These types of databases emerge as a result of the rigidity shown by traditional databases to handle today�s data which is voluminous, highly diversified and generated at a very high rate. With NoSQL, problems such as database expansion difficulties, low query performance and low storage capacity are addressed. However, the inherent complexity of contemporary datasets coupled with programmers� low NoSQL modeling competence are increasingly making database modeling and design vastly challenging, especially when parameters like consistency, availability and scalability are to be balanced in accordance with system requirements. As such, a schema suggestion model for NoSQL databases is posed to address this balancing issue. The proposed model aims to abstractly suggest schemas at the initial stage of system development based on user defined system requirements and CRUD (Create, Read, Update and Delete) operations among others. This is achieved through the adaptation of exploratory and experimental approaches of research. Also, few mathematical formulas are introduced to calculate clusters availability during entity mappings. A comparison was conducted between the schema produced using the proposed model and the one without. Results obtained shows substantial improvement in the areas of security and read�write query performance. © 2018, The Author(s). date: 2018 publisher: SpringerOpen official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85058048573&doi=10.1186%2fs40537-018-0156-1&partnerID=40&md5=f24c133db333ae085763516b6656d578 id_number: 10.1186/s40537-018-0156-1 full_text_status: none publication: Journal of Big Data volume: 5 number: 1 refereed: TRUE issn: 21961115 citation: Imam, A.A. and Basri, S. and Ahmad, R. and Watada, J. and González-Aparicio, M.T.
