This document discusses key aspects of business intelligence architecture. It covers topics like data modeling, data integration, data warehousing, sizing methodologies, data flows, and new BI architecture trends. Specifically, it provides information on: - Data modeling approaches including OLTP and OLAP models with star schemas and dimension tables. - ETL processes like extraction, transformation, and loading of data. - Types of data warehousing solutions including appliances and SQL databases. - Methodologies for sizing different components like databases, servers, users. - Diagrams of data flows from source systems into staging, data warehouse and marts. - New BI architecture designs that integrate compute and storage.

DATA FLOWS DIAGRAM

15. 15 Business Intelligence Architecture
• Software (e.g. Oracle DB , Sybase DB, DB2, MS SQL Server…)
• Raw data are the data sources resulting from the operational
systems (e.g. CRM, RH, Billing, Purchases, SCM...)
• Usable data are raw data, indexes, aggregates, metadata,
dimensions, indicators and data work
• The database is structured on 3 levels
- Staging Area for data validation
- Data Warehouse for data reference
- Data Marts (cubes) for data analytics
DATA VOLUME QUALIFICATION

16. 16 Business Intelligence Architecture
• Software (e.g. SAP BO Explorer, Oracle BI, SAS analytics…)
• Number of users have access to BI system (named users)
• Number of users have access to BI system simultaneously
(concurrent users)
• Users are classified by typology
- Low users view predefined and static reports
- Medium users navigate within reports, do slicing and dicing, but
usually hit aggregates
- High users run ad-hoc queries with a high probability of full table
scans
• Operational period (e.g. from Monday to Friday)
• Time range (e.g. 08:00 AM - 07:00 PM)
USERS QUALIFICATION

17. 17 Business Intelligence Architecture
• Software (e.g. Oracle Data Integrator, PowerCenter
Informatica…)
• ETL processing are classified by typology
- Simple processing represents simple calculations and
concatenations
- Medium processing represents average calculations, medium
concatenations
- High processing represents heavy calculations, statistical, complex
algorithms and heavy concatenations
• Data retention duration (e.g. year, month, day)
• Operational period (e.g. from Monday to Friday)
• Operation frequency (e.g. daily, weekly, monthly)
• Time range (e.g. 08:00 PM to 06:00 AM)
