Study Notes
Data Repositories and Business Intelligence Architectures
- The primary repository of data for business intelligence analysis is the data warehouse.
Decision Support Systems (DSS)
- The model management module in a DSS provides end-users with mathematical models derived from operations research, statistics, and financial analysis.
- The model management module assists knowledge workers in a DSS by enabling them to build, store, and manage mathematical models.
Decision-Making Process
- A decision should abide by ethical standards, in addition to being compliant with the law.
- During the exclusion stage, decision-makers identify and eliminate unsuitable options.
- The main purpose of evaluating feasible alternatives is to select the best option.
- A decision may be unworkable despite being ideal from economic, legal, and social standpoints due to feasibility issues.
- A decision maker should assess the decision's impact on the organization, besides economic, legal, and social factors.
- The major methodological reference proposed in the early 1960s regarding the decision-making process is the rational model.
Mathematical Models
- One advantage of adopting mathematical models in the decision-making process is that they enhance knowledge preservation within an organization.
- Building a mathematical model contributes to knowledge preservation by allowing knowledge workers to document and share their knowledge.
Business Intelligence Systems Architecture
- The primary task related to data sources in a business intelligence system architecture is to integrate data from various sources.
- Data integration techniques include data federation, ETL (Extract, Transform, Load), and data virtualization.
- Correcting data in a data warehouse affects business intelligence systems by ensuring data quality and reliability.
- Typical data sources in a business intelligence system architecture include OLTP (Online Transactional Processing) systems, external sources, and front-office systems.
- Complex queries for OLAP (Online Analytical Processing) analyses are directed to the data warehouse, not operational systems, to minimize the load on operational systems.
Data Warehouse
- Physically separating the data warehouse from operational systems enhances system performance and improves data quality.
- Extending the time span of data in a data warehouse is important for analyzing trends and predicting future outcomes.
- Semantic homogeneity plays a crucial role in data integration within a data warehouse by ensuring consistency in data definitions and format.
Data Sources
- Data from back-office systems usually originates from transactional systems, such as ERP (Enterprise Resource Planning) systems.
- Data originating from call-center activities and customer assistance comes from CRM (Customer Relationship Management) systems.
- Geographic information systems (GIS) provide spatial data as a significant source of external data.
- Front-office systems typically include data from sales, marketing, and customer-facing activities.
- External sources like agencies provide demographic, economic, and environmental data to extend internal databases.
- Back-office systems primarily focus on internal operations, whereas front-office systems focus on customer-facing activities.
