Answer

Introduction
An Online Accommodation Booking System (OABS) is an electronic structure used to store and recuperate information and lead trades related to the host. At first arranged and worked through transporters, they were later extended to have administrators and motels. Most cabin systems have their own special central reservation structure to encourage reservations all around. This is profitable to a hoster who has a 'one stop shop' for tickets of motels in the chain wherever on the planet. Most establishments that grasp the name of a stamped chain have the upside of filling their rooms from these booking structures [1]. The string may tie up with referral hotels in objectives where they don't have their own one of a kind cabin.

4. Proposal of Prototyping Tool and Specification for Verify the Client’s Requirements of Online Accommodation Booking System
Prototyping Tool
Functional requirement of the proposed system can be listed as following:

1. Tracking record of the customers making purchase with the Coles.
2. Track the personal details of the customers link with the scheme.
3. Compare the Investments being made by each customer on every day and early basis.
4. To identify the individual who made the maximum purchases and identify the three customers who made the most purchases [3]
5. Reset the entire system and tracking on the first day of the year
6. Allow the customers to record and track their scheme points using the FlyBus Card
7. Allow staffs to easily calculate and feed the data to the FlyBus Card without any hesitation

Prototyping tool details used in Online Accommodation Booking System
Capacity and concurrency: the system must be capable of handling multiple computations executions simultaneously in addition to the specific data storage and the availability of the information related to the number of users interacting with the system [1]. there should not be any data transmission quota as the system will be used by the users for one year.

Performance: the performance of the system must be of high quality considering the quantitative metric for this system and the minimum time lag while using the services. there must be selection of the proper technology that can allow the accomplishment of the required operation in much efficient and effective way.

Maintainability: system will be running as long as the scheme will be working, it is necessary that the system operates properly and effectively throughout the lifespan [2]. It also includes improvement and expand of the existing system as per the need.

Reliability: the system must be reliable enough notify and assure that the transactions being made are true and all the operations are being delivered in an effective and efficient way. there must be effective data transmission between the FlyBus card and the database of the Coles.

Usability: the end-users must accept and be satisfied with the type of the services and the operations being delivered using the proposed information system [3]. the system must be easy enough to be operated by the employees and the end users in an easy and effective way.

Requirement Analysis and Validation
Requirement Analysis is the act of gathering the prerequisites of a framework from clients, clients and different partners. Necessity elicitation and investigation is an iterative procedure with persistent criticism from every movement to different exercises. The procedure cycle begins with space comprehension and finishes with necessities checking. The methods utilized for prerequisite elicitation and necessity investigation process:

1. Space Understanding: This expresses the engineers of the Hotel Management System ought to comprehend the area and discover precisely how such frameworks are functioning in different associations with the goal that this framework can be planned in like manner.
2. Necessity Collection: The clients of the HMS are the official, clients, and their prerequisites are to be known to precede the framework configuration process [4].
3. Characterization: This movement takes the unstructured gathering of prerequisites and arranges them into the sensible meeting.
4. Compromise: Since this Hotel Management System is to be utilized by various client gatherings, so the potential clashes of HMS are to be found and settled.
5. Prioritization: This system empowers the HMS planners to orchestrate the necessities as indicated by their needs according to the clients.
6. Prerequisite Checking: The necessities are checked as per what clients truly need from the framework to find if they are finished and reliable.

Requirement Validation Approval watches that the item configuration fulfils or fits the proposed utilization (abnormal state checking); for example, the product meets the client necessity. The way toward assessing programming amid or toward the finish of the improvement procedure to decide if it fulfils determined prerequisites of the client. Necessity Validation is viewed as significant: – It demonstrates to be valuable in diminishing the mistakes in the framework. Blunders in the report will make many issues which will legitimately influence in programming improvement. – The expense of creating a framework contrasts because of client's necessity issue, which is a lot higher than fixing structure or coding mistakes. There are different Requirement Validation methods which are utilized in the record:

1) Requirement surveys: It is a manual procedure for Online Accommodation Booking System which includes numerous perusers for checking the prerequisites of history. The commentators may likewise check for:

• Verification: Is the necessity expressed is testable?
• Comprehensibility: Is the necessity seen appropriately by the clients of the framework?
• Traceability: Is the starting point of the prerequisite unmistakably comprehended?
• Flexibility: Is the necessity adaptable?

2) Prototyping: In this, the framework's executable model is to be shown by the end-clients and clients of the structure. The prototyping procedures include: ? Use of abnormal state dialects

• Application gathering
• Database programming

3) Testing: Requirements ought to in a perfect world be testable. It enables the business to acknowledge and comprehend the dangers of programming usage. It likewise improves the nature of product advancement.

4) Consistency investigation: To check the consistency, the CASE device must be worked to check every one of the prerequisites in this database for the record of all the data.

5) Inspection: This will include the examination of the proposed product with the help of the five senses including “visual, auditory, olfactory, tactile, and taste” [4]; in software testing taste can be referred to the evaluation of the code and the syntax those could restrict the system from accomplishing the necessary deliverables [5].

6) Demonstration: Manipulation in the product as per the needs and requirements of the end consumers will be the major product for assuring that the performance being delivered is as per the expectation of the end consumers and will be allowing the users in enabling the improvement of the information system as it was expected from the end users [6].
