Study Notes
Internet of Things (IoT)
- IoT is the network of physical objects embedded with electronics, software, sensors, and network connectivity that enables these objects to collect and exchange data.
- IoT is everywhere and has various applications.
Smart Home
- A smart home is a house with appliances that are connected to the internet and can be controlled via smartphone.
- Features of smart home technology include:
- Control: lighting, TV, thermostat, appliances, door locks, and more
- Convenience: automatically reduces TV volume when receiving a land-line call
- Security: door locks and security systems
- Health: monitoring and responding to health needs
Big Data
- Big data is high-volume, high-velocity, and high-variety information assets that require new forms of processing to enable enhanced decision making and insight discovery.
- Characteristics of big data:
- Volume: exceeds limits of traditional relational databases and grows constantly
- Velocity: arrives rapidly and often in real-time
- Variety: does not have a standard structure (e.g., text, images, audio)
Data Structures
- Four main types of data structures:
- Structured data
- Quasi-structured data
- Semi-structured data
- Unstructured data
Generation of Big Data
- Sensors gathering information (e.g., climate, traffic)
- Social media: posts, pictures, and videos
- Digital satellite images
- Purchase transaction records
- Mobile phone GPS signals
- High-volume administrative and transactional records
Data Analytics Lifecycle
- Discovery: identify problem or opportunity
- Planning: define problem, determine objectives, and identify data needs
- Data prep: collect, clean, and transform data
- Model building: develop and refine models
- Operationalize: deploy and monitor models
- Communicate results: share insights and recommendations
Industry Examples for Big Data Analytics
- Healthcare: reducing cost of care, preventing pandemics
- Life Sciences: genomic mapping, unstructured data analysis
- IT Infrastructure: phone/TV, online services, retail, financial services
