An integration of uml use case diagram and activity diagram with Z language for formalization of library management system

Unified Modeling Language (UML) is the effective standard for modeling object-oriented software systems. However, the ambiguity of semantics and the absence of consistency among UML diagrams lead to lack of precisely defining the requirements of a system. On the other hand, formal methods are techniques and tools use the mathematical notations, and they involve the precise syntax and semantics of the unambiguous software requirements specification. It applied in early stages of Software Development Life Cycle (SDLC). Therefore, an integrated between UML specification and formal specification is required to reduce the requirements' ambiguity and error, and to improve the quality and security of software systems. This paper proposes an approach involves the combining UML use-case diagram and activity diagrams with Z language for formalization of Library Management System (LMS). The focus of this paper is on consistency between the UML diagrams to Z Schema, and then verified by using the Z / EVEs tool.

Framework To Approximate Label Matching For Automatic Assessment Of Use-Case Diagram

E-learning plays a significant role in educating large number of students. In the delivery of e-learning material, automatic e-assessment has been applied only to some extent in the case of free response answers in highly technical diagrams in domains like software engineering, electronics, etc., where there is a great scope of imagination and wide variations in answers. Therefore, the automatic assessment of diagrammatic answers is a challenging task. In this article, algorithms that compute the syntactic and semantic similarities of nodes to fulfill the objective of automatic assessment of use-case diagrams are described. To illustrate the performance of these algorithms, students' use-case diagrams are matched with model use-case diagram. Results from 13,749 labels of 445 student answers based on 14 different scenarios are analyzed to provide quantitative and qualitative feedback. No comparable study has been reported by any other label matching algorithms before in the research literature.

Information system UML-model development by OMG RUP technology for Food industry enterprises

An important element in planning the development of computerized control systems is a systematic study of the subject area. Such modeling used to solve the problem of “software development crisis” - to assess the scale of the system, and the necessary means for its implementation. The paper presents the UML-model of the classes of a food industry enterprise using the example of a bakery. The enterprise actually works by the JIT system way. Therefore, during automation, one must take into account that the main process is strongly associated with the results of auxiliary processes. Based on use-case diagrams, a UML - model of classes for production has been developed. An approach is proposed to solve the problem of designing the structure of an information system based on the UML - classes model of the subject area. The RUP approach to the development of the model of an information system for managing auxiliary business processes of an industrial enterprise was implemented. As a result of the research it was revealed that the data structure will consist of 3 main sections providing information needs of production, management and delivery of finished products to implementation points. The high complexity of the information system’s database is indicated; because of the minimum number of basic classes of domain entities that group tables according to «1- to - n» - connections is not less than 15.

Case Study: Development of the concept of corporate web-site of the bank "Credit Agricole"

Approaches to the development of the concept of a corporate web portal of an international bank are considered. Any company (enterprise) needs information support of its business processes, as well as information interaction in online mode both within the enterprise and with the external environment. With the growing number of employees and sources of corporate information, it becomes increasingly difficult to implement internal communications. There is a need for a single information space and optimization of joint work with information and documents. From this point of view, the portal is one of the powerful tools of business management of the company. The characteristics of the corporate information portal in various aspects of its functioning as a system are described. There are three main functional layers in the typical corporate portal, such as the basic infrastructure layer, responsible for basic services, the layer of application integration, responsible for the interaction of the portal with all existing company applications (DBMS, CRM, ERP, etc.), the layer of interfaces, which includes information content management tools, interfaces for data exchange with information systems of business partners, tools for working with mobile and wireless equipment, etc. Conceptual requirements to the corporate information portal are considered. The analysis of the characteristics of the corporate information portal is carried out. The purpose of the portal is analyzed. Requirements, a diagram of use cases, portal mockups are developed. UML diagrams of use cases are used to describe portal users and the relationships between them. For each use case scenario, it describes its implementation, a brief description, preconditions, the main stream of events, an alternate flow of events, post-conditions. Cross-platform service Figma for designers, which allows several people in real time to work on the same project, is considered.

Software Safety Analysis with UML-Based SRBD and Fuzzy VIKOR- Based FMEA

Software often controls the behavior of mechanical and electrical systems, as well as interactions among their components in cyber-physical systems (CPS). The risks in CPS systems could result in losing tools, features, performance, and even life. Therefore, safety analysis for software in these systems is a highly critical and serious issue. The use of reliability block diagram is a method for checking the safety and reliability of systems. A reliability block diagram is a diagrammatic method for showing how component reliability contributes to the success or failure of a complex system. In this paper, a method for generating RBDs is presented analysis and demonstration of this method capability to evaluation of a software safety by use-case analysis, use-case diagram review, and use-case specification. Then, a Fuzzy VIKOR-based FMEA is used for further evaluation due to the presence of uncertain data. Finally, it is applied to a real CPS.

Improving the identification of functional system requirements when novice analysts create use case diagrams: the benefits of applying conceptual mental models

Planning an information system (IS) is challenging, especially for inexperienced IS analysts, including students. One area that often causes particular difficulty is defining the requirements of the future system—a phase that is crucial to the success of any IS project. While serving as advisers for students carrying out their first IS projects, we observed that “imagining” the future system’s functionality and workflow from the user’s perspective makes it easier for students to identify the system’s functional requirements. This insight led us to suggest refining the requirements phase by structuring the “imagining” process into a formal Conceptual mental model (CMM)—that is, a tangible visual representation of the user’s beliefs and expectations (i.e., the user’s mental model) about the system to be developed. We expect that this approach, taken from the domains of cognitive psychology and human–computer interaction, will improve the ability of inexperienced IS analysts to identify the functional requirements of the future system, along with their associated relations and actors. In particular, we expect that this approach will yield better Use case diagrams (UCDs)—a key component of the Use case model for representing and then specifying system requirements, relations and actors. Here, we report on a controlled experiment testing whether creation of a CMM prior to the creation of a UCD improves the identification of functional system requirements, relations, and actors in terms of correctness, completeness, and irredundancy of the UCD. We found that participants who produced a UCD after producing a CMM performed significantly better in defining system requirements, relations and actors, as expressed in their UCDs, compared to participants who produced a UCD without first producing a CMM. We conclude that our suggested refinement improves the performance of novice IS analysts in capturing, analyzing and defining functional system requirements, relations and actors in a UCD, in terms of correctness, completeness, and irredundancy.

Using the local context for the definition and implementation of visual languages

In general, visual languages need to be simple in order to be easily used and understood. As a result, many of them have simple constructs that can be defined by simply describing local constraints on the constituent elements. Based on this assumption, in a previous research, we developed a local context methodology for the specification of the syntax of simple visual languages such as flowcharts, entity-relationship diagrams, use-case diagrams. In this paper, we extend the methodology by defining a new technique for a local context based semantic translation of a visual language. The technique uses XPath-like expressions, called SGPath, together with a data flow model of execution. As for the case of local syntax checks, attributes and rules to calculate them are defined for each element of the language. For a given element in the abstract sentence graph, the SGPath expressions are used to gather values from its neighbors in order to allow the rules to calculate its semantic attributes. The new methodology has been implemented in the tool LoCoMoTiVe and been tested on visual languages such as entity-relationship diagrams, flowcharts, trees.
