( a ) DRAFT SCREEN DESIGN

( degree Celsius ) Validation RULES

Make a comprehensive, professional criterion study ( 3 Markss ) depicting in item your system design for the bed engagement system ( 3 Markss ) . This should include the item of Tasks 1-5 plus a treatment of the privacy/security issues associating to the pickings and recording of client payments during the engagement procedure ( 6 Markss ) . You should besides include a treatment of any premises and picks you have made during procedure ( 3 Markss ) plus a reappraisal of your work including any failing and suggested betterment ( 5 Markss ) .

SYSTEM DESIGN FOR BED BOOKING SYSTEM

The NHA is presently running 40 inns and want centralized reserve system and payment system. To look into that the centralised system of the new IT system demand to hold all the information of the 40 shelters. The new system should enter all information inn, room type and room information in a information file or shop informations in one topographic point. Due to the centralised system, the client asks about the Lodge in the modesty in the chief office of free beds. There are excessively many shelters to verify that the petition for which inn room rate is free. So in the new system hunt procedure should be done in existent clip the location, figure of darks and the day of the month. On the other manus, for the engagement procedure, the system needs to enter all the booking information for 40 shelters in a file, reserve. In the reserve procedure, the system needs to enter information about reserves, as the invitee name, room type, room information, get downing day of the month, no of darks and client information such as client name, client figure and so on. Due to the centralised system, the system needs to enter detailed information about the inn engagement and besides send an electronic mail to the inn where the client associated with full payment. If the client is new, the system needs to make the client record. In the system of payment, the client will pay at least 2 times and the enrollment system is the first series with the payment sum and the client makes the 2nd set, the system will read out the payment signifier easy and accurately.

DETAILS OF TASK 1- 5 ANDSECURITY ISSUE

This paper discusses the design of a new computerized system for the National Association of shelters. The NHA wants to centralise its ain processing. So first, we need to make the context diagram to cognize about the NSA new computing machine system and cognize the extent you have to make computing machine maps. Then we have to specify what the system wants to alter the new computerized system and make up one’s mind what to take part in the new system. After making this, we design diagrams DFD know when and who will transport out the associated procedure and make up one’s mind if the information is being stored. When we know where to hive away the informations, these informations shops must be connected together to execute the procedure as accurately specify the relationship between them through the ERD diagram. And decide primary key and foreign key for each tabular array in order to link to each other. Then ELH diagram design for bed reserve for when the rule of modesty, operation and when you ‘re done. To cross-check we besides make the criterion for the new system and make up one’s mind which Fieldss should be involved and specify the name of the tabular array. When the cross-check is All right, we designed the informations lexicon for all elements in the design of databases to hive away and pull off information needed to back up an information system. Finally, we produce a paradigm of new system of national wellness histories and to specify the proof regulations for the system to guarantee that the system will be complete and right information, which are indispensable for the system.

Premise

To alter the computing machine system, it is assumed that all information inn is centrally stored in the office and the information shelter. type of room, briefing room. When the client petitions for hunt, the office of hunts utilizing these stored records. In add-on, the office besides takes the information from clients of all inns and give ID to ease the hunt. We assume that each client record to win at least one reserve. For payment, the payment is supposed to hold at least twice, the first sedimentation and full install and the office will let more than two times. And one time the client makes in installments, the office records the payment in the signifier of payment. Furthermore, the client does non necessitate to cognize your payment ID or ID faux pas, but merely needs to cognize the engagement figure when you own the 2nd series. We assume that there will be new client reserve system and no new inn engagement system. New inn will non be in the enrollment procedure inn.

REVIEW OF WORK

Looking through the general allotment, we designed the system to the CNS hostelling association. There may be some failing and some good points in this allotment theoretical account I ‘ve done. First, the system records all the information shelter and to bespeak free hunt of the bed, we designed the system to happen the bed free of automatically based on standards that we have. When the client makes the reserve, the system will enter client information, booking information wholly. And users can book with many shelters at a clip. During the check-out procedure procedure, let the user to pay at least two installments. For the design of the system to enter the payment information on the peculiar file. To direct electronic mail to shelters spouses, the system will make full the information associated with reading the associated files. For the coverage procedure, the design of the system to inform the procedure.

WEAKNESS AND IMPROVEMENTS

To pattern hostelling system NHA, there is failing and betterment in our system. The failing is that the system does non expose the information secretary of modesty records the engagement procedure. So if something is a job with the engagement procedure, all jobs will be taken by the manager of the modesty of the cardinal office. Therefore we suggest that all reserve clerk shall guarantee that records the right information of engagement and payment. And the new system is a computing machine, so there may be some onslaught on the computing machine as a virus or lost informations. Therefore we suggest that all records must be backed up day-to-day and salvage on other agencies of backup such as Cadmium.
