Mandy Chessell commented on ATLAS-2139:
---------------------------------------
It seems you have picked up many of the key parts.
Many relationships are linked to either Asset, or Referenceable. Referenceable
adds an attribute called qualifiedName and Asset inherits from it adding name
(which is more of a display name). Host and SoftwareServer inherit from
ITInfrastructure which inherits Infrastructure which inherits from Asset.
DataStore also inherits from Asset.
A database is a DataStore with the Database classification. The Database
classification allows you to add the DB type.
Schemas are associated with assets though the AssetSchemaType relationship
(0503).
Relational columns and tables are related through the SchemaAttributeType and
AttributeSchemaType relationships (0505). I have added a picture to show this.
Connections are config properties for use by a connector connecting to the
Asset (eg database). There should be only one Asset connected to a Connection
(but an Asset May have multiple Connections for different protocols etc.)
