Study Notes
Understanding Big Data
- Big data involves collecting and processing large amounts of data from multiple sources, often in terabytes or petabytes.
- Three main actions are required to make big data work: integration, management, and analysis.
Integration
- Integration involves receiving, processing, and transforming raw data into a usable format for business users and analysts.
Management
- Big data requires significant storage, often using cloud solutions to take advantage of unlimited compute and scalability.
- Data must be stored in a format that can be processed and made available in real-time.
Analysis
- Analysis involves exploring the data and communicating insights across the business in a way that everyone can understand.
- Data visualization tools are used to create charts, graphs, and dashboards to facilitate understanding.
Applications of Big Data
- Big retail stores use big data to track customer spending habits and shopping behavior.
- This information is used to provide personalized product recommendations to customers.
Tableau
- Tableau is a data visualization tool that can connect to multiple data sources and create interactive visualizations without requiring coding knowledge.
- Features of Tableau include powerful data discovery and exploration, support for multiple data sources, and centralized data source management.
R Language
- R is a language and environment for statistical computing and graphics.
- R provides a wide range of statistical and graphical techniques and is highly extensible.
- R is available as free software under the GNU General Public License.
Cloud Computing and Big Data
- Cloud computing providers often use a "software as a service" model to allow customers to easily process data.
- Big data is often generated by large, network-based systems and may require artificial intelligence and machine learning to standardize data in non-standard formats.
