Error Handling In An Activity Diagram ✓ Solved

Error Handling in an Activity Diagram

Refer to the activity diagram Figure 2-15 on page 59 of the textbook. The diagram omits several error-handling pathways. Write a two to three (2-3) page paper in which you: Using Microsoft Visio or an open source alternative such as Dia, update the diagram to include two (2) error-handling pathways. Produce a narrative which describes the added error-handling pathways that includes: an overview of the errors being checked, an explanation of the main reasons why checking for such errors is important, and an overview of other possible errors. Use at least three (3) quality resources outside of the suggested resources in this assignment.

Your assignment must follow these formatting requirements: Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Include a cover page containing the title of the assignment, your name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length. Include charts or diagrams created in Visio or an open source alternative such as Dia. The completed diagrams/charts must be imported into the Word document before the paper is submitted.

Introduction

Error handling is a critical aspect of system design, particularly in software development and process mapping. An activity diagram provides a clear representation of the workflow and serves as a visual tool for identifying paths through a process, including potential error pathways. This paper illustrates how to enhance the existing activity diagram with two error-handling pathways, along with a narrative explaining the rationale behind these additions. The discussion will focus on the types of errors being checked, the significance of error checking in systems design, and an overview of other possible errors.

Updating the Activity Diagram

For the purpose of this assignment, a modified activity diagram will be created to incorporate two error-handling pathways. The two pathways will address user input errors and system connectivity issues. These error scenarios were selected due to their common occurrence in both business processes and software applications. The updated diagram will visually represent these pathways, ensuring clarity in potential error management solutions.

Overview of Errors Being Checked

The first error-handling pathway will focus on user input errors, which occur whenever a user enters invalid data into the system. This could include incorrect data types, missing required fields, or input data that falls outside of pre-defined acceptable ranges. For instance, if a numerical field requires only positive integers and a user attempts to enter negative values or text characters, the system must react appropriately by prompting the user to correct their input.

The second pathway will target system connectivity issues, which may arise when the application is unable to connect to necessary data sources due to network failures or server downtime. In such cases, the system should notify the user of the connectivity issue and recommend remedial actions, such as checking their internet connection or retrying the operation after some time.

Importance of Error Checking

Implementing error-handling pathways is crucial for various reasons. Firstly, it ensures the integrity and reliability of the system. By validating user inputs and monitoring system connectivity, developers can minimize the risks of system crashes, erroneous data processing, and overall user frustration (Sommerville, 2011). When error handling is effectively integrated into the system, organizations can maintain a high level of service quality and user satisfaction.

Furthermore, error checking enhances the user experience by providing clear feedback and guidance on how to correct mistakes. Users are likely to appreciate systems that help them avoid errors and clearly communicate what actions are necessary to resolve any issues (Shneiderman & Plaisant, 2010). This fosters a sense of control and empowerment among users, making them more likely to engage with the system positively.

Overview of Other Possible Errors

In addition to user input errors and system connectivity issues, several other potential errors can arise within an activity diagram context. These might include permission errors, where users attempt to access restricted functionality without appropriate credentials, or transaction failures caused by server overloads during peak usage times. Furthermore, data inconsistencies, whether stemming from integration issues among different systems or inaccuracies within the original data source, can lead to significant challenges in systems operation (Pressman, 2014).

Moreover, consideration should be given to environmental factors impacting system performance, such as hardware malfunctions or software bugs that may result in unexpected behaviors. Each of these issues requires a tailored error-handling strategy to ensure seamless operations and effective incident resolution.

Conclusion

This paper outlines the importance of integrating robust error-handling pathways into activity diagrams to enhance system reliability and user experience. By incorporating user input and connectivity error pathways in the updated diagram, we can address critical areas that lead to erroneous operations. Understanding and planning for potential errors ultimately contributes to the design of more robust and user-friendly systems, reinforcing the need for thorough requirements determination and effective systems analysis.
