JCOM_V1_N3_A1 Jyoti Rana Journal on Computer Science 2347–6141 1 3 1 8 SOA, MDM, BPM, Cloud Computing, REST, ESB, BaaS, EAM, BPM SOA [Service Oriented Architecture] and service-orientation have laid the foundation for a variety of emergent service technology innovations, while the original building blocks of SOA and service-orientation continue to evolve by embracing fundamental service technologies, concepts and practices. These new technology innovations do not replace service-orientation; they use it as their basis. Service-orientation continues to evolve towards a factory approach, towards industrializing integrated platforms, such as BI, Master Data Management (MDM), mobile front-ends, BPM, adaptive processes, Big Data and Cloud Computing - all of which add architectural layers upon SOA-based infrastructure. All of these technologies can interface via standardized data and functions, published as service contracts, in order to avoid redundancy - that's service-orientation [3]. Advance software modularity focuses on the novel requirements of modularizing and uniting software schemes on desires and architecture plans such as [1,2]. Aspectoriented requirements engineering, Requirements and architecture design techniques for software product line engineering; Requirements engineering for service-oriented systems [12]. This paper basically deals with requirements engineering for service-oriented systems, needs for SOA, SOA practices in the mobile age, industrial SOA toolkit, it's maturity as well as SOA & user interfaces.
