Software Requirements Specification (SRS) for Gold Loan Calculator
Introduction
Purpose:
The purpose of this document is to define the requirements for the development of a Gold Loan Calculator. This web-based application aims to estimate the loan amount and interest for gold loans based on the value of the gold pledged.
Scope:
The Gold Loan Calculator will provide users with an interface to input details such as the weight and purity of the pledged gold. The application will calculate and display the estimated loan amount and interest based on the provided information.
System Overview
System Description:
The system will be a client-server application. Users will access the Gold Loan Calculator through a web browser. The server will handle the logic for loan amount and interest calculations.
System Architecture:
The application will follow a three-tier architecture: presentation layer (client-side browser), application layer (server-side processing), and data layer (storage and retrieval of data).
Functional Requirements
Use Cases:
Estimate Gold Loan Details:
- Users can input details such as the weight and purity of the pledged gold.
- The system will calculate and display the estimated loan amount and interest based on the provided information.
- Users can customize purity levels and tenure to get more accurate loan estimates.
Functional Requirements:
Input:
The system shall allow users to enter the following details:
- Weight of Pledged Gold (in grams)
- Purity of Pledged Gold (in carats or percentage)
- Loan Tenure (in months)
Calculation:
- The system shall calculate the estimated loan amount and interest based on standard parameters and user-input details.
Output:
- The system shall display the calculated loan amount and interest to the user.
External Interface Requirements
User Interfaces:
- The user interface shall consist of input fields for the weight and purity of the pledged gold, along with a dropdown menu or input field for loan tenure, and a “Calculate” button.
- The calculated loan amount and interest shall be displayed prominently.
Hardware Interfaces:
- The system should be compatible with standard computing hardware.
Software Interfaces:
- The application will be developed using HTML, CSS, and JavaScript for the frontend.
- The backend can be implemented using a server-side framework (e.g., Node.js, Django) with a database for data storage.
Communication Interfaces:
- The application will communicate with the server for loan amount and interest calculations.
Performance Requirements
Response Time:
The system should provide a response time of under 3 seconds for a typical user input.
Throughput:
The application should handle at least 50 simultaneous users.
System Constraints
Regulatory Requirements:
The application should comply with relevant financial regulations for gold loans.
Hardware Limitations:
The system should be compatible with devices supporting standard web browsers.
Security Requirements
Authentication:
User authentication may be implemented to personalize loan amount and interest estimates.
Data Protection:
User data, if stored, should be securely protected.
Quality Attributes
Reliability:
The application should provide accurate loan amount and interest estimates based on the entered details.
Maintainability:
The code should be well-documented for ease of maintenance.
Usability:
The user interface should be intuitive, requiring minimal guidance.
Testing Requirements
Test Cases:
Test cases should cover various scenarios with different weights, purities, and tenures to ensure accurate loan amount and interest estimates.
Test Case 1:
- Inputs: Weight of Pledged Gold = 20 grams, Purity of Pledged Gold = 22 carats, Loan Tenure = 12 months.
- Expected Output: Estimated Loan Amount ≈ 1,20,000 INR, Estimated Interest ≈ 6,000 INR.
Test Case 2:
- Inputs: Weight of Pledged Gold = 30 grams, Purity of Pledged Gold = 18 carats, Loan Tenure = 24 months.
- Expected Output: Estimated Loan Amount ≈ 1,50,000 INR, Estimated Interest ≈ 9,000 INR.
Test Case 3:
- Inputs: Weight of Pledged Gold = 15 grams, Purity of Pledged Gold = 24 carats, Loan Tenure = 18 months.
- Expected Output: Estimated Loan Amount ≈ 90,000 INR, Estimated Interest ≈ 4,500 INR.
Acceptance Criteria:
The application is considered successful if it produces correct loan amount and interest estimates based on the provided details.
