Information Architecture - The bridge between Business and IT
I'm modeling information architecture in three levels: conceptual, Logical and Physical. Conceptual information modeling is an effort to collect the main information types (something like subject areas) which is used by the business in order to reach enterprise's goals and objectives. Conceptual information example could be a Customer or Settlement. Logical data modeling is an effort to break conceptual information into logical entities. Each entity resemble set of data that is used by the business as one unit. Logical modeling also include capturing relations between entities and setting non-functional attributes for each entity (availability, security, Audit and control, Availability, backup, etc'). Physical modeling includes databases schemas and the relations between physical tables and logical entities.
