System Requirements Document (SRD) for project-07b4ce75

1. Introduction

This document outlines the system requirements for project-07b4ce75, a basic calculator application. The project is designed to provide users with a simple and intuitive tool for performing foundational arithmetic operations. The requirements have been updated to reflect the acknowledgment of basic foundational functionality as pre-resolved by the API supervisor.

2. System Overview

The goal of project-07b4ce75 is to deliver a lightweight, user-friendly calculator application that supports essential arithmetic operations. The application will cater to users who need a straightforward tool for quick calculations without the complexity of advanced scientific functions. The system will be accessible via a web interface and optimized for both desktop and mobile platforms.

Key features include:

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• A clean and intuitive user interface.
• Responsive design for usability across devices.

Locale-specific considerations for Greece (GR) include:

• Default language: Greek.
• Numeric formatting: Use commas as decimal separators and periods for thousand separators (e.g., 1.000,50).

3. Functional Requirements

The following functional requirements are defined for project-07b4ce75:

• As a User, I should be able to perform addition, subtraction, multiplication, and division.
• As a User, I should see clear error messages for invalid inputs (e.g., division by zero).
• As a User, I should be able to reset the calculator to its default state with a single click.
• As a User, I should see a history of my last five calculations.
• As a User, I should be able to toggle between light and dark mode for the interface.

4. User Personas

4.1 Regular User

• Description: A general user who needs a simple calculator for everyday arithmetic tasks.
• Goals: Perform quick and accurate calculations.
• Pain Points: Overly complex interfaces, lack of clarity in error handling.

4.2 Student

• Description: A student who uses the calculator for basic math homework or studies.
• Goals: Solve arithmetic problems efficiently.
• Pain Points: Difficulty in accessing recent calculations or resetting the calculator.

5. Visuals Colors and Theme

The following unique color palette has been designed for project-07b4ce75:

• Background: #F3F4F6 (Soft Light Gray)
• Surface: #FFFFFF (Pure White)
• Text: #1F2937 (Charcoal Gray)
• Accent: #3B82F6 (Vivid Blue)
• Muted: #9CA3AF (Cool Gray)

This palette ensures a clean, modern, and professional look while maintaining high readability and accessibility.

6. Signature Design Concept

The Signature Design Concept for project-07b4ce75 is a "Dynamic Calculator Interface" that visually transforms based on user interaction.

Key Features:

• Interactive Button Animations: Buttons will "press" with a subtle 3D effect when clicked, giving users tactile feedback.
• Calculation History Carousel: The last five calculations will appear as a horizontal carousel at the bottom of the screen, with smooth scrolling animations.
• Theme Transition Effect: Switching between light and dark mode will trigger a fluid gradient animation that transitions the background and text colors seamlessly.
• Error State Animation: Invalid inputs (e.g., division by zero) will trigger a gentle shake animation of the calculator screen, accompanied by a red highlight around the input field.

This design ensures the calculator feels alive and engaging while maintaining its simplicity.

7. Non-Functional Requirements

• Performance: The application should load within 2 seconds on standard broadband connections.
• Accessibility: The interface must comply with WCAG 2.1 AA standards.
• Localization: The application must support Greek as the default language and numeric formatting conventions.
• Compatibility: The application must function seamlessly on modern browsers (Chrome, Firefox, Safari, Edge) and mobile devices.

8. Tech Stack

The following technologies will be used for project-07b4ce75:

Frontend

• React for Web

Backend

• Python
• FastAPI

Database

• MySQL (with Alembic for migrations)

Local Orchestration

• Docker
• docker-compose

9. Assumptions and Constraints

Assumptions

• Users will primarily access the calculator via modern web browsers.
• The foundational arithmetic operations (addition, subtraction, multiplication, division) are pre-resolved by the API supervisor.

Constraints

• The application must remain lightweight and performant, with a maximum size of 2MB for the frontend assets.
• Only basic arithmetic operations will be supported; no advanced scientific functions will be included.

10. Glossary

• API Supervisor: The system or individual responsible for ensuring the foundational functionality of the calculator is pre-resolved and operational.
• WCAG: Web Content Accessibility Guidelines, a set of standards for ensuring web accessibility.
• Light/Dark Mode: A feature allowing users to switch between a light-themed and dark-themed interface.
• Alembic: A database migration tool for Python.
