Software Requirement Analysis and Specification

Introduction:
- Software Requirements Specification (SRS) is a document that describes the software's functionality
- Purpose: to bridge the communication gap between developers, testers, and clients
Product Perspective:
- The system can manage water supply, attendance, and worker information efficiently
- Objectives: ensure safe and reliable drinking water, promote sustainability, efficiency, and customer satisfaction
User Characteristics:
- Three types of users: Admin, Worker, and User
- Each user has a specific set of features and functionalities
General Constraints:
- All mandatory fields must be filled with proper information
Assumptions and Dependencies:
- Users should have basic computer knowledge
- The system is dependent on internet connection
- Information provided by users is assumed to be genuine### System Requirements
The application must have a relational database.
The application must display error messages to the user when an error is detected.

Safety Requirements

The system is safe to use.
Data is stored in a central database to minimize data loss in case of mishaps.
Forgot password functionality is available to help users reset their passwords.
Authorization checks the permission level of the user accessing the site.
The system is protected by CSRF (Cross Site Request Forgery) middleware to defend against malicious attacks.

Security Requirements

The system is protected by a login system maintained by the admin.
Admin and staff user passwords are converted to unreadable form using the PBKDF2 encryption algorithm.

Software Quality Attributes

Efficiency: The system is built using pre-defined guided processes and data is stored in one central database.
Extensibility: The system supports future modifications without side effects.
Portability: The system can be run on any operating system with the latest version of a browser installed.
Flexibility: The system keeps updating data according to changes that take place.
Reliability: The system's reliability depends on the maintenance of the database.
Usability: The interface is user-friendly and easy to access and understand.

System Analysis and Design

System design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements.
A system is a set of components with clearly defined behavior that interact with each other in a fixed manner to produce some behavior.

Data Flow Diagram

A data flow diagram is a graphical representation of the flow of data through an information system.
It is used to visualize the flow of data through a system and to model the transformations or processes that occur within the system.

Entity-Relationship Diagram

An entity-relationship diagram is a graphical representation of the interrelationships between entities in a database.
Entities are represented by boxes, relationships are represented by diamonds, and attributes are represented by ovals.
An entity is a thing that is recognized as being capable of an independent existence and can be uniquely identified.

Database Design

A database is a collection of related data that can be of any size and complexity.
Database design is done before building the database to meet the needs of end users.
Normalized tables are used to store data in the database.

Normalized Tables

User Register Table: stores information about registered users.
Book Table: stores information about bookings done by users.
Bill Table: stores information related to financial transactions and invoices.
Feedback Table: stores information related to feedback provided by users.
Payment Table: stores information related to financial transactions and payments.
Admin Login Table: stores information related to administrative user accounts.
Workers Table: stores information about the workers or employees.
Attendance Table: stores information related to the attendance of employees.
Assign Table: stores information about assignments or tasks assigned to individuals or teams.
Bill Generation Table: stores information related to the generation and processing of bills or invoices.
Add Capacity Table: stores information about the capacity and availability of water resources.
Add Salary Table: stores information about employee salaries.
Leave Note Table: stores information related to leave requests and corresponding notes.
Worker Login Table: stores information related to worker or employee login activities.

Detailed Design

Detailed design is the second level of the design process.
It specifies how the modules in the system interact with each other and the internal logic of each module.### Detailed Design
Detailed design expands system design and database design to contain a more detailed description of processing logic and data structures.
It provides a complete design for coding.

Structure of the Software Program

The software program consists of three main components: User Module, Admin Module, and Worker Module.

Admin Module

The Admin Module has 15 sub-modules:
- Login
- Location
- Add workers
- Add Details
- View Workers
- View Attendance
- Assign Workers
- View Assign
- View Work
- Bill Generation
- View Bill
- View Payment
- Add Salary
- Add Capacity
- View Leave
- Logout

Worker Module

The Worker Module has 6 sub-modules:
- Login
- Add Attendance
- View Assigned Work
- View Salary
- Leave Note
- Logout

User Module

The User Module has 9 sub-modules:
- Registration
- Login
- View Details
- Booking Water Supply
- Feedback
- View Bill
- Add Payment details
- View Payment Status
- Logout

Coding

The goal of coding is to translate the design into code in a given programming language.
The coding phase affects both testing and maintenance profoundly.

Programming Style

Selecting module and variable names is important for readability.
Single-entry, single-exit constructs should be used.
Information hiding should be supported where possible.
User-defined types should be exploited where applicable.
Nesting should be avoided if possible.
Module size should be carefully examined for cohesion and coupling.
Module interface should be simple and not have more than five parameters.
Program layout should be organized and presented clearly.
Side effects should be avoided where possible.
Robustness is important to handle exceptional conditions.

Admin Login code is a software component designed to authenticate and authorize administrative users to access an application or system with elevated privileges.
