Question

BlackTom AI · Accepted Answer

The question asks: 'A design tool which describes the characteristics of each field in a table is known as'.

Given answer indicates: 'c. a data dictionary.'

Explanation of the correct concept:
- A data dictionary is a centralized repository that documents the metadata about data structures within a database. It typically includes information about each field (column) in a table, such as the field name, data type, size/length, nullability, default values, allowed values or domains, and any constraints (like primary keys or foreign keys).
- This metadata helps designers and developers understand the schema, enforce data integrity, and communicate the data model across teams.

Notes on the absence of other options:
- The provided information does not include other answer choices, so it isn’t possible to analyze why the alternatives are incorrect. In a typical scenario, other options might refer to terms like schema, data model, data catalog, or glossary, which have related but distinct meanings. A data dictionary is specifically the collection of field-level characteristics and constraints, which supports detailed understanding of each column.

In summary, describing the characteristics of each field in a table is the role of a data dictionary, making option c the appropriate choice given the prompt.
