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.
