Describe the development process of Object oriented methods
Object oriented methods have roots which are strongly anchored back in the 60s, functional and structured methods were first to be used. This is not very uncommon, as functional methods are inspired directly by computer architecture (a proven domain, well known to computer scientists). The separation of data and program as exists physically in hardware was converted into functional methods. This is the reason why computer scientists got into habit of thinking with respect to system functions. Later it was felt which hardware should act as servant of the software which is executed on it rather than imposing the architectural constraints on system development process.
