My data arrives and saved randomly to my owl file: These four values are the income of employee's four weeks so in week1, he earns 200, week2 300 week3 150 and week4 280.
I need some sorting in which I can describe if the Employee progresses each week according to his salary. If he earns like 150, 200, 280, 300, then for sure he progresses. Kindly if you described the required Jena rules here to accomplish this goal?
