The data model produced by reverse engineering is a(n) ________.

Question

BlackTom AI · Accepted Answer

The question asks about the data model produced by reverse engineering. 
Option 1: conceptual schema. A conceptual schema is a high-level data model that describes the overall structure of the data independent of a specific database implementation, typically created during the design phase, not the result of reverse engineering. 
Option 2: internal schema. The internal schema refers to the physical-level organization of data, such as file structures and indexes, which is more about storage details than a readable data model produced by reverse engineering. 
Option 3: dependency graph. A dependency graph shows relationships of dependencies between elements (like modules or computations) and is not a standard representation of a data model produced from reverse engineering of a database. 
Option 4: table-relationship diagram. This option aligns with what reverse engineering typically yields: a diagram that maps tables (relations) and their relationships (foreign keys, connections) to reflect the actual database schema. 
Thus, the most fitting choice is the diagram that explicitly conveys tables and their interconnections, i.e., the table-relationship diagram.
