When creating a partition policy, you define how records of a table are stored in the table partitions in a database. You can create conditions for the records using the Partition Policy Details page. For example, if you create a partition policy, Salary_Partition, on the column, salary, that stores all the salary details in the table, Employee, then, in the Partition Policy Details page, you can define that only when the salary is less than or equal to 5000, the record be stored in the partition, partition1, and when the salary is more than 5000, it be stored in partition2.
