Which items are included in the data dictionary of a data store? i. Input and output flows ii. Source/Sink iii. Data Structure iv. Description

Question

BlackTom AI · Accepted Answer

Carefully listing what a data dictionary in a data store typically documents can help evaluate the options.
Option a: "i, iii" — This excludes iv (Description). Input and output flows (i) and Data Structure (iii) are commonly included, but a complete data dictionary also often includes descriptions of data elements and other metadata. Omitting Description (iv) makes this incomplete in many data dictionary definitions.
Option b: "ii, iv" — This includes Source/Sink (ii) and Description (iv). While descriptions are indeed part of metadata, Source/Sink is not typically a core item documented in the data dictionary itself; the dictionary usually describes the data elements rather than the job-level components like Source/Sink.
Option c: "i, iii, iv" — This includes Input and output flows (i), Data Structure (iii), and Description (iv). These three items collectively cover the flow context, the structure of the data, and narrative/descriptive metadata, which aligns with common practice for data dictionaries that describe data elements and their usage.
Option d: "i, ii, iii, iv" — This includes all items: i, ii, iii, and iv. While some frameworks might mention Source/Sink, it is not universally considered a core component of a data dictionary. Some definitions restrict the dictionary to the data elements and their descriptions and structures rather than process flow or external pipeline components.
Overall, options can be weighed by which items are generally considered standard components of a data dictionary: primary emphasis is on what the data is, how it is structured, and descriptive metadata. This typically corresponds to i, iii, and iv, while ii is often less central to the data dictionary content itself.
