I am thinking about developing an application to store a movie database, allowing the user to store information about which movies it owns, which movies it wants to see, etc.
I was thinking of developing this application with the Qt framework and using MySQL to to the database part.
However, I have a few questions. When deploying my application on other machines, won't I need MySQL installed there too? Or will the .dll suffice?
Can I connect to a database that does not exist, on a machine that does not have MySQL installed?

My company has two web based project. Our main project (Starbooks) was built using xampp server and Codeigniter framework that installed in our Windows OS and the second project (Frontlearners) was built in Lamp server and moodle (LMS) framework with Postgres database that installed in ubuntu platform.
My goal is to collide this two projects into one by moving the second project (Frontlearners) into the main project (Starbooks) server which uses with xampp server windows platform.
My first attempt is to export the moodle Postgres database using PGAdmin then move the moodle project to the main project server on windows. But I don't know if this is the correct way or not because Postgres and mysql are different database type. I've searching across the internet hoping for the answer or tutorial related to my problem but the results are always fresh installation of moodle which is not related to my problem.
Anybody knows how to solve this problem, a tutorial link, or any article about this situation?
There is a database transfer tool in Moodle.
https://docs.moodle.org/311/en/Database_transfer
So you can convert the PostgreSQL database to MariaDB
First ensure MariaDB is installed on Ubuntu
Turn off cron and put the site in maintenance mode
Then go to Site administration > Development > Experimental > Database migration to convert the database.
Or direct to /admin/tool/dbtransfer/index.php
The tool will check the database structure matches the structures in the install.xml files. If there are any differences, then you will need to update the relevant install.xml file or database table before continuing.
If its a large database, then the UI will probably time out. So use the command line version instead:
php admin/tool/dbtransfer/cli/migrate.php --help
Having said all that, IMHO I would transfer the Windows project to Linux.
I bought "Hetzer" server so I can create my own database and practice a little bit. My server is using Ubuntu. I plan to also create a script (probably in node or asp) so my android application can communicate with database.
How to start with creating database, what to do?
Firstly https://www.hetzner.com/ is one of the best professional web hosting providers. In order to set up your Mysql server to your ubuntu machine. Install lamp stack. There are many tutorials about installing lamp. Then open your DB for remote connection or do kind of restful service to access your data in DB.
I am designing a JavaFX application with MS Access database for both Windows and Mac Platforms. My local friends suggests that I place the database file under "user.home" folder. Then, the database would be under "C:\Users \
{Username}" folder. But, would it be accessible for another user of the windows or mac?
And one more confusion, is it possible or considered best practice to deploy JavaFX application to for all users of the system. I have only found out that JavaFX self-contained applications are all installed for one user only.
I am trying to design a database application for my small business. I've created a number of form driven MS Access databases for use before but would like to create a permanent solution in something more advanced & common.
I was thinking of using mySQL for the database and would then program a C# or VB application to be used in Windows. I do not want or need a web based version at this time but the migration to VB.net in the far future may be something I'll look into.
I know I can use a MS Access backend for my windows application without having to install MS Office on any or all the computers the program will be run for.
But here is my question. Is it necessary to install mySQL Server on the PC hosting the database, on all the PCs accessing the database or can I just use the database file as the backend and Visual Studio will have all the necessary tools I need to access it?
If I have to install the server I may just stick with the MS Access database as the needs for an excessive amount of database storage won't ever be an issue.
You'd need to install MySQL server on the Server hosting the database. The clients would then connect via the network. You will however need a driver to access the MySQL-Server with VB.NET on the client machines. A simple DLL-File might be enough, though.
If you are looking for a file-based database solution have a look at SQLite. But you will have to watch out for concurrency issues here.
I would like to have a Flash Application (not air) to connect to a local database.
Air is not only getting unsupported by Adobe in LINUX but besides, it has serious problems and miss implementation with SQLite.
So we want to connect to a local MySQL database.
This application should be simple, so we do not want to also have an unnecessary web server (also local) to make a middle communication between the flash app and the MySQL server.
There is this driver that allow to communicate Flash with MySQL

Question is:
Is this the best approach?
Would it be any problem using this approach when installing the whole application to each client? (because we also in the installation should install a MySQL server).
A MySQL SERVER is called a SERVER for a reason: It is meant to be installed on servers, not on clients. So the answer to your question is:
1) No, this is not the best approach. Not even close. You would be better off using a SQLite database (however shitty you may think it is)
2) Yes. Nobody would like installing a MySQL server on their computers just for the sake of running your application. Think of casual (non-expert) users who would need to install and configure the server just for running your app. That is the very REASON why they developed SQLite and so many languages support it.
You should check out http://code.google.com/p/air-sqlite/ for sqlite access in AIR (I don't know if this is the same as the inbuilt code or not, so just check that out)
