Understanding Business Intelligence
Business intelligence (BI) is a broad category of application programs and technologies
for gathering, storing, analyzing, and providing access to data to help enterprise users make
better business decisions.
BI applications include the activities of decision support, query and reporting, online
analytical processing (OLAP), statistical analysis, forecasting, and data mining.

Cont. BI Architecture - Source Systems
Process real-time transactions
Contain data structures optimized for modifications(inserts).
Usually provide limited decision support
Are commonly referred to as:
• Online transaction processing (OLTP) systems
• Operational systems
Examples of source systems could be flat files, Excel files ,External systems , CRM ,
ERP, or RDMS

Cont. BI Architecture - Data Staging Area
The different source data that comprise the company's business information need to
eventually be stored in a data warehouse. There is a process called Extract Transform
and Load (ETL) that facilitates means of formatting data from different sources so that
they can be loaded into a data warehouse structure.

Cont. BI Architecture - Date Warehouse
The varying forms of data get stored in a Data Warehouse. The Data Warehouse is the
structure that facilitates the main work of business intelligence - reporting and analysis.
The data warehouse can be architected according to schema (star, snowflake, etc), data
composition (values and attributes) and dimension levels, and descriptors. Data marts
enable additional segmentation within a broader data warehouse environment.

Concepts
• Business Intelligence
– Organisation-wide perspective
– Combining data from diverse systems
– High level aggregation to detailed drill-down
• Relational data not designed for BI
– Narrow focus on specific business requirement
– OLTP for speed of entry and integrity
– OLAP (On-line Analytical Processing) for aggregating large
data volumes

Core Processes
• ELT (Extract, Load, Transform)
– Import, clean and combine diverse data
– Store in Data Warehouse
• Star Schema
– Relational structure for OLAP, not OLTP
• Cubes
– Pre-aggregate results (sum, count)
• Reporting
• (Data Mining and Prediction)
