Abstract
Creation of an information system for a linguistic center
Incoming article date: 18.03.2022The requirements for the creating information system automating the linguistic center activities are analyzed and optimized. The first and second stages of IP creation Life Cycle are presented. The analysis of the subject area and the design of the information system using the tools and methods of the object-oriented approach is carried out. Using such CASE tool, as the RationalRose, UML diagrams describing the activities of the Language Link linguistic center are constructed. By means of AnyLogic, simulation modeling was carried out and a student testing model was developed to determine the level of language proficiency in order to choose the exam category. The requirements for the projected information system of the linguistic center are formulated. Logical and physical ERD models of the database structure are constructed using the ERWin CASE tool. The design of the user interface of the information system for the linguistic center has been also carried out.
