When developing any information system, an extremely important stage of its life cycle is the design or modeling stage. Among the existing approaches to the design of information systems, such as, for example, the “classic” development of UML diagrams using a unified modeling language, the model-oriented systems engineering approach, focused on building models, is gaining popularity. Purpose of the study. Consider modeling a system for monitoring and analyzing electronic media information using the methods of model-oriented system engineering. Research methods and tools. It is proposed to use the toolkit of the system-oriented design methodology, focused on the creation and use of models of different degrees of detail at different stages of design. The application of models of hierarchical decomposition of entities is presented on the example of typical essential characteristics of artificial systems: requirements for the system, system functions, system components (subsystems), work on creating a system. A regular method for constructing and consistently expanding architectural models of products is described, on the basis of which models of hierarchical taxonomy of functional requirements for the system, key functions, and components of the system core are built. Based on hierarchical taxonomy models, a model for matching requirements and functions and a model for matching functions and system components are built. Results. The developed models clearly show the relationship of system components, requirements, functions and modules with each other. The approach used makes it possible to detail the presentation of the system based on its decomposition into subsystems and on the basis of taking into account the essential characteristics. All this makes it possible to streamline the sequence of stages of creating a system and decompose them into separate stages of work. Conclusion. The results obtained in the course of the conducted research make it possible to proceed to the next stage of the life cycle of the information system being developed – its software development.

System Acceptance

To increase users’ trust in the systems they use, there is a need to develop trustworthy systems. These systems must meet the needs of the system’s stakeholders with respect to security, privacy, reliability, and business integrity (Mundy, deVries, Haynes, & Corwine, 2002). The first major step in achieving trustworthiness is to properly and faithfully capture the stakeholders requirements. A requirement is something that the system must satisfy or a quality that the system must possess. A requirement is normally elicited from the system stakeholders, including its users, developers, and owners. Requirements should be specified before attempting to construct the system. If the correct requirements are not captured properly and faithfully, the correct system cannot be built. Consequently, the system will not be usable by its intended users. The success of any system depends on meeting requirements classified under two complementary types. First, the functional requirements are the system’s operations from the user’s perspective describing the visible and external interactions with the system under consideration. Second, the non-functional requirements (NFRs) are mainly the system’s constraints imposing special conditions and qualities on the system to construct. Consequently, system acceptance testing must be based on both functional and non-functional system’s requirements. Unfortunately, it is reported that about 60% of errors originate from the requirements and analysis activities (Weinberg, 1997). Surveys have shown that large numbers of IT-based systems were implemented starting from their elicited functional requirements without a clear and formal consideration of their non-functional counterparts such as security requirements. Furthermore, system requirements engineers and analysts are not well-trained in capturing security requirements early in the system development process. Security assurances are often based on the traditional and ad hoc approach of conducting penetration tests followed by a patching process. This approach is very costly and endangers the fulfillment of the basic goals of system security, namely confidentiality, integrity, availability, and accountability. Recently, many researchers addressed security requirements engineering as an integral and essential element of systems engineering. Devanbu and Stubblebine (2000) propose a roadmap for software engineering for security, and Henning and Garner (1999) consider life cycle models for survivable and secure systems. Non-functional requirements can be classified under three broad categories (Robertson & Robertson, 1999): system-related, process and project-related and humanrelated requirements. The rest of this article is organized as follows. The next section overviews the security goals and requirements. The third section introduces security requirements modeling using the Goal-Oriented Requirements Language (GRL) (ITU, 2002) and UMLsec, a security extension to the Unified Modeling Language (Jurjens, 2005; Elshahry, 2005), and its modifications. The fourth section provides some examples of using GRL and UMLsec models for requirements specifications. We conclude in the final section and provide items for further investigation.

Abstract – Currently, the procedure for admitting new students at SMK Al-Halim Garut is considered less effective and efficient. Since the acceptance of new students is by means of prospective students who must fill out a form using the google forms provided by the school. This makes it difficult to share information with outsiders. After that, prospective students or parents must come to school to just see announcements or information and even submit documents related to the implementation of new student admissions. Therefore, it is necessary to develop a new web-based student information system at SMK Al-Halim Garut which can solve the problems so far. This development stage used the System Development Life Cycle (SDLC) method with the waterfall model and the need for a Unified Modeling Language (UML) which functions to make it easier to describe the system already made. The results showed that the Web-based Information System for New Student Admissions with PHP and SQL was able to manage the implementation of the New Student Admissions, such as registration, selection, announcement, and re-registration. In the feasibility test using a black box, it showed that this software was very feasible in terms of functionality.Keywords : information system, acceptance of new students, System Development Life Cycle (SDLC), Unified Modeling Language (UML).Abstrak - Saat ini prosedur penerimaan peserta didik baru di SMK Al-Halim Garut dinilai kurang efektif dan efisian. Karena penerimaan peserta didik baru dengan cara calon siswa harus mengisi lembaran formulir menggunakan google form yang sudah disediakan oleh pihak sekolah. Hal ini mengakibatkan sulitnya berbagi informasi dengan pihak luar. Setelah itu calon siswa ataupun orang tua siswa harus bersusah payah mendatangi sekolah untuk sekedar melihat pengumuman atau informasi dan bahkan mnyerahkan dokumen persyaratan yang berkaitan dengan pelaksanaan penerimaan peserta didik baru. Oleh sebab itu perlu adanya suatu pengembangan sistem informasi peserta didik baru berbasis web di SMK Al-Halim Garut yang bisa menyelasaikan permasalahan selama ini. Tahap pengembangan ini menggunakan metode System Development Life Cycle (SDLC) dengan model waterfall dan perlu adanya Unified Modeling Language (UML) yang berfungsi untuk mempermudah menggambarkan sistem yang akan dibuat. Hasil penelitian menunjukkan bahwa Sistem Informasi Penerimaan Peserta Didik Baru Berbasis Web dengan PHP dan SQL ini mampu mengelola pelaksanaan Penerimaan Peserta Didik Baru yaitu pendaftaran, seleksi, pengumuman, dan pendaftaran ulang. Pada uji kelayakan yang mengggunakan black box menunjukkan bahwa perangkat lunak ini sangat layak dari aspek fungsional.Kata Kunci : sistem infromasi, penerimaan peserta didik baru, System Development Life Cycle (SDLC), Unified Modeling Language (UML).
