Study Notes

Business Intelligence (BI)

BI is a set of processes, technologies, and tools used to transform data into actionable information and knowledge, driving profitable business decisions.
BI includes data warehousing, business analytics, and knowledge management.

Challenges in Building BI Solutions

Data exists in multiple, disparate locations.
Data formats may not be consistent or suitable for complex analysis.
Different roles (executives, analysts, line workers) have varying data needs.
Determining which data to analyze and the level of detail needed is crucial.
Understanding how users will interact with the data is essential.

Data Consolidation

Consolidating data involves moving, standardizing, and cleaning data to ensure consistency.

Extraction, Transformation, and Loading (ETL)

ETL is a crucial process for data warehousing and BI processes.
It extracts data from various source systems, transforms it to ensure consistency and improve quality, and loads it into a data repository.
ETL processes often consume a substantial amount of development time (up to 80%).

Business Issues with Data Consolidation

Business users need to define the data required for the data warehouse.
Addressing inconsistent data formats and structures.
Handling various data types (e.g., currency conversions).

BI Users

Executives/Decision Makers: High-level overview of business performance; limited analysis needed.
Analysts: Perform complex, detailed data analysis.
Information Workers: Need static reports or limited analytic power
Line Workers: Receive BI information as part of their job; no in-depth analysis needed.

Components of a Data Warehouse

Cubes: Data storage structures.
Measures: Numeric values (e.g., sales, profit)
Key Performance Indicators (KPIs): Measure performance
Dimensions: Context for data (e.g., time, geography, product).
Attributes: Specific elements within dimensions (e.g., Month, Region, product).
Hierarchies: Structures attributes for deeper analysis (e.g., Year -> Quarter -> Month).

Asking BI Questions

Humans often think in a multidimensional way.
"What" is the measure; "How" includes dimensions (e.g., sales by month, product, region)

Advantages of Data Warehousing

Maintains consistent and accurate data.
Provides a comprehensive view of business data.
Enables identification of trends and patterns.
Supports improved decision-making.
Speeds up access to information.
Reduces the overall cost of data analysis.

Summary of ETL and BI

ETL extracts, transforms, and loads data to the data warehouse or data mart.
BI reports and dashboards display data as measures and KPIs viewed across dimensions.

KPIs Examples (Key Performance Indicators)

Inventory accuracy
Receiving efficiency
Picking and packing cost
Inventory Turnover
Customer cycle order time
