I am working on my Java application in Eclipse that connects to the database and makes some queries with the data. This database has been created and managed in PHPMyAdmin. The database is stored locally and now I would like to make it accessible not only from my computer, but for anyone who will run my application on his computer. Can anyone tell me what is the procedure? How can I make the database "online"? Should I store the database on some remote server? If so, what is the procedure?
I know this question is not so much straight-forward, but I hope you will give me some idea how to deal with it.
Thanks in advance!
In this situation you should store the database on an external server who are better at managing databases with more security/backups etc.
If you're looking for scalability as well you could get an Amazon AWS Micro Instance in the cloud for free for a year which includes a large amount (20GB) of RDS (their relational database service based on MySQL) for free.
There is a great Stack Overflow question on Using PHPMyAdmin to administer Amazon RDS as well to get you started with something you are familiar with.
You can use MySQLDump to copy your current database from your local machine to RDS if you needed.
(A, completely non-extensive, list of) Mysql Hosting Providers
Webfaction - Good web user interface. Does more than just database hosting. Lots of documentation.
Amazons RDS - Cloud based. Reliable. Offers free tier
Rackspace - Cloud based. Excellent customer service.
Or, host your own on something like these
Linode - Has lots of documentation of getting Mysql installed
Digital Ocean - SSDs for great speed. Again great documentation on getting Mysql installed

I'm relatively new to databases - I've used postgresql in the past to create databases stored on my computer and accessed only by myself.
I'm currently designing a database that will be used and edited by multiple people (10-15 max) living in different parts of the world. What is the best way to ensure we will all have access to the most current version of the database? Is it best to continue storing the database on my individual computer? Should I host the database on a cloud server? I've read that it is dangerous to store databases on Dropbox.
We are social science researchers organizing our data into a single database.
Based on your comment about not always be on and connected, it seems to me that the cloud service is the way to go for you. There are two approaches there, just rent a machine ("AWS EC2") and install the database software and manage the database yourself, or use a cloud provider's managed database service ("AWS RDS"). The names are just by way of a concrete examples, there are other providers of each type of service.
Hi can someone explain to me what the following database software are:
HeidiSQL, MariaDB and XAMPP.
Also do they depend on each other to work? Hope you can help.
Thank You
MariaDB:
Is a open-source database server, basically its a fork of MySQL and they provide support and services, its slightly better than MySQL since they have made some changes to MySQL. MariaDB doesn't depend on anything. Its a complete database product.
HeidiSQL:
Its a fronend-MySQL, its nothing but a UI for interacting with different database servers like MariaDB, Percona, and many more depending on their enhancement. HeidiSQL is just a frond end, If you want to interact with databases, you must connect to one. Yes, heidiSQL is dependent on databases. Latest enhancements support MS SQL Server, which is great :)
XAMPP:
Its like a tech stack similar to LAMP, WAMP etc. XAMPP means Apache HTTP Web Server, MariaDB, PHP, and Perl. X stands for cross platform. XAMPP is dependent on many as you can see its a tech stack.
My team which is a part of a university needs me to develop a web based application for them which can be accessed by any team member. However the university doesn't provide us with a database.
We do have a portion in their server but that's for our public website. Even if I put the application on that server, I need to have a database. I can't use an excel sheet for storing all the data cause it will be huge. I am looking for an optimal solution.
Never fear there are a number of non RDBMS (Oracle, MySQL, MS SQL Server, etc.) solutions around.
You can try many of the document databases under No-SQL banner, with some popular options being:
RavenDB if you are developing your web application in the Microsoft stack.
MongoDB is a great well supported open source document database.
BaseX or Sedna are useful XML databases.
Alternately you can look to Cloud (some offer free services, others are commercial and will need to pay for) databases such as:
Amazon RDS
Elasticsearch
Windows Azure
Choose:
http://www.sqlite.org/
http://www.db4o.com/
Both will give you a database ability with no prior machine configuration or setup package.
For a small team group, specially with no more than 3 developers, I would recommend you to look at CloudBees. They offer a free tier where you can have on the same platform a repository, a Continuous Integration tool, so you can build and test your app every time you do a commit, and a runtime environment where you can deploy a Java, a Play or a PHP application. You can also create free databases.
In the case you wanted to have a visual git repository, you can use GitHub and link your source code with your Jenkins job.
In this way, you don't need multiple tools for your development environment.
I am not sure If I'm correct in posting in this forum but I need info. I am doing University project which needs couple of oracle database server which are online. I have a cloud application which would access this servers. I tried to find online if I could rent database servers for a week for the test with no luck. Could somebody provide any info on where I could rent oracle database servers.
Thanks,

Another option is to commission an Oracle instance on Amazon's Elastic Cloud (EC2). I've done this myself. If you start with an Amazon Machine Image (AMI) that already has Oracle installed, that's most of the work done for you already. Here's more info to get you started:
http://aws.amazon.com/solutions/global-solution-providers/oracle/
I imagine it would be difficult to find plain Oracle database hosting. It's an "Enterprise" thing, which means companies never bother to explain their services on their website. But you can find relatively cheap Oracle APEX hosting. (APEX is a rapid application development for Oracle.) It's probably much cheaper to rent that and use the Oracle functionality that comes with it.
Or you can always install your own system, although Oracle installation can be painful. If this is just for testing, you can download any version. You might want to start with 10g Express Edition: http://www.oracle.com/technetwork/database/express-edition/downloads/index.html
If the Amazon EC solution is unacceptable, the easiest way to go is probably to start with a Linux+Oracle VM, and look for a provider who does VM hosting, or self-host if you have access to a machine somewhere with a permanent internet connection / address.
So I'm inexperienced in hosting DB's and I've always had the luxury of someone else getting the db setup.
I was going to help a friend out with getting a webpage setup, I've got experience in Asp.Net MVC so I'm going with that. They want to setup a search page to query a db and display the results. My question I have is in getting the DB setup and hosted. They currently just have the Access DB on a local computer. There is basically only one table that would need to be queried for the search.
What is the best approach to getting this table/db accessible? They would like to keep the main copy of the db on the local machine, so copying the entire db over to the hosted site would be time consuming, could the lone table needed be solely copied to the host? Should I try to convince them to make changes on the hosted db and just make copies of that for their local machines? Any suggestions are welcome, Again I'm a total noob when it comes to hosting databases.
Thanks
Added: They are using a MS Access 2000, and the page will have access restrictions. Thanks for the responses.
How about SQL Server Express? I think you can do a remote connect from Access and just push the data over from Access.
I wouldn't use Access on a web server in any case.
I would strongly recommend against access from web work, its just not designed for it and given that SQL server express is free there is no reason not to give it a go.
You can migrate the data over by using the SQL server upsizing wizard, here is a link for help on using that feature

It depends on what you mean by web work? Access 2010 can build scalable browser neutral web applications. They can scale to 1000's to users. In fact, you can even park the web sites on Microsoft's new cloud hosting options, and scale out to as many users as you need.
Here is a video of an application I wrote in access 2010. Note how at the half way I run the same application including the Access forms in a standard web browser. This application was built 100% inside of the Access client. The end result needs no ActiveX or Silverlight to run.
http://www.youtube.com/watch?v=AU4mH0jPntI
So, the above shows that access can now be used to build scale web sites (you can ignore the confusing answers by the other two posters here they are not quite up to speed on how access works or functions).
However, for your case, I would continue to have the access database on the desktop. You can simply link to tables that are hosted on the web server. Those tables can exist in MySql, or sql server. As long as the web site supports external ODBC connections (many do), then you can thus have the desktop application use the live data from the web server. If connections to the live data at all times is a issue, then you could certainly setup something to send up new records (or the whole table) on some kind of interval or perhaps the reverse, and pull down new records on a interval from the web site (depends which way you need to go). So, connecting to MySql or sql server is quite easy as long as the web hosting and site permits external ODBC connections. I do this all the time, and it works quite well.
As mentioned, new for access 2010 is web site building ability but that does requite Access Web services running on SharePoint.
You don't need to upgrade to Access 2010. One option is to use the EQL Data plugin to sync the database up to the server. Then you can write an asp.net, php, or whatever application that queries the table using the EQL API and prints the results however you want. This kb article describes how to use the EQL API from a web app.
The nice thing is that the database is still totally usable (and at full speed) even when you're not online, and then you can sync the new data up to the web occasionally. It only uploads the changes, not the entire database every time, so it's fast.
Disclaimer: I work at EQL Data so I'm a bit biased. But this kind of use case is the whole reason the company exists.
