Chapter 10: The REA Approach to Database Modeling Flashcards
User View
set of data that a particular user needs to achieve his or her assigned tasks
Semantic Models
Frameworks for designing accounting information systems that support multiple user views, capture operational meaning of user’s data and provides concise description of it
REA model/diagram
accounting framework for modeling an organization’s resources, events, and agents and the relationships between them
Resources
things of economic value to the organization (assets)
Economic Events
phenomena that effect changes (increases or decreases) in resources as represented by stock flow relation
Support events
include control, planning, and management activities that are related to economic events but do not directly effect a change in resources
Agents (internal and external)
individuals and departments that participate in economic and support events
Duality
each economic event is mirrored by an associated economic event in the opposite direction, give and receive event
Give event
decreases the economic resources
Receive event
increases the economic resources
View modeling
Database designer identifies and models the set of data that individual users need to make a decision or perform a task
Value chain
activities that use cash to obtain resources and then employ those resources to earn new revenues
View integration
combining the data needs of all users into a single schema or enterprise-wide view (consolidate individual models, define primary keys, foreign keys, and attributes, and construct the physical database and produce user views)
Value chain analysis
ability of organization to look beyond itself and maximize its ability to create value
