Overview
The specifics of the project are divided sections that give the full description of the functions, the objectives, the properties, the requirements and constraints of the project.
Overall description
This section of the SRS describes all the functionalities for the project items. It additionally highlights the information regarding requirements and constraints of the project.
Product perspective
The product perspective for the B&B Online Booking Software System provides an interactive environment via its various interfaces. The system will additionally have a database to aid in better record keeping and management of user information. It would entail:
System Interfaces – No system interface will be needed during the development of this project since the system will be connected with the business’s server.
User Interfaces – This will have the login page and the sign-up interface.
Hardware Interface - There is no hardware interface required for the proposed B&B system
Software interface – The software interfaces required mainly include the viewing applications, that is, web browsers like Firefox Mozilla, Google Chrome and Internet Explorer preferably of the latest version. An Apache HTTP Server, PHP, MySQL and flash player for the graphics acceleration of the web components, will also be mandated for the web application IT project.
Communication Interfaces: The default communication protocol for transmitting data and information would be the TCP/IP for the web server and client facilitated by HTTP at an upper level.
Product functions
1. Logon to the system and logout as well
2. Change the password after logging in the system
3. Able to create new login information
4. Query for vacant spaces two days on advance
5. See current reservations
6. Able to choose a particular
7. An available calendar to help end users select dates
8. Show the pricing strategies set by the admin
9. Admin can use the admin too to customize web operations
User characteristics
Administrator – Has all the administrative privileges to operate on the web system components.
External Users – These are new and prospective clients for the system who need to be signed up.
Customer – They use the B&B system and ought to be computer literate.
Constraints
Some of the constraints include the regulatory policies, the hardware limitations, the parallel operations, safety or security, the control and audit functions for the IS.
Assumptions and dependencies
The user ought to have the ability to use the internet and have constant access to it when they want to use the system.
The TCP/IP protocol has to be installed on the system on which the system runs.
Additionally, the PC has to have the updated versions of the Windows, Mac or Linux operating systems in order to appropriately load and run the system components.
Functional Requirements
The functional requirements for the proposed system define the fundamental and basic components that contain all the necessary information for the successful software requirements specification. This information would enable the final booking system to function consistently.

Functional and non-functional requirements in Software development

...Functional and non-functional Requirements Development of quality and satisfactory software projects is always the maingoal of any software development team. In other words, software developers have to implement a number of strategic techniques necessary for developing a system that satisfies the targeted functionalities. Some of the most crucial factors to be put into close consideration in the development of a system are the functional and non-functional requirements (Aggarwal, 2005). In simple terms, functional requirements entail a set of features or characteristics that define how a particular system is supposed to operate and...

...of software development life cycle, and this is considered as the limitation of the proposed model (Pandey et al., 2010). The proposed model of Nuseibeh (2001) is based upon the concept of Twin Peaks Model (TPM). According to this model, requirement specification and design part of the system are handled in the same time, which result into attaining the perfect system requirements. The equal focus is given to both types of the system. The model accepts changes that emerge from the system at any stage. For this reason, it is useful for the handling of requirements management that deals with changes. The Twin Peaks model (TPM) has commonalities with...
