Study Notes
Introduction to Business Analytics
- Business analytics employs data and statistical methods to guide business decision-making.
- Utilizes relational database management systems (RDBMS) for data performance and management.
Importance of Business Analytics in Modern Business
- Data-Driven Decision Making: Enhances decision accuracy using data insights.
- Competitive Advantage: Offers insights that lead to better market positioning.
- Customer Understanding and Personalization: Tailors services/product offerings based on customer data.
- Operational Efficiency: Streamlines processes through data analysis.
Objectives of Business Analytics
- Focuses on improving decision-making, efficiency, revenue growth, and aligning strategic operational goals.
Metadata
- Provides crucial information about data, including definitions, sources, data types, and transformation rules.
- Aids users in understanding and navigating data within warehouses.
Data Marts
- Subsets of data warehouses designed for specific business units (e.g., marketing, finance, sales).
OLAP (Online Analytical Processing) Tools
- Enable complex queries and analysis of data from data warehouses.
- Support multidimensional analysis, allowing users to investigate data across various dimensions.
Data Sources
- POS Systems: Track daily sales transactions, customer purchases, and payment methods.
- CRM Systems: Maintain customer profiles and interaction histories.
- Inventory Management Systems: Monitor stock levels, orders, and supplier data.
- Online Sales Platforms: Capture online transactions, customer behavior, and website traffic.
Data Warehousing
- Involves collecting, storing, and managing large data volumes from diverse sources in a unified repository (data warehouse).
- The primary goal is to consolidate data for comprehensive reporting and analysis.
ETL Process
- ETL stands for Extract, Transform, Load; used to prepare data for warehousing.
- Data is extracted from various sources, transformed into a consistent format, and loaded into the data warehouse.
Key Characteristics of a Data Warehouse
- Subject-Oriented: Organized around key subjects (e.g., customers, sales) rather than routine operations for simplified data access.
- Integrated: Ensures consistency across data sources (databases, spreadsheets) through standardized formats.
Data Warehouse Database
- Centralized data warehouse database designed for complex queries.
- Stores tables related to sales, customers, products, inventory, and suppliers.
OLAP Tools and Analysis
- Used for dynamic analysis, such as sales trends across different dimensions like region and store.
