Study Notes
What is the Internet?
- A network of networks allowing communication across a wide range of devices
- The internet has its roots in the 1960s, initially created for government research
- The ARPANET was a precursor to the internet, using a new communication protocol called TCP/IP to enable different networks to communicate
- The World Wide Web (WWW) is a collection of information organized as Web pages containing text and images.
How to Access the Internet?
- Many schools and businesses have direct access to the internet using special high-speed communication lines.
- You can use an Internet Service Provider (ISP) to access the internet.
Client/Server Structure of the Web
- Web servers are computers located worldwide that store the files that make up the web.
- Web clients are the devices that connect to the internet and use web browsers to access web servers.
Internet Protocol (IP) Addressing
- Each computer on the internet has a unique IP address, a four-part number.
Business Intelligence (BI)
- A collection of methods, processes, and technologies used to transform raw data into useful information for making better decisions.
- BI involves data collection, analysis, and visualization
- Common Data Problems in BI include:
- Structured, unstructured, and semi-structured data
- Information overloading
- Big data
- Difficulty accessing data
- Lack of data
Decision Making in BI
- Decisions can be made based on:
- Facts or data
- Simulation (models)
- Intuition
- Group negotiation
- BI is often considered a Decision Support System (DSS)
Evolution of BI
- BI has evolved from early systems like Executive Information Systems (EIS) and Decision Support Systems (DSS) in the 1980s.
- The concept of data warehousing, business intelligence, and dashboards emerged in the 1990s and 2000s.
- The 2010s saw a shift towards analytics, big data, data science, and augmented business intelligence.
Analytics in BI
- Analytics is a broader term for data analysis, often referring to a more systematic and automated process.
- While analytics can be part of BI, some consider it to be more encompassing, extending beyond traditional BI.
BI/Analytics: A General Process
- In general, BI/analytics involves collecting data, cleaning and transforming it, analyzing it, and then visualizing the results to drive insights and decision-making.
BI Systems and Platforms
- A BI system is a computer information system that implements BI capabilities and processes.
- Enterprise-level BI systems emphasize control and performance.
- Basic Techniques in Business Analytics:
- Regression
- Forecasting
- Correlation
- Factor analysis
Data Visualization
- Data visualization is thegraphical representation of data for better perception and understanding.
Reports
- A report presents detailed data in a structured format, typically in tables and with numbers and text.
- Modern reports can be interactive and visual but still focus on detailed data.
Dashboard
- A dashboard provides a consolidated, visual display of important data and information on a single screen for a quick overview.
- Elements of a dashboard include data, visuals, and a user interface.
The Modern/New BI
- Modern BI platforms are designed for IT-enabled analytic content development.
- They emphasize agility and flexibility, allowing for easier access to analytics capabilities without needing upfront data modelling.
