Business Data Model (Updated with Security Data)

Business Data Model

Business Data Model. It is not the task of a security architecture team to develop the Business Data Model itself, and so this is assumed to be a preexisting model to be updated with relevant security data.

Physical layer focus on data. this means that you are concerned with the physical organization and management of data so

that it supports information and knowledge at the higher architecture layers. This physical data management involves:

• File structures, including record structures and field structures
• File management tools, including directory management
• Databases structures
• Database management systems (DBMSs).
