Solution

Break Down the Problem

  1. Identify the key components of the question: ERD (Entity-Relationship Diagram), entities, attributes, and their representation in a table format.
  2. Understand the terminologies being used in the options provided.

Relevant Concepts

  1. In a database, an entity is represented as a table.
  2. The attributes of an entity correspond to columns of that table.

Analysis and Detail

  1. Cells: These are the individual data points that are created by the intersection of rows and columns.
  2. Rows: Each row in a table represents a single record or instance of an entity, which encompasses all the attributes.
  3. Columns: Attributes of the entity become the columns in the table, each representing a particular property of the data stored in the rows.

Verify and Summarize

Analyzing the options:

  • Cells are individual data points, not attributes.
  • Rows represent records, not attributes.
  • Columns are directly derived from the attributes.

Thus, the attributes of an entity in an ERD become the columns in the corresponding table.

Final Answer

Columns.
