Study Notes

BI Portals

Portals should be user-friendly and not overly complex to prevent user confusion.
Regular updates are essential for maintaining portal relevance and accuracy.
Interactivity is important to enhance user engagement and functionality.
Scalability and customization allow users to tailor the portal experience to their needs.
Users should perceive Business Intelligence (BI) applications as valuable resources.
The BI market comprises independent “pure-play” vendors and consolidated “megavendors” due to recent acquisitions.
Specific sectors, such as banking and healthcare, have unique BI system considerations to ensure compliance and data protection.
Businesses generate vast unstructured data (emails, memos, reports) that is often underutilized, with workers spending significant time managing this data.

Data Management

Unstructured data lacks predictable structure and is challenging to search, complicating data analysis and decision-making.
Data Warehouse Appliances combine hardware and software specifically designed for analytical processing, streamlining data-related tasks executed by Database Administrators (DBAs).
Mobile Business Intelligence (MBI) is limited in vendor availability and integrates with existing BI architectures.

Application Areas

Various sectors utilize analytics, including algorithmic trading, fraud detection, customer relationship management, and operational intelligence.
Other applications include dynamic pricing, supply chain optimization, and real-time monitoring across multiple industries.

Business Analytics

Focuses on continuous exploration of business performance through data analysis, aiming to enhance business planning.
Distinct from traditional business intelligence, which primarily deals with historical metrics and performance measurement.
Employs statistical methods, including predictive modeling and fact-based management to inform decision-making.

Learning Analytics

Draws techniques from multiple domains: statistics, business intelligence, web analytics, operational research, artificial intelligence, data mining, and social network analysis.
Emphasizes information visualization, allowing for a clearer understanding of data analytics.

Analytic Methods

Content analysis involves evaluating student-generated resources like essays.
Discourse analytics focuses on analyzing language used in student interactions.
Social Learning Analytics explore the impact of social interactions on learning processes.
Predictive analytics aim to identify at-risk students, provide personalized learning pathways, and support educational interventions.

Ethics & Privacy

Critical concerns include data ownership, communication transparency, and the role of human oversight in analysis systems.
Issues surrounding data sharing and trust in data among stakeholders are significant in the discussion of learning analytics.

Open Learning Analytics

Aims to enhance effectiveness in lifelong learning environments by adopting a diverse approach based on an analytics reference model.

Predictive Analytics

Encompasses statistical techniques for modeling relationships among variables to forecast future events.
Linear Regression involves predicting a dependent variable based on multiple independent variables.
Discrete Choice Models address scenarios where dependent variables are categorical rather than continuous.
Logistic Regression is utilized for binary outcome variables, transforming them into continuous predictions.
Multinomial Logistic Regression extends binary methods to cases with multiple categories without an implied order, maintaining data richness.
