Precise Requirement Changes Integrated System (PRICES) is a framework to develop a web-based product line. PRICES is designed based on model-driven engineering and delta-oriented programming. The goal of this tutorial is to introduce how PRICES can be used to model the problem domain and generate a running web application. The tutorial is planned to be conducted in a half-day. A combination of lecture and hands-on training will be provided. In addition, we will demonstrate a possibility of a semi-automatic approach to generate a web application using SPLE. Participants can try to develop a new variation and generate an application using a running case study. © 2021 ACM.
