What is Business Intelligence?

• Group of techniques/tools for gathering data from different sources
• Data consolidated in a data warehouse for analysis
• Example: Gathering sales data from various departments for visualization
• Data sources: SQL Server, SAP, Oracle, XML, CSV, etc.

Extract, Transform, Load (ETL)

• Four-stage process:
  1. Capture data from source systems
  2. Scrub and clean data
  3. Transform data as required
  4. Load data into the enterprise data warehouse
• Essential for business intelligence

Informatica PowerCenter

• Leading data integration tool
• Supports data migration, application integration, and data transformation
• Two categories of tools: Administrative and Development

Administrative Tools

• Repository Manager: Manages folders, users, and groups
• Administrative Console: Manages services, nodes, domain objects; performs administrative tasks

Development Tools

• Designer: Creates ETL mappings
• Workflow Manager: Creates and manages workflow to execute mappings
• Workflow Monitor: Monitors the execution status of workflows

Informatica PowerCenter Administrative Console

• Console for performing admin tasks
• Manages services and applications running on the domain
• Two essential services: Integration Service (performs data operations) and Repository Service (stores objects in the database)
• Manages security aspects like user roles and access

Demo: Informatica Tools

Objective

• Load retail organization's data and understand customers better
• Phases: Create folder in Repository Manager, create mapping in Designer, create workflow in Workflow Manager

Phase 1: Repository Manager

• Create a work folder for storing sources, targets, mappings, workflows
• Configure different repositories and analyze dependencies

Phase 2: PowerCenter Designer

• Source Analyzer Workspace: Import and manipulate source definitions
• Target Designer Workspace: Modify target definitions
• Mapping Designer Workspace: Define data flow and mappings
• Transformations: Joiner Transformation, Aggregator Transformation, etc.

Phase 3: Workflow Manager

• Create workflow and sessions/tasks to execute mappings
• Set session properties for source connections and target definitions
• Workflow Monitor: Monitors execution status and statistics
