Modeling and Management of Big Data in Databases
The main real-world datasets used in the studies analyzed for this paper were sensor data, image metadata, website publications, and electronic documents. Most of the studies analyzed did not document the specific languages they used to model their data or the tool they used. But due to the need to analyze large volumes of data with various structures, which arrive in high frequency, database research became more focused on NoSQL than relational databases. Why might a NoSQL vs. Relational approach be best for database management, according to growing trends captured in this review of research?
2. Method
2.3. Reporting the SLR Study
The objective of this step is to answer the research questions raised in the review protocol. For this purpose, this study is divided into three parts. In the first part, we perform a bibliometric analysis to answer RQ1; in the second part, we present the literary review with the most relevant data of the approaches in a concept matrix to answer RQ2; and in the third part, we discuss the trends and gaps to answer RQ3. Section 3 presents in detail the results collected from the activities described in this phase.
