Companies prefer open source database to proprietary database because of a lot of reasons. Of course, if you are thinking about what database to use, you should do a comparison between the features offered by the databases and identify the features your company would have a need for. Open-source license database has the edge of missing susceptibility to over-deployment and other compliance-related problem. Vendors of databases with proprietary licenses have named this issue as top license compliance problem. With an open database, you do not have to deal with companies suing you for not complying with license agreements because the software license is free.
Another fantastic thing about an open source database is its reputation for having a good amount of software support. The highly regarded ones are backed with a large community of users and professionals who diligently monitor and report bugs and security problem, while the source code people are usually more than willing to fix the problems right away. Open source database has minimal staffing costs associated with it. Compared to top proprietary databases, some reliable open source system has low maintenance and low requirements for tuning, without sacrificing performance and stability. The impressive stability of open source system can be demonstrated on instances when there is high user activity and the system still continue to function normally.
There are many other notable elements of open source database. Several of the top free databases are impressive when it comes to how easy it is to extend and adapt them. Altering source codes is simple and at no cost to users. These functions are not easily available on a proprietary software. When it comes to the openness feature of software, the more open the database is, the easier it is to complete integration with other software. There is also nimbleness, a quality of some open license database which means ability to integrate current trends.
