威尼斯人娱乐场 Catalog Data Model
What is the 威尼斯人娱乐场 Catalog Model?
The 威尼斯人娱乐场 Catalog model shows you the hierarchy or relationships between catalog descriptions and their creators. The hierarchy involves a 'parent/child' relationship between records. For example, a series can be the parent of several items and a series can also be the child of a specific collection or record group.
The relationships between archival descriptions in the 威尼斯人娱乐场 Catalog are as follows:
- The creator is responsible for creation or maintenance of a series of materials.
- A series belongs to a record group or a collection.
- A file unit belongs to a series.
- An item can belong to a file unit or belong directly to a series.
- Series, file units, and items only have one parent record.
- Collections, record groups, series, and file units can have multiple child records.
