Code Review
Code review is often referred to as a peer assessment of code, which helps developers ensure or improve code quality and identify and rectify errors that may have been missed during the initial development stage before integration and deployment. In other words, code reviews are a practice focused on maintaining software quality, wherein one or more individuals or tools methodically inspect and evaluate the program's source code. After a software developer completes coding, they can easily make mistakes. With this in mind, code reviews provide an excellent opportunity to gain a different perspective on the solutions and implementations, helping to identify bugs, logical errors, overlooked edge cases, or other concerns so we can collaboratively resolve them and prevent mistakes.
The goals of this course included an informal code review where I assessed projects from three prior courses to evaluate both the strengths and weaknesses of the code, as well as suggested improvements that encompassed software engineering, data structures and algorithms, and database elements. Through the enhancements I selected, I was able to demonstrate my ability to fulfill all five course outcomes.
2) Design, develop, and deliver professional-quality oral, written, and visual communications that are coherent, technically sound, and appropriately adapted to specific audiences and contexts
3) Design and evaluate computing solutions that solve a given problem using algorithmic principles and computer science practices and standards appropriate to its solution, while managing the trade-offs involved in design choices.
4) Demonstrate an ability to use well-founded and innovative techniques, skills, and tools in computing practices for the purpose of implementing computer solutions that deliver value and accomplish industry-specific goals.
5) Develop a security mindset that anticipates adversarial exploits in software architecture and designs to expose potential vulnerabilities, mitigate design flaws, and ensure privacy and enhanced security of data and resources.
Through its industry-standard icons and symbols, it ensures intuitive usage of the application. In addition to their algorithms and data structure between the different classes and methods, and their layout and source code, it includes design and engineering considerations. A relational database is used to store the data generated, read, updated, and deleted by users of the application. The debugging tools in Android Studio will also enable you to identify and fix errors in your code. Different types of testing (unit, UI, integration) can be used to ensure your app is functional and stable, as well as Git and platforms like GitHub to manage your code, collaborate with others, and track changes.
With the help of a database, the project will make animal information accessible to users. The CRUD process involves creating, reading, updating, and deleting animals in an animal database. In addition to its official Python driver, MongoDB provides PyMongo as well. There are a number of ways to communicate with MongoDB servers using PyMongo. The program allows you to write and delete data, run queries, retrieve retrieval results, access databases, and execute database commands. With the help of an interactive dashboard (buttons, drop-downs), the Outcomes data from the Austin Animal Center was filtered.
The model layer represents the underlying data/database used in development, while the view layer represents the user-facing visual representation. In user interfaces (UIs), users communicate with the requested data. A MongoDB database is used for this project. The view layer uses Dash Plotly, while the controller layer uses Python with Pymongo, relying on Dash Leaflet. In addition to querying, retrieving results, writing and deleting data, and running database commands, this application performs many database operations.
