MODELING APPROACH FOR CRUDE OIL PRICE PREDICTION SYSTEM BASED ON UML

The purpose of this article is to present a method of analyzing and designing crude oil price prediction system, which can be used by both organizations and individuals. This article first analyzes the factors that influence international crude oil price, then integrates different methods of crude oil price prediction from different users into a single system using the formula template technique. During the process of analyzing and designing this system, UML (Unified Modeling Language) modeling techniques are used to greatly improve the quality of system analysis and design. In this part, we first discuss use case modeling, the basis for all the UML techniques. Next, we analyze how a use case is used to derive class diagrams and sequence diagrams, the most commonly used UML diagram.
