Question
Conduct a systematic literature review of at least five recent (2015-2017) articles on big data by doing the following:
1- Present a summary of the findings in a table.
2- Write a synthesis of the literature.
(Identify relevant theories, concepts, specify the gaps in existing knowledge, compare and contrast, and describe how the literature relates to YOUR research)
3- Give the operational definition of the key variables/constructs/concepts used in your study.
An operational definition is a definition of a variable/construct/concept in practical, observable, and measurable terms.
Explanation / Answer
A literature review is a good instrument “to identify gaps in current research in order to suggest areas for further investigation ”thus, a systematic literature review (SLR)in line with Kithenham is applied to investigate these gaps that are of interest to foster the evolution of the EA management discipline. This SLR provides an overview about existing work. The research approach is based on secondary data, because secondary research data is available immediately and a large amount of experience can be accessed covering a wider area of interest. According to kitchenham a SLR is composed of three main phases : planning the review ,conducting the review ,and reporting the review .the planning of the review includes the identification of the need for a review and the development of a review protocol. The rationale for this SLR is an explanation of the proposed lack of EA management to the changing environment and new trends
Literature identification:
The first step of a systematic literature review is the definition of the literature sources .as far as a board overview about existing research is pursued ,the search is confined to the database ACM digital library, the ACM digital library contains all ACM publications,including journals and conference proceeding
Serach process:
The search process utilizes the defined literature sources to identify relevant literature following a defined structure.the search process consists of the following steps .
Search criteria construction and manual selection process
Search criteria construction :we designed specific search strings that are applied to the selected sources .they are like
Explicitlt started requirements inthe big data context
Challenges in the big data context that allow a derivation of requirements
Experiences in big data projects and big data management that lead to a set of requirements for EA management
Manual selection process:
A manual selection process is applied during reading the abstracts to exclude literature with the following characteristics
No architectural problems,challenges or requirements are described
Scope of the literature is too technical and
As the identified literature is a sample ,the above mentioned steps are performed to keep this sample as representative as possible to ensure valid results
Analysis and interpretation:
The requirements that are exists in the big data context the current Ea and big data projects have a bilateral relationship. while the current EA constrains the possibilities of these projects .it is also transformed by big data projects
