“…Business processes, workflows, and scenarios represent the behavioral aspect of the problem . Problem domain attribute represents a characteristic or property of the problem domain or migration problem. Examples of the business domain properties include the following: cost of migration , feasibility of migration , and value of reuse . Quality requirements specify the envisioned quality requirements of the target service‐based system as well as those of the pre‐existing system. We found very few approaches that address quality requirements in migration.…”

“…We found that using different design constraints such as coupling or cohesion; the migration approaches specify the characteristic of legacy elements that are suitable to be migrated to services. For instance, the legacy elements that are loosely coupled [32,36,38,46,47], or are well granular [38,39,48,49].…”

When Service Orientation was introduced as the solution for retaining and rehabilitating legacy assets, both researchers and practitioners proposed techniques, methods, and guidelines for SOA migration. With so much hype surrounding SOA, it is not surprising that the concept was interpreted in many different ways, and consequently, different approaches to SOA migration were proposed. Accordingly, soon there was an abundance of methods that were hard to compare and eventually adopt. Against this backdrop, this paper reports on a systematic literature review that was conducted to extract the categories of SOA migration proposed by the research community. We provide the state‐of‐the‐art in SOA migration approaches, and discuss categories of activities carried out and knowledge elements used or produced in those approaches. From such categorization, we derive a reference model, called SOA migration frame of reference, that can be used for selecting and defining SOA migration approaches. As a co‐product of the analysis, we shed light on how SOA migration is perceived in the field, which further points to promising future research directions. Copyright © 2015 John Wiley & Sons, Ltd.

“…The fourth stage manages these reusable components in a software environment. Zhang Li, et al, [16] have provided a modernization process called Tollgate Model Transformation with which the legacy system can be adapted to a services oriented architecture (SOA) system whose granularity is changeable. The Tollgate Model Transformation process is based on the wrapping technique.…”

“…The Tollgate Model Transformation process is based on the wrapping technique. The Aberdeen Group [17] did a survey of the legacy application modernization and found that companies are looking to the SOA approach to create distributed applications to help them both modernize their legacy applications and to make their composite applications more flexible and therefore giving their businesses more agility. Some companies, however, are looking to simply get rid of legacy applications on mainframes and UNIX servers to get rid of the legacy problem.…”

Storing, analyzing and accessing data is a growing problem for organizations. Competitive pressures and new regulations are requiring organizations to efficiently handle increasing volumes and varieties of data, but this doesn't come cheap. And as the demands of Big Data exceed the constraints of traditional relational databases, evaluating legacy infrastructure and assessing new technology has become a necessity for most organizations, not only to gain competitive advantage, but also for compliance purposes. The challenge is how well the organization's legacy infrastructure integrates Big Data. It is without a doubt that one way or another Big Data must be accommodated by legacy systems. Legacy systems contain significant and invaluable business logic of the organization. Organizations cannot afford to throw away or replace this business logic. These legacy systems are assets of the organization. These invaluable assets of encoded "business logic" represent many years of coding, development, real-life experiences, enhancements, modifications, debugging etc. Most of the legacy systems were developed without the process models or data models-now needed to support and integrate Big Data. To integrate Big Data into legacy system, modernization of legacy system is required. There are many approaches for modernization of legacy systems but none of them are focused on integrating Big Data into legacy systems. Legacy systems hold valuable data too important to be lost in the process of modernization. However, addressing the issues and scope related to incorporating Big Data with legacy systems allows mature legacy systems to become part of groundswell changes. There are many areas unaddressed about integration of Big Data into legacy systems. Incorporating data from new sources, specifically "live" sources, into existing legacy systems is a technical challenge. Moreover, the sheer volume of Big Data can be daunting. Our paper presents the scope of integrating Big Data into modernization of legacy systems.
