Open Source Database Systems. Edition No. 1
VDM Publishing House, March 2010, Pages: 68
Database systems have been studied over three decades. The methods used in modern systems are well understood. The movement in the Open Source community and the development of open source database systems give subject to new considerations. The source codes of the products are public and their non-commercial use is free, whereas the prices of commercial databases are very high. A free or inexpensive open source database could be a real option to many enterprises if only the functionality of it would meet today's high requirements. High performance, support for transactions, automatic recovery and scalability are the basic requirements. High availability is often desired as well. Theory behind transaction management, storage structures, concurrency control and availability is presented. The open source database market is surveyed and some open source database systems are selected for further investigating and experimenting. The techniques and methods used in the databases are presented and compared to the theory. The experiments are done in a mobile telecommunications environment, a modern business area involving a large amount of data processing.
