Advanced Analytics in Oracle

 Advanced Analytics in Oracle

Oracle Database includes a range of advanced analytics features, including data mining, machine learning, and predictive analytics. These features allow users to analyze large amounts of data and extract insights and patterns that can be used to inform business decisions. Here is an example:

SELECT *

FROM (

   SELECT country_name, AVG(salary) AS avg_salary

   FROM employees e

   JOIN countries c ON e.country_id = c.country_id

   GROUP BY country_name

)

MODEL

   DIMENSION BY (country_name)

   MEASURES (avg_salary)

   RULES (

      avg_salary[ANY] = PREDICT(

         AVG_SALARY[CV(country_name)],

         avg_salary[CV(country_name)],

         country_name

      )

   );

This query uses the Oracle Database "MODEL" clause to perform predictive analytics on the "employees" and "countries" tables, predicting the average salary for each country based on the data in the tables.
