Dual Database Design.
Koha uses a dual database design that utilizes the strengths of the two major industry-standard database types (text-based and RDBMS). This design feature ensures that Koha is scalable enough to meet the transaction load of any library, no matter what the size. .

Library Standards Compliant.
Koha is built using library standards and protocols that ensure interoperability between Koha and other systems and technologies, while supporting existing work-flows and tools. .

Web-based.
Interfaces. Koha's OPAC, circulation, management and self-checkout interfaces are all based on standards-compliant World Wide Web technologies--XHTML, CSS and Javascript--making Koha a truly platform-independent solution. .

Free / Open Source.
Koha is distributed under the open-source General Public License (GPL). More information on the GPL can be found here. Koha is available for free download and also in OpenLX DVD.

No Vendor Lock-in.
It is an important part of the open-source promise that there is no vendor lock-in: libraries are free to install and use Koha themselves if the have the in-house expertise or to purchase support or development services from the best available source.
