Chapter 3 Developing an enterprise arChiteCture A logical data model has three main elements:
1. Entities â Each entity represents a set of items
relevant to a business.
2. Relationships â Associations between entities.
3. Attributes â Attributes describe entities.
Given that entities describe items that are relevant to a business and relationships describe how theyâre associated within the context of the business, the logical data model creates a connection between business requirements and quality data structure.
Physical Data Model
Physical data models are not a must, but they may offer a useful starting point for the data architect. The data architect can use these models to deduce the logical data models and, consequently, the conceptual data models for baseline architectures. Even in scenarios when the information models were developed from the conceptual data model initially, going from the physical data model back up to the conceptual data model can be a means of double-checking the validity of the models.
The main outputs of this development process are
⢠Validated data principles
⢠Gap analysis results
⢠Impact analysis (areas where the Business Architecture
may need to adapt to accommodate the Data
Architecture)
It is important to note the importance of a robust data architecture in regard to maintaining data standards. Data is often exchanged with parties outside of the organization; standards that codify the way that data should be represented and transmitted between interested parties should be enforced.
