Quick Answer
The hierarchical database model is the correct choice for storing an organizational chart because it naturally represents parent-child relationships, such as manager-subordinate reporting lines, in a tree-like structure. This model allows each record to have a single parent and multiple children, directly mirroring the one-to-many relationships found in a reporting hierarchy. On the CompTIA ITF+ FC0-U61 exam, this concept tests your understanding of how different database models map to real-world structures; a common trap is confusing the hierarchical model with the network model, which allows many-to-many relationships. To remember it, think of a family tree: each node has one parent above and can have many children below, just like an org chart.
This FC0-U61 practice question tests your understanding of database fundamentals. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company needs to store an organizational chart showing reporting relationships. Which database model is most appropriate?
Relational
Why wrong: Relational can model hierarchy but is not the most appropriate.
Document
Why wrong: Document databases store JSON-like documents.
Graph
Why wrong: Graph databases excel at complex relationships.
Hierarchical
Hierarchical databases are optimized for parent-child relationships.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Hierarchical
A hierarchical database model is most appropriate for storing an organizational chart because it naturally represents parent-child relationships, such as manager-subordinate reporting lines, in a tree-like structure. This model allows each record to have a single parent and multiple children, directly mirroring the one-to-many relationships in a reporting hierarchy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Relational
Why it's wrong here
Relational can model hierarchy but is not the most appropriate.
Document
Why it's wrong here
Document databases store JSON-like documents.
Graph
Why it's wrong here
Graph databases excel at complex relationships.
Hierarchical
Why this is correct
Hierarchical databases are optimized for parent-child relationships.

Common exam traps
The trap here is that candidates often choose 'Relational' because it is the most common model, but they overlook that hierarchical databases are specifically designed for strict parent-child structures like org charts, whereas relational databases require cumbersome recursive queries.
Detailed technical explanation
In a hierarchical database, records are organized as segments in a tree, with each child segment having a single parent segment, accessed via pointers. For example, IBM's Information Management System (IMS) uses DL/I calls to navigate from a root segment (e.g., CEO) down to dependent segments (e.g., VPs, managers). This model enforces referential integrity through physical adjacency, making traversal fast but rigid for structural changes.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
