Difficulty: Easy
Correct Answer: All of the above
Explanation:
Introduction / Context:
Spreadsheets are common sources and sinks for tabular data. Understanding their file formats and how they integrate with databases and visualization tools is practical for ETL and reporting workflows.
Given Data / Assumptions:
Concept / Approach:
While native formats may be binary (e.g., XLSX as a zipped package), spreadsheets commonly export flat files (CSV, TSV) that are ASCII/UTF-based and widely interoperable. Many DBMSs can use these via external tables or import utilities. Spreadsheets also include built-in capabilities to render charts and graphs from selected ranges.
Step-by-Step Solution:
Verification / Alternative check:
Common workflows: export CSV from Excel or Google Sheets; use COPY in PostgreSQL or SQL*Loader in Oracle; build charts within the spreadsheet UI.
Why Other Options Are Wrong:
Each individual statement is true; therefore ‘‘All of the above’’ best summarizes the capabilities.
Common Pitfalls:
Assuming binary-only storage; practical interchange almost always uses CSV/TSV for portability. Also, ‘‘direct’’ DBMS use may require an import or external table definition, but operationally this is treated as usable.
Final Answer:
All of the above
