Question

BlackTom AI · Accepted Answer

The prompt asks for the design tool that identifies the characteristics of fields in each table, which points toward documentation or metadata about data structures.
Option a: 'an entity-relationship (ER) diagram.' ER diagrams model entities, their attributes, and relationships between entities, but they focus on structure and relationships rather than listing the detailed characteristics of every field across tables. This means ER diagrams are more about how data is connected than enumerating field-level metadata.
Option b: 'a layout diagram.' Layout diagrams are typically used for presenting the visual arrangement of components in a UI or page, not for detailing database field characteristics. This option describes a presentation or UI-oriented artifact, not a data dictionary.
Option c: 'a query design.' Query design refers to how queries are constructed to retrieve or manipulate data, including selection, projection, joins, and conditions. While a query design interacts with fields, it does not systematically identify the characteristics of fields across tables in a centralized metadata sense.
Option d: 'a data dictionary.' A data dictionary is specifically the repository of metadata that documents the attributes of data elements, including fields in each table such as names, data types, allowed values, sizes, and descriptions. This aligns exactly with identifying the characteristics of fields in each table.
In summary, the data dictionary is the authoritative source for field-level characteristics, whereas the other options describe artifacts that serve different purposes (modeling relationships, layout, or query construction) and do not systematically catalog field metadata.
