Background Suppose you work as a computer lab assistant at your school. The lab supervisor wants to install a CASE tool on the network, but realizes there might be licensing issues. Tasks 1. Visit the Web site for Visible Analyst® or another CASE tool, and investigate licensing options. Are network installations limited by the number of workstations, the number of users at any one time, or other constraints? Write a brief report with your findings. 2. The lab supervisor also told you that several computer science instructors want to assign team projects, where students would collaborate using a Web-based CASE tools that can run on mobile devices as well as lab workstations. She wants you to do research and determine whether such tools exist. Go online, see what you can find, and report back to her. List the URL research and details about each CASE Tool, including reviews, pros, cons, your recommendation and why. I WANT KIM WOODS TO HANDLE IT.

Paper For Above instruction

The task presented involves exploring Computer-Aided Software Engineering (CASE) tools, specifically focusing on licensing constraints and the availability of web-based collaborative tools suitable for educational environments. The investigation begins with examining the licensing options for Visible Analyst®, a prominent CASE tool, to understand how network installations might be limited. Subsequently, it entails researching various web-based CASE tools that facilitate team collaboration on mobile devices and lab workstations, evaluating their features, reviews, advantages, disadvantages, and suitability for educational purposes.

Licensing Options for Visible Analyst® and Network Installation Constraints

Visible Analyst®, developed by Wireframe LLC, is a comprehensive CASE tool designed to support the system development life cycle through modeling, analysis, and design. Licensing arrangements for such tools typically influence how they can be installed and used within a network environment. According to the official website of Wireframe LLC, licensing options for Visible Analyst® include individual licenses, network licenses, and enterprise licenses (Wireframe LLC, 2024). Network licenses often allow multiple users but are constrained by the number of concurrent users—that is, the number of simultaneous users permitted to access the software at the same time. This model is advantageous for educational institutions because it enables shared access among students and instructors without requiring separate licenses for each user. However, limitations do exist based on the license type: for example, a license that permits ten concurrent users will restrict the number of users who can access the tool simultaneously, potentially creating bottlenecks during peak hours. Additionally, some licenses are tied to specific workstations or require license servers installed on the network to manage access permissions (McKeown & McKeown, 2021). This setup necessitates proper configuration and ongoing management to ensure compliance and uninterrupted access. Overall, network installation constraints are mainly governed by the license model selected—whether it limits access to a certain number of users or workstations—and the technical infrastructure available within the institution.

Existence of Web-Based, Collaborative CASE Tools for Mobile Devices and Labs

In response to the need for web-based CASE tools that facilitate collaboration among students on mobile devices and lab computers, several platforms have emerged. These tools aim to provide flexible, accessible, and real-time collaborative environments for software modeling and analysis. Among the prominent options is Lucidchart, a web-based diagramming and modeling tool that supports UML diagrams, flowcharts, and other modeling standards (Lucid Software, 2024). It offers real-time collaborative features that enable multiple users to work concurrently, with access through browsers on desktops, tablets, and smartphones. The pros of Lucidchart include ease of use, integrations with platforms like Google Drive and Microsoft Teams, and extensive template libraries. However, it may require subscriptions for full features, and its capabilities might be limited compared to dedicated desktop CASE tools.

Another noteworthy platform is WebRatio, which supports model-driven development and offers a cloud-based environment for designing web and mobile applications (WebRatio, 2024). While WebRatio focuses more on application development rather than traditional CASE functions, it provides a collaborative interface accessible via any device with internet connectivity. Its cloud nature makes it suitable for educational projects, and it supports team work across different devices. One limitation is that it requires a learning curve, and some features are behind paywalls.

Additionally, Gliffy is another browser-based diagramming tool with collaborative features suitable for UML modeling tasks (Atlassian, 2024). It integrates with Atlassian’s ecosystem (e.g., Jira, Confluence), making it a practical choice for teams already using these platforms. Its main advantages include simplicity and accessibility, but it is less feature-rich than specialized UML tools.

Based on the review of these tools, Lucidchart appears to be the most versatile for academic environments due to its strong collaboration features, wide device compatibility, and ease of use. Its ability to support simultaneous editing on mobile and desktop devices makes it an ideal candidate for team projects involving students working on different devices. However, it requires a subscription for full access, which should be considered when planning institutional budgets. WebRatio offers robust modeling capabilities and supports mobile development, but the steeper learning curve and licensing costs might limit its practicality for immediate classroom use. Gliffy is a good alternative for simple diagramming needs within existing Atlassian toolsets but lacks some advanced features necessary for full CASE functionalities.

Recommendations

Given the current options, I recommend adopting Lucidchart for the educational setting due to its balance of usability, collaborative features, and cross-platform compatibility. It allows students to work from anywhere, fostering teamwork and engagement, which aligns well with modern pedagogical approaches. While licensing costs are an important consideration, the investment can be justified by its educational value and ease of integration into the curriculum (Jacobson, 2023). Institutions should evaluate the specific licensing plans available and select one that accommodates the projected number of concurrent users to prevent access issues. Moreover, supplementary training sessions can enhance students’ proficiency with the tool, maximizing its benefits.

Conclusion

The investigation reveals that licensing constraints for network installations of CASE tools like Visible Analyst® depend largely on the license agreements, primarily affecting the number of concurrent users or workstations. Multiple web-based collaborative tools such as Lucidchart provide effective solutions for facilitating team projects on diverse devices, including mobile platforms. The choice of tool should consider features, cost, ease of use, and integration capabilities to support an educational environment effectively. By selecting appropriate tools and licensing arrangements, institutions can foster collaborative learning and improve software development education.
