What are the five rows in the original ISA framework?

Scope
Enterprise or business model
System model
Technology model
Components

- Data – what entities are involved

- Function – the functions performed
- Network – the locations and interconnections

What are E-R diagrams?

What are the rules of the framework?

1. The columns have no order.
2. Each column has a simple, basic model
3. The basic model of each column must be unique
4. Each row represents a distinct, unique perspective
5. Each cell is unique
6. The composite or integration of all cell models in one row constitutes a complete model from the perspective of that row.
7. The logic is recursive
