received pdf files that are attached in emails into a database. Is this possible? Is there any library or framework available to do so?
Yes, I would recommend using Google Apps Script for this. The approach you should follow is to use the GmailApp class (Documentation here) to get the messages you need, you can use methods like getInboxThreads() (Documentation), to retrieve the messages.
After you've found the message and retrieved the attachment (which you can do withgetAttachments() (Documentation)), you can use the JDBC Service to connect with external databases. The specifics here depend a lot on what database you want to connect with, but the documentation will lead you in the right direction.
I want to make an app as my final project for my teacher. I will have images of homework assignments and the date of homework assigned in text format in the server. And I want to make an app where it will access it and put it in an activity.
So I need to know what kind of server do I need, if I could just use google drive somehow or not?
Save it as JSON, you save the images on your database and call it in your JSON.
But for what you intend to do I think FireBase will work just file because it is free for small projects like this.
I really can't think of a scenario that would make me use ngcsv, it converts array to CSV file.
What I don't understand is why the server couldn't just return a proper file instead of pass the data through client code first. If you use I'll be happy to understand why this is useful.
Presumably it would work without access to the server since the code is all completely client side.
I'm planning on using it in a 100% offline app that relays on LocalStorage.. so I guess there's many scenarios where it could be useful
I want to create a a application in actionscipt 3.0 that allows the user to listen to music and read descriptions of the music. For this to happen i suppose there should be a database where the textbits and music is located and then flash fetch the info when the correct buttons are pushed. The database will contain up to 100 tracks and textbits.
The application will function on a stand that won't have a connection to the internet.
What is the easiest way to do this in actionscript 3.0?
If any of you are familiar with UML and thinks this might help in understanding the problem, then here is use-case and flow-chart:

Thanks in advance.
The easiest way to do what you're asking is probably to store the files in a directory on the machine the application is going to be running on, and then design an XML structure for storing your data. The XML is easily loaded in to Flash at runtime and is easily edittable.
Your other option would be running a database server on the machine, creating web services that run locally and push/pull the data from the database, and then call those services from your Flash application.
The first option is most definitely the easiest and should be able to provide exactly what you need. The second would be more geared towards a distributed Flash application where you needed a central data repository for the clients.
If you're building an AIR application, you can use the integrated SQLITE database. But, i agree with Justin, the easiest way is to use a XML file.
You can probably consider using "Local Shared Objects" which is a kind of cookie, with bigger capacity (100Kb by default, but you can change it). Compared to other solutions already proposed, it has then advantage of not requiring any web server.
How would one create a REST web service to write a row into a databse table. Use the follwoing scenario:
The table is called Customer - the
data to be inserted into the row would
be the name, addresss, telephone
number, email.
I think its impossible to describe the whole thing end to end in Java or C#, and I would never expect that, but here are the questions I have popping into my head as I prepare for coding:
How the URI would look (eg. if you use this URL - http://www.example.com/)?
What info would go into the HTTP envelope?
Would I use POST when writing to the database in this way?
Do I use a resource to store the posted data from the client? Is this even necessary if the data is being written to a database anyway?
When the data to be writeen into the db is recieved by the server - how do I physically insert it into the database - do I call some method on the server to actually write the data (in Java)? - this doesn't seem to fit with truely REST architecture - shunning RPC calls.
Should I even be bothering writing to a DB - should I be storing my data as a resource?
As you can see I need a few issues clearing in my head. Any help much appreciated.
First of all, I'm not either java nor c# expert and I don't exactly know what means do these languages have to support REST design, but in general:
http://www.example.com/customers - customers is a collection of resources and you want to add a new resource to this collection
It depends on various things - you should probably set the content-type header (according to the data format in which you are sending the representation) and set some authentication headers if you need it.
Yes, you always use POST to create a new entry in a collection of resources.
I don't fully understand this question, to be honest. What do you mean by "inmediately writing data into the database"?
REST is primarily just a style of communication between server and a client. It doesn't say anything about how you should handle the data received by using it. The usual way how modern web approaches (MVC style frameworks) solve it, is by routing every REST action to a method of some class (usually a controller instance) where you handle the received parameters (eg. save them to the database) and generate a response to be sent back.
For a very brief and very clear introduction to REST have a look at this short video.
RESTful Web Services, published by O'Reilly and Associates, seems to fit the bill you're looking for.
As far as doing it in Java, Sun has a page on it.
