Java Forum / Databases / March 2006a database for free
Hi all, I am developing a software for a small inventory application.I have to sell it to my customer. I want to use a free database for my project.For my application to run at the ustomers office, my customer also needs the database.I am using java as front end.So is there any database that i can use free of cost to develop my application and make my customer also get the database software without any cost so that my application will run at his office. If I use hsqldb will I face any license issue.Can anyone please help. > Hi all, > I am developing a software for a small inventory application.I have to [quoted text clipped - 5 lines] > software without any cost so that my application will run at his > office. Oracle, IBM and Microsoft have versions of their databases (Oracle, DB2 and SQL Server) that are free to use and distribute with your application. I guess Oracle and DB2 are better choises when using Java. > If I use hsqldb will I face any license issue.Can anyone please help. From the FAQ: May I use HSQLDB in a commercial product? Yes. HSQLDB is Open Source and free to use in any commercial product so long as the terms of the Licenses are met. The Licenses of HSQLDB and Hypersonic SQL (on which HSQLDB is based) are both based on the new BSD License. -- Arto Viitanen, CSC Ltd. Espoo, Finland Thank you Arto. Wll i have to give my java code also as open source if i use java and hsqldb?If anybody knows please help me. > Thank you Arto. > Wll i have to give my java code also as open source if i use java and > hsqldb?If anybody knows please help me. I assume you don't have to. This is taken from the hsqldb license: Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.

Also there was a similar question asked in the forum on sourceforge: http://sourceforge.net/forum/forum.php?thread_id=1243991&forum_id=94352 where Fred (the maintainer of HSQLDB) clearly answered "Yes, it is free to use in binary form" To be sure you might want to ask again describing your situation. Fred is very helpful in answering questions.

Using code is different from extending it.

No, you don't have to give away your code if you use an open source library or something similar. You only need to give away your source code if you extend the library or whatever you are using. That's basically the idea behind open source - everyone may use it, but everyone must also be able to benefit from the modifications you made. And even if you modify an open source library, you don't have to give the code to your project away - only the modifications you made to the open source library.

This is not true for all open source licenses. The Apache license allows you to make modifcations and redistribute without giving it back (although you are encouraged to do so). The details can be found here http://www.apache.org/foundation/licence-FAQ.html Signaturedt <snipped> > This is not true for all open source licenses.

But isn't the Apache license a separate license on it's own? I must admit that I do not know all the details of open source, only that I stumble upon decent OS projects very regularly.

Here's a starting point for learning more about open source software licensing. http://en.wikipedia.org/wiki/Open_source_license Note the large number of distinct licenses -- and these are just the licenses approved by the Open Source Initiative! The GNU Public License is the one most people think of as "viral." That is, if you distribute some software licensed under the GPL, your own software you distribute with it automatically becomes licensed under the GPL as well. There is also a GNU Lesser Public License, which is widely used for software libraries, to permit use in commercial distributions without causing the proprietary software to have to adopt the GPL. Also see http://en.wikipedia.org/wiki/Viral_license. There are many other specific open-source licenses, some of which may be "viral," but many of which are not. Finally, the best policy is that no one should *ever* rely on legal advice from internet folks like us. Read the licenses for yourself, and consult a lawyer to double-check. Regards, Bill K. >> Thank you Arto. >> Wll i have to give my java code also as open source if i use java and [quoted text clipped - 12 lines] > code to your project away - only the modifications you made to the open > source library. Unless the library is GPL licensed (which hSQL isn't), in which case any use requires everything using it to be GPL as well. > Hi all, > I am developing a software for a small inventory application.I have to [quoted text clipped - 6 lines] > office. > If I use hsqldb will I face any license issue.Can anyone please help. There are countless other open source database out there: mysql, firebird, postgress, etc All of the mentioned are used quite a lot in a business/production environment. ut of course no where near as much as oracle, db2 or sqlserver. You can search freshmeat.net or sourceforge.org if you want to find other open source sql databases. /tom >> Hi all, >> I am developing a software for a small inventory application.I have to [quoted text clipped - 16 lines] > > /tom Yup, lots of alternatives exist. The character of the project should determine which variant to use. Any small-footprint java-based database, like hsqldb, mccoy etc. would be very simple and convenient to integrate into the java project itself. However, many pros and cons should be considered. What if you have a small project now and want to re-use code in a larger project later where hsqldb doesn't quite cut it? Could be better to go for Oracle then, or PostgreSQL/MySQL (I prefer PostgreSQL for it's mature design and featureset) if opensource is a requirement. My SQL is the free DB which used for most host providers as main DB. But there are problem with nested "select" For ex: "select * from select ... " If I remeber after version 4 it is not a problem any more. > Hi all, > I am developing a software for a small inventory application.I have to [quoted text clipped - 6 lines] > office. > If I use hsqldb will I face any license issue.Can anyone please help. > My SQL is the free DB which used for most host providers as main DB. > But there are problem with nested "select" > For ex: "select * from select ...

However, not all ISP's who support MySQL have upgraded to 4.1 yet. MySQL 5.0 was released into production in October 2005.

Sorry one more thing... If I recall correctly, if you develop an application based on MySQL then sell it to a customer, I believe the customer has to have purchased a license of some sort from MySQL Corporate to be in legal compliance... Of course, I could be wrong, so check MySQL FAQs or inquire directly. That said, several of the other free (or free version available) database that have been mentioned have no strings attached licenses. > and tons of licensing issues... > [quoted text clipped - 12 lines] >>> office. >>> If I use hsqldb will I face any license issue.Can anyone please help. > Hi all, > I am developing a software for a small inventory application.I have to [quoted text clipped - 6 lines] > office. > If I use hsqldb will I face any license issue.Can anyone please help. Derby has the Apache license. And you can embed it in your java app if that suits your needs http://db.apache.org/derby/ Signaturedt > Hi all, > I am developing a software for a small inventory application.I have to [quoted text clipped - 6 lines] > office. > If I use hsqldb will I face any license issue.Can anyone please help. Have a look at either MySql (open source) or Oracle XE. Personally (coming from a deep Oracle background) I'd choose the XE - you get the Oracle database for free, you can even use it in production for free. The only catch is that the database size may not be bigger than 4GB, but for small applications this is almost never a problem.
