Service Oriented Architecture (SOA) technology is beneficial for a number of business services including Saas(Software as a Service). Using this technology, scalable and flexible solutions shall be developed using reusable services based on components and composites that can be used for Saas(Software as service) solutions as well. Binding for the services (ex.webservice) shall be changed without changing the source code that gives a lot of integration advantages, flexibility and interoperablity over conventional methods. However this technology needs a lot of research and expertise to develop applications. BQ Technologies started SOA research and development in early 2007 and successfully developed applications based on this technology. Saas services shall be developed and hosted that minimize the maintenance cost and maximize the return from investment. BQ Technologies is one of the best SaaS software vendors in the IT industry.
