Business Intelligence och Analytics Översikt

• This document provides an overview of business intelligence (BI) and analytics.

Introduction to Business Intelligence and Analytics

• BI transforms data into actionable information, informing an organization's strategic and tactical business decisions.
• Analytics is the extensive use of data, statistical and quantitative analysis, explanatory and predictive modeling, and fact-based management to drive decisions and actions.
• BI answers what happened, what is happening, and what will happen, while analytics provides insight and action.
• BI and analytics tools and techniques are used to make better and faster decisions.

Evolution of Business Intelligence

• The evolution of BI includes several stages, starting with reporting and static reports.
• Evolution continued with executive information systems (EIS), which provided summarized information to executives.
• Data warehousing enabled the storage and analysis of large volumes of data.
• OLAP (Online Analytical Processing) allowed for multidimensional analysis of data.
• Business intelligence dashboards provided a visual overview of key performance indicators (KPIs).
• Predictive analytics forecasts future outcomes based on historical data, and real-time BI delivers up-to-the-minute insights.

The Business Intelligence Value Chain

• The BI value chain consists of stages: data sources, data extraction, data storage, data analysis, and knowledge.
• Data sources include transaction databases, enterprise resource planning (ERP) systems, customer relationship management (CRM) systems, and external data.
• Data extraction involves collecting data from various sources.
• Data storage requires the creation of a data warehouse or data mart.
• Data analysis involves using BI tools and techniques to analyze the data.
• Knowledge involves transforming the analyzed data into actionable insights.

Business Intelligence Users

• Different users within an organization have different BI needs.
• Executives need high-level dashboards to monitor KPIs.
• Managers need detailed reports to track performance and identify problems.
• Analysts need tools to perform in-depth data analysis.
• Operational staff need real-time information to make day-to-day decisions.

Business Intelligence Applications

• Big data analytics involves analyzing large volumes of data from various sources.
• Artificial intelligence (AI) is being used to automate data analysis and provide more insights.
• Self-service BI empowers users to perform their own data analysis.

Data Governance and Data Quality

• Data governance and data quality are crucial for successful BI implementation.
• Data governance involves establishing policies and procedures for managing data.
• Data quality ensures that data is accurate, complete, and consistent.
• Data profiling is used to assess the quality of data.
• Data cleansing involves correcting errors and inconsistencies in the data.

Data Warehousing

• Data warehousing is an architecture for storing and analyzing large volumes of data.
• A data warehouse is a central repository of integrated data from multiple sources.
• Data marts are subsets of a data warehouse that are specific to a particular business function.
• ETL (Extraction, Transformation, and Loading) processes are used to extract data from various sources, transform it into a consistent format, and load it into the data warehouse.
• Data modeling involves designing the structure of the data warehouse.

Data Mining

• Data mining is the process of discovering patterns and relationships in large datasets.
• Association rule mining identifies relationships between items.
• Classification is used to categorize data into predefined classes.
• Clustering groups data points into clusters based on similarity.
• Regression analysis predicts a continuous value based on input variables.

Big Data Analytics

• Big data is characterized by volume, velocity, and variety.
• Big data analytics involves analyzing large volumes of data from various sources.
• Hadoop is a framework for storing and processing big data.
• Spark is a fast and general-purpose cluster computing system.
• NoSQL databases are used to store unstructured and semi-structured data.

Text Mining

• Text mining extracts information from unstructured text data.
• Natural language processing (NLP) is used to understand the meaning of text.
• Sentiment analysis identifies the sentiment expressed in text.
• Topic modeling discovers the topics discussed in a collection of documents.

Web Analytics
