In this digital era, businesses are making use of NoSQL technologies for managing such Big Data. However, the NoSQL database systems come with inherent security issues, which pose a major challenge to many\u0000organisations worldwide. There is a paucity of research studies for exposing the security threats and vulnerabilities of NoSQL technologies comprehensively. This paper presents an in-depth study of NoSQL security issues by performing a detailed comparative study of the security vulnerabilities identified in\u0000NoSQL database systems. A set of key security features offered by the four commonly used NoSQL database systems, namely Redis, Cassandra, MongoDB and Neo4j are analysed with an aim to identify their strengths and weaknesses. The vulnerabilities associated with built-in security, encryption, authentication/authorization and auditing that impact Big Data management are compared among these popular NoSQL database systems and the risk levels are identified. In addition, illustrations of possible injection attacks experimented with these NoSQL systems are provided. Finally, a high-level framework is\u0000proposed for NoSQL databases with considerations for security measures in Big Data deployments. The discussion forms a significant technical contribution for learners, application developers and Big Data deployers paving way for a better awareness and management of the NoSQL systems in an organization.","PeriodicalId":335930,"journal":{"name":"International Journal of Managing Information Technology","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122340928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To develop ontology, it applies knowledge engineering concept and using Protege Ontology Editor version 3.5 beta and version 5.5 beta to process the data for the accurate system development according to user-centered design concept. The study findings were the developed system is able to support information exchange, information retrieval, and research search and to decrease research redundancy and unnecessary budgeting. Moreover, the system could possible enhance conducting more innovations, confirming experts in the area, showing research trends, and showing research results on related fields, strategies, and problems which leads to the Southern developments extensively.

The company’s extremely large amount of R&D funds is the result of an ample free cash flow generated by sophisticated cash conversion cycle (CCC) management. Increased R&D induced business advancement and lean cost structure construction leading to further increase in cash flow which has stimulated interaction between vendors, customers, and Amazon via the Amazon marketplace. Activated interaction accelerated CCC advancement, a subsequent free cash flow increase, and user-driven innovation, thus accelerated the transformation of routine or periodic alteration activities into significant improvement simultaneously. All of these components function together as a consolidated sophisticated machine. In light of the increasing concern to R&D resources development without the dilemma of a productivity decline that most digital economies are now confronting, this paper demonstrated the above hypothetical view. An intensive empirical analysis focusing on the development trajectory of Amazon’s techno-financing system over a period from 1997 to 2018 was conducted. An insightful suggestion to neo open innovation that fuses financing management and R&D management was thus provided.","PeriodicalId":335930,"journal":{"name":"International Journal of Managing Information Technology","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121683070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By means of a comparative empirical analysis of respective development trajectories, the sources of their success were analyzed thereby the comparative advantage and disadvantage of each respective trajectories supportive to find a practical solution to the critical problem of a dilemma were identified. The sources of both successes can be attributed to harnessing the vigor of soft innovation resources from the marketplace.

This framework aims to align the IT services with the business needs by insuring the quality of services provided to business. This IT service Management system links people, processes and technology within the Central Bank of Sudan as the main site of the project. The Central Bank of Sudan is the main bank that governs Sudan's banks rules and regulations. The bank was formed in 1960 with headquarters located in the Khartoum capital of Sudan in addition to eighteen (18) branches spread throughout the country. The Information Technology Administration within the Central Bank of Sudan manage and operate the IT infrastructure that host and support all systems that used internally and for external banks. The objective of this study focused on finding IT service management system that can support international IT service management platform that can apply ITIL standard processes like Incident Management, Service Request Management, Problem Management, Change Request Management, Configuration Management Database and Knowledge Management. The methodology used in this system is the Rapid Application Development (RAD), a condensed development process that produces a high quality system with low investment costs. The proposed system went through to alpha, beta and acceptability tests by IT development team first and second line of support agents to ensure proper module functionality with favorable results. The study concluded in align services provided by the Information system department with business need through manageable and controllable standard. As a recommendation, the system should be implemented at the Central Bank of Sudan. More integrations and benchmarking must be done to ensure modules functionalities and higher security.
