flex value objects with database - actionscript-3

I know this question is vague, but I have a school project, which works with HttpServices that call to PHP-files to insert and retrieve data from a database. Now the teacher told me I have to work with valueObjects to work with the database, but I haven't received any further information. I can't figure out what to do...

I have a good sample app and tutorial for using Flex and PHP for database connectivity using valueObjects and zend-amf as the server on my blog, which should be a good starting (and maybe finishing point). The example has View Source enabled, and I have included all the php files that were used. I expect a good +1 for this:-)

You should find a lot of information in the Flex In a Week video series on Adobe TV.
Probably the answer to all your questions and more.

updating the content of another webpage

I am a beginner web developer and working on a school project. My apologies for asking this basic question.
I am trying to create an online shopping store. What I am trying to do is when the user clicks on the checkout button, the shopping cart page gets updated with that element.
I don't know how to accomplish that. I really appreciate if someone can point me to a tutorial or provides some tips.
Your question is really abstract, however you will have to find the right way to communicate with a database...it might be php/MySQL with laravel or some other framework or preferably C# asp.net with entity framework(that's what I will go with its not mandatory some people like php) Then you need to learn some lambda or sql depending on which approach you would like to take (php/C#). You will probably need to get some kind of grid control for the cart asp.net has default one personally I find it confusing and hard to work with( there are many controls that can be downloaded freely without charge for non commercial products search google) then you would need to fill that grid with the List of objects that you will get from your database. If you get that far alone the next steps would be easy you will probably need some javascript for ajax calls to a webservice or either your backend so you can submit the orders. For the right tutorial there is none actually since your question covers several topics regarding database modeling, data fetching, backend development and front end development. You can start by getting yourself some kind of server (look for mssql for asp.net) and MySQL for php, then you should look for some kind of database modeling tutorial basic tables relationships 1-1 1-* *-1, after that you would need to do your design (from the question I assume that you already have one downloaded). Then if you got down to this step you should google the way for the right way of communicating with your database from the backend of your website (I advise entity framework its clean and easy) you can generally bind the list of objects directly do the grid that would represent your cart (I say grid but you can give it data template to look like html, not to be confused with regular tables). If you really get here I see no reason to keep coding for a school project in most places you can use all this to bachelor degree exam and pass with straight A. But if you want more details look into these videos they explain quite well what you want to do.

I am not great at JavaScript but I think your page would need to update a cookie then read that value from said cookie. I hope that's a good place to start!

database recommendation for an offline html cookbook

I am currently planning to transfer my cooking recipies from a word document into an offline webpage. I have a (very) basic understanding of html, css and javascript, but never really got in contact with a database.
Can you recommend any database that I can use for my project?
My requirements are:
ideally future-proof -> widespread usage, state of the art and exportable for future use
broad applicability (maybe useable in future projects), not just for cooking books
no php, since the page is offline a server should no be necessary
no need for a fancy user interface. I would prefer to just enter and change the data directly in the database, like entering text in excel. I do not want to use commands like "update" or "insert" to add data.
I read about Excel, MS-Access, mySQL, MariaDB, …
Can anyone recommend a database for my purpose? This would really help me out! I am lost in the jungle of opportunities.
Thank you in advance
Best regards

Edit: I uploaded an image to clarify my idea. Unfortunatly stackoverflow does not allow me to embed it into the post, thats why I only posted the link

One of the tenets of Rails is you shouldn't really care what database you're using: that's all abstracted for you. I know it's kind of diverging from your skillset, but Rails would be a great approach for an application like this, especially if you want to deploy to a server instead of running it locally down the road.

how to get started with a project

I have to write a program that tests products fully automatic.
I still don't have the finished prototype board but i have an development board for the I.MX6UL processor
see picture below
http://www.nxp.com/products/sensors/gyroscopes/i.mx6ultralite-evaluation-kit:MCIMX6UL-EVK?
My first task is to put an uboot and linux file system on the board trought TCL code => asked by customer.
This all have to be done trough a usb connection that is connected to the development kit board.
NXP provide some tools that is called MFGTOOL2 => with this i can install a fully working linux but ofcourse i need to do this with code scripting and not via a tool because it's for production testing.
All this has to be installed on an nand flash ?
Your question is very vague and likely to not be useful to others as so much of it looks specific to your development environment. This means that the first step is going to be for you to do some research so that you can learn how to split the project up into smaller tasks that are more easily achievable. One of the key things is likely to be identifying a mechanism — any mechanism — for achieving what you want in terms of communication (and enumerating exactly what are the things that will be communicating!) Once you know what program to run, API to call or message to send, you can then think “How do I do that in Tcl?” but until you are clear what you are trying to do, you won't get good answers from anyone else. Indeed, right now your question is so vague that we could answer “write some programs” and have that be a precisely correct (but unhelpful) reply to you.
You might want to start by identifying in your head whether the program will be running on the board, or on the system that is connected to the board, or on a system that is remote from both of those and that will be doing more complex management from afar.

How do I extend this Netbeans JSF2 CRUD example to have a single create and edit form for all entities?

I recently discovered this very useful Netbeans tutorial for creating a simple JSF 2 CRUD application http://netbeans.org/kb/docs/web/jsf20-crud.html. The final product has somewhat limited usability as one is confronted with a myriad of web pages. I would like an example of how to consolidate the Create and Edit forms (using the same project if possible). This seems more in keeping with how a person would actually enter such information and would reduce the risk of data entry mistakes. Why enter a client and their billing address on separate screens? One should be able to add or remove addresses, if need be, on the client's edit form. Or if a new client has multiple addresses, enter them all on the client's create form. The application just seemed incomplete with no further tips on how to improve it. If one has knows of a useful book that covers this, then I would gladly read that as well. Thanks.
I didn't realize the complexity of my problem and found that I couldn't get what I needed using JSF2 with the information resources available. Through my searches, I also found that many others were asking about Master-Detail CRUD applications, which I then learned was what I needed, but in slightly different ways and not getting any solid examples. A problem properly stated is half solved and I didn't know the problem statement. Armed with more knowledge, I was shocked to find that the answers were not readily available outside of some videos on YouTube showcasing Oracle ADF. In the end, I was able to quickly build the application I desired using the Play! Framework. In a way, by not having my question answered I was able to find a solution that would prove to be a better fit for my needs; though I would have gladly bought a cookbook if someone had pointed one out.

How do you database access (I/O) to/from Magento Commerce?

So, I want to import, export and modify the database. I have read that I have to do that by XML, but I don't really understand their doc system and I haven't found any good tutorials out there that explain this. I am slowly reading the very expensive and short book which is somewhat answering my questions, but I crave more.
As a second question, I want to have a order system where I can send out information or emails with my own code. I assume this would be some type of plug-in that would override or be called at a certain time. Any info would be helpful.
Some parts of the magento data can be imported/exported via the backend (System->Import/Export), namely products and customers.
If you want to deal with the complete DB - use your DB tool of choice (I prefer mysqldump).
When dealing with exported CSV.. use OpenOffice, from my experience it deals better with the separation characters than Excel.
As for your second question - as far as I understood, you will have to develop a module if you want to do something different than the existing functionality and keep the original mail functions. If you don't want to/have to keep the original functions, you can opt to overwrite the module, which is much easier as far as I can see. Google search for "overriding magento module" should turn up atleast one decent tutorial.
I found what I was looking for here:
(on magento site: Resources -> Magento Core API -> Product API or whichever API you want)
The problem is there is no Order API yet (or none that I've seen)
http://www.magentocommerce.com/wiki/doc/webservices-api/api/catalog_product#examples
This details how you'd write an external php script and obtain,edit or delete products (or anything else with an API).
Modules still look daunting, but I am reading through the (very thin) magento book (the only one available).
I hope this helps someone else.
