Area 5 Models - Schema, Models and Reference Data¶
Area 5 is where standards are established. This includes data models, schema fragments and reference data that are used to assist developers and architects in using best practice data structures and valid values as they develop new capability around the data assets.
The first set of models describe the structure of data as it is deployed. These models describe the abstract definition of structured data.
- 0501 Schema Elements
- 0505 Schema Attributes
- 0507 External Schema Types
- 0511 Map Schema Element
- 0512 Derived Schema Elements
These next models show how the schema is attached to assets and ports on a process.
This next model provides the ability to capture a template for generating schema artifacts for direct inclusion in an implementation.
The next set of models are specializations of the abstract schema elements described aimed at different types of technology.
- 0530 Tabular Schema
- 0531 Document Schemas
- 0532 Object Schemas
- 0533 Graph Schema
- 0534 Relational Schema
- 0535 Event Schema
- 0536 API Schemas
- 0537 Display Schemas
Data value specification describe the characteristics of data values. For example, the data class specifies logical types of data - such as data, address, credit card, social security number. A data grain identifies the granularity of a row/object.
Reference data describes standard sets of data values - such as a list of country codes.
Instance metadata identifies schema attributes that contain metadata, rather than business data.
The next set of models describe the content of different types of data models
The next set of modes are for the specification of data structures.
The final set of models capture architectures and patterns.
