Study Notes
Introduction to Business Intelligence
- Business intelligence (BI) helps organizations make better decisions.
- BI uses data to improve performance and optimize decision-making.
Definition of Business Intelligence
- Business intelligence includes applications, infrastructure, tools and best practices to access and analyze data for decision-making.
- BI is the process of gathering, transforming, and analyzing raw data to create useful information for strategic, tactical, and operational insights.
- The term "business" encompasses commercial entities, organizations, functional areas or domains, non-profit organizations, governments, and individuals.
Why Build a BI System?
- Businesses need to access and analyze the information they gather.
- BI systems provide access to data, improve information quality, integrate data from different systems, define common information, and access historical data.
- Challenges include understanding user needs, ensuring data integrity, managing data feed costs, defining project scope, maintaining system performance, and ensuring common management rules.
The DIKW Pyramid
- DIKW stands for data, information, knowledge, and wisdom.
- Data: Unprocessed, raw facts. It does not support decision-making.
- Information: Interpreted data with meaning. It helps managers make decisions.
- Knowledge: Information understood through experience, ideas, values, and opinions.
- Wisdom: Discernment on content and common sense judgment. It enables action to adapt the organization, people, processes, and tools.
Operational Data vs. Decision Data
- Operational data is detailed, real-time data used for day-to-day operations. It is structured for IT professionals.
- Decision support data is aggregated, historical data used for decision-making. It is structured for managers and analysts.
Data Storage in BI Systems
- Operational Data Store (ODS): Subject-oriented, volatile data used for specific decision-making processes. It provides a real-time view of one or more operating systems.
- Data warehouse: Subject-oriented, integrated, non-volatile historical data used for decision-support.
- Data mart: Subject-oriented, non-volatile data store targeted to a specific business topic or area.
- Data mining: Tools and technologies used to find trends, segment information, and discover correlations.
Data Warehouse vs. Data Mart
- Data warehouse: Corporate data repository that combines multiple data marts, ensures data integrity across different marts, and contains all necessary measures and dimensions.
- Data mart: A set of specific dimensions and measures used for specific business topics.
DBMS and Data Warehouse
- DBMS and data warehouse have different goals, store different data types, use different queries, and have different data models.
- DBMS (Database Management System): Used for transactional processing (OLTP), inserting, modifying, and efficiently querying information.
- Data warehouse: Used for analytical processing (OLAP) and storing data for decision-making.
What Data Warehouse Allows Organizations to Achieve
- Centralized data management and accessibility
- Efficient data integration
- Historical trends analysis
- Advanced business intelligence
- Informed decision making
- Enhanced customer understanding
- Optimized operational efficiency
- Predictive analytics
- Cross-functional insights
- Compliance and security
Data Warehouse Definition
- A data warehouse is a copy of transaction data specifically structured for query and analysis.
