Prioritizing based on impact and urgency ensures the most critical issues receive attention first while maintaining progress on other goals.

Outcome-based performance indicators directly measure whether the program is achieving its intended results and goals.

Second Normal Form (2NF) addresses the issue of partial dependencies, which occur when a non-key attribute is dependent on only a part of a composite primary key. To achieve 2NF, these partially dependent attributes are moved to a new table with the relevant part of the composite key as its primary key. This process reduces data redundancy and improves data integrity within the database.

The `DISTINCT` keyword in SQL is specifically used with the `SELECT` statement to retrieve only unique rows from a query result. It effectively eliminates any duplicate entries, ensuring that each returned row is unique based on the selected columns. Other clauses like `GROUP BY` are for aggregation, and `ORDER BY` is for sorting, not for removing duplicates.

Evidence-based decision making uses data and research to improve the accuracy of decisions and reduce the influence of personal bias.

A view is a stored SELECT query that acts as a virtual table; it does not store data itself but derives results from underlying tables each time it is queried.
