What concept is primarily focused on in a declarative query?

In the context of a declarative query, the primary focus is on specifying what actions need to be taken with the data, rather than detailing how those actions should be performed. Declarative queries allow users to describe the desired outcome or the expected result of the query, such as retrieving specific information from a database.

For instance, in SQL (Structured Query Language), a declarative query like “SELECT name FROM employees WHERE department = 'Sales'” informs the database management system about the desired data (names of employees in the Sales department) without outlining the step-by-step process for how to fetch that data. This abstraction makes it easier for users to interact with complex datasets without needing in-depth knowledge of the underlying algorithms or data retrieval methods.

Understanding this concept is essential for working effectively with database management systems and for creating efficient queries that provide the desired results promptly.
