This BMP4005 individual poster and accompanying paper on information systems and big data analysis covers the history, challenges, techniques, and characteristics of big data. It also explores how big data technology can support businesses with examples. The poster and paper are based on the concept of data storage, analysis, and effective use of big data. The challenges of big data analytics include securing data, lack of knowledge professionals, poor selection of big data tool, and integrating data from a spread of sources. Techniques that are currently available to analyze big data include classification of tree analysis, association rule thumbing, and machine learning. The characteristics of big data are volume, variety, velocity, and value. The paper cites Zeadally et al.'s (2019) research on smart healthcare to support the potential solutions using internet of things (IoT) and big data analytics.
