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,
Shashi
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:

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.

I'm developing an app with one of my friends and it'll use an Oracle database. We can sync the code with github but what about the database? Is it possible to somehow use git for that as well?
I assume the recommended approach would be to use a central online database somehow. Where do I start with that? Docker? We are both inexperienced in web development. We also have no requirement to make the database online(it's a university course project) so I do not want to go through that hassle if possible.
You can store your SQL scripts (like your DDL commands to create your tables, etc.) in GitHub, just like any other code, but your Oracle database won't interface with it directly. You can use Oracle's SQL Developer as an IDE to interface with GitHub.

Traditional Oracle is free for academic and training purposes, and there is also a free cloud offering now as well. You can run it from a laptop, a VM using VirtualBox, or from the Oracle Cloud. Unless you need a specific option with Enterprise Edition, your best (least complicated) bet, is probably to go with the Oracle 18c XE version, available here: https://www.oracle.com/database/technologies/xe-downloads.html
We built a commerical tool that helps database developers use Git with the Oracle Database. It tracks the changes in database objects and helps you to commit them to Git. It might be worth takinga look: https: www.gitora.com
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.
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
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 completely ignorant in relation to databases and servers etc. Please bear with me.
I am trying to install a program called RealProspect 2009 which allows both local and remote sql database installation. Both types are done using the program installation .exe.
I have an azure account on which I have set up a server, and a database. During the program installation I am asked to provide the SQL server address, SQL server name, SQL username and SQL password. Using the information provided in the Azure online tools, I input all of this information into the fields and the program commences installing the database on the remote location. If I use incorrect information in these fields the installation returns an error and tells me it cannot log in, or the IP is not allowed etc., so I know it's actually attempting to connect and verifying the connection credentials.
When I use the correct server and login information the program proceeds. It spends several minutes "Creating the Tables". When it finishes doing that it attempts to begin "Installing Default Data (Categories)". At this point the program stops and I get the error in the subject line of this post "Invalid Object name 'Categories' "
I don't know enough to tell you what I don't know about this process.
I just signed up for Azure specifically because hosting the database with Azure is like $5-10 per month and I want myself and several other participants to be able to use the software with a common database. I created the server and database using the gui "tools/how to" from within the online Azure portal and I have never written a script, or accessed the server/database using anything other than the online GUI.
Thank you in advance for any help you may be able to provide. I hope i'm not too much of a speed bump to your day.
P.S. - For what it's worth you can download a free trial of the software from realinvestorsoftware.com and see if you could install it on a remote server. Maybe you can better see what I see and tell me how to do it on my own?
SQL Azure is VERY similar to SQL Server but there are a few features that SQL Azure doesn't support. That said, I'd be surprised if the app's installer is using any of the features that are unsupported by SQL Azure. My guess is that there's a bug in their installation scripts that might fail on more modern versions of SQL Server (note, their app installs on SQL Express 2005 which is no longer in mainstream support).
Just a couple of other thoughts for you: You get keys to install the app on two machines but:
"If you would like to install on more than two computers, then after you order your copy of RealProspect you can login to your customer account on this website and order additional activation keys for only $97 each."
Because you're going to be paying several hundred dollars anyway, and because (you yourself admit) you're not a database expert, it may be less cost, stress and hard-work to use their $27 per month database hosting service. That way you can concentrate on building your business while they take care of the technology.

Another option Chris presented was to install the app and database locally and then migrate the database to Azure.
While this is potentially feasible, it requires some finesse to execute.
Microsoft provides a DB migration guide presenting several (pretty manual) options.
You might also want to read this thread which discusses how to migrate your DB via a DACPack.
Another option is to download and use the SQL Azure Migration Wizard which should do most of the heavy-lifting for you and make your DB migration simpler.
However, note that it is possible that the DB the app uses may use features of SQL Server that are not supported on SQL Azure. Hopefully this isn't the case, but be aware that this may be an issue.
Good luck :)
Chris,
I think SQL Database Migration Wizard v3.9.10 & v4.0.13 will solve your problem, I have used this tool several time to migrate db from local machine to sql azure, the most beauty of this tool it also highlights the error or sql which couldn't be migrated to Azure, so we can easily find alternate syntax of such sql queries
