A database administrator is optimizing a dataset where each row represents a research paper and contains 18 fields. If each field averages 25 bytes and there are 4000 rows, how many kilobytes does the dataset occupy?

**The growing need to streamline research data: How a database administrator shapes smarter datasets** As academic research accelerates, the scale and complexity of data repositories are expanding beyond traditional tools. From medical studies to social science analyses, a single repository can track thousands of research papers, each with structured metadata—authors, publication dates, keywords, and experimental parameters. At the heart of this transformation is the database administrator, whose work quietly powers the integrity and performance of research datasets. One frequently asked technical question reveals the tangible impact of their role: *How many kilobytes does a dataset containing 4,000 rows—each with 18 fields averaging 25 bytes—actually occupy?* ### The Size of Data That Shapes Research Working with real-world research datasets, a database administrator evaluates storage efficiency to maintain speed and accessibility. A standard row tracking a research paper includes critical yet compact fields: title, authors, abstract, publication date, keywords, and identifiers. With 4,000 rows and 18 average fields per row, the total byte count becomes approximately 1.8 megabytes—based on 25 bytes per field. That’s around 1,800,000 bytes. To convert to kilobytes, simply divide by 1,000—yielding roughly 1,800 kilobytes. This efficient sizing ensures fast querying, smooth integration into analytical pipelines, and lower long-term storage costs.
