Which metrics indicate data quality in OIMS?

• A. Latency, error rates, throughput, and uptime.
• B. Completeness, accuracy, consistency, timeliness.
• C. Completeness, accuracy, consistency, timeliness, validity, and uniqueness.
• D. Data retention, access frequency, user satisfaction, and downtime.

Answer: (C)

Data quality in OIMS is assessed by dimensions that describe how trustworthy and usable the data are for decision-making. The strongest set includes completeness, accuracy, consistency, timeliness, validity, and uniqueness. Completeness means all required fields are populated so nothing essential is missing. Accuracy ensures the recorded information reflects reality, such as correct offender details and offenses. Consistency means data matches across different parts of the system and over time, with standardized formats and codes. Timeliness focuses on data being current and up-to-date so decisions are based on the latest information. Validity checks that values conform to defined rules and allowed ranges or codes, ensuring data entries are reasonable and categorized correctly. Uniqueness ensures there are no duplicate records for the same entity, preventing confusion and conflicting information. These six together cover both the content and structure of data, which is why they’re the best indicators of data quality in OIMS. Metrics like latency, error rates, throughput, and uptime describe how the system performs and how quickly data can be accessed, but they don’t measure the quality or trustworthiness of the data itself. Similarly, data retention, access frequency, user satisfaction, and downtime relate to governance, usage, and availability rather than the inherent quality of the data. A set that includes completeness, accuracy, consistency, timeliness, validity, and uniqueness provides the most comprehensive view of data quality.
