Difficulty: Easy
Correct Answer: fields
Explanation:
Introduction / Context:
In data management and database design, information is organized hierarchically: databases contain tables (or files), tables contain records (or rows), and records contain fields (or columns/attributes). Understanding this vocabulary is essential for schema design, form layout, reporting, and writing correct queries.
Given Data / Assumptions:
Concept / Approach:
A record is composed of fields. Each field stores a single data item or attribute value (such as customer_name or date_of_birth). Fields are defined by a name and a data type, may allow nulls, and can be constrained by keys or validations. This fine-grained structure enables indexing, filtering, and updates without touching unrelated data in the same record.
Step-by-Step Solution:
Verification / Alternative check:
Open any spreadsheet-like table view: each row (record) shows values under column headings; those columns correspond to fields. Similarly, in SQL, INSERT and SELECT reference column (field) names within a row (record).
Why Other Options Are Wrong:
Common Pitfalls:
Confusing “record” with “file/table,” or using nonspecific terms like “data” that do not identify the structural unit required for schema design and constraints.
