Data protection is one of the most serious issues with compute utilizing, particularly for pull offing system. In Hong Kong, information protection is covered by “ Personal Data ( Privacy ) Regulation ” , legislated by “ Privacy Commissioner for Personal Data ” every bit known as ( PCPD ) .The section ‘s mission is to lift up the consciousness of public informations usage from private or public organisations. Some private/public organisation may obtain user ‘s data/info when client did enrollment. Unfortunate, there are many dishonest organisation are utilizing illegal method to gain money from user ‘s informations. For illustration, “ On July 15, 2010, the issuer of Octopus cards in Hong Kong admitted it made $ 44 million dollars in the past half decennary by selling informations from its card holders to a 3rd party spouses. “ ( Canape , 2010 ) This is illegal to sell user ‘s informations to a 3rd party and the award for this is holding a great clip in the gaol. Although it is of import to aware of ethical issues ( The usage of personal informations ) , to avoid hacker ‘s bargains public informations is besides an of import occupation. Personal Data Privacy Ordinance besides protects the public by puting up hash punishments.

State how these would use to the computing machine system being developed. [ 4 Markss ]

Since the information protection jurisprudence in Hong Kong had been set up to warn these dishonest behaviours by organisations, still it is non easy to maintain secure in presents. Heavy penalty must be set to endanger the stealers from stealing. There are a assortment of offenses for disputing the Torahs: “ Non-compliance with an enforcement notice served by Privacy Commissioner carries a punishment of a all right at Level 5 ( At present $ HKG 50,000 ) and imprisonment for 2 old ages. An Individual who suffers harm, including injured feeling, by ground of a dispute of the Ordinance in relation to his or her personal information may seek compensation from the informations user concerned. “ ( PCPD, 2001 )

Under these sorts of strong Torahs and penalty, organisation that obtains public user ‘s informations or a new system which freshly developed will experience safe and comfort.

degree Celsiuss ) Recommend methods that should be utilized to guarantee that informations protection best pattern is implemented in the new system. [ 4 Markss ]

Although Torahs can protect the system from the exterior, the system itself should besides be well-protect by an highly strong plan. One of the best ways to guarantee the protection of a new system is to put in a information protection director. Microsoft System Centre Data Protection Manager ( every bit known as DPM ) is a good pick. Microsoft DPM non merely manages in Window environment, but besides can pull off in SQL, SharePoint, Dynamic AX, Essential Business Server, Window Server and Small Business Server. ( If the new system or database is created by one of the above, felicitation! ) Data Protection Manager back up informations by continuously protecting changed files at the byte-level to a secondary disc, which can be back up to tape. This besides enables rapid and dependable recovery from accessing disc alternatively of waiting to turn up and mount tapes. ( A engineering called ‘Shadow Copy ‘ is used for uninterrupted backups ) . There are so many types of information protection plan to protect your system or database excessively, but this is non over yet. Strong Firewall is needed to support hacker ‘s onslaught to the new system.

With three beds of protections ( Laws, Program back up, Firewall ) , the system should be safe and well-protected.

Describe in item how the system will publish tickets and reference labels based upon client demands.

Explain how the system will cover with the undermentioned issues:

A· Producing tickets that is non easy to hammer or copy. ( 5 Markss )

By the progress of engineering, it is much easier to hammer papers, ticket and even passport. For a big cooperation such as Steam Railway Company, to forestall forge ticket is one of the subject precedences on the on the job list. By the yesteryear, tickets are used to be unprotected ; the lone manner to place is to utilize the oculus and by touch the texture. Nowadays, many companies are utilizing barcode or french friess to forestall ticket forge. The ticket from Steam Railway Company will utilize an beforehand barcode plan called “ Ticket Creator 5.1 ” .This plan provide a alone 10-digit figure on each ticket. ( Depends on the client ‘s volume, figure can be expand to a larger degree ) Barcode ticket can non be forged and copied because each barcode can be merely be used one time to come in. Our Staff can easy place the ticket by utilizing Barcode scanner on the train. Besides, each station will put in entryway machine which available to scan barcode before client come ining the platform. On the other manus, french friess are besides really good to forestall forge but the cost is manner excessively high, so this will non be include in the ticket sale system

Allow clients to choose multiple tickets of different types. ( 5 Markss )

The best manner for clients to choose multiple tickets of different types is to enlarge the ticket sale procedure from the system. When clients request for tickets, the Staff will enter the ticket item and publish it out.

The thing which is needed to make is to let multiple tickets detail input to the system database and multiple ticket printing in one clip. Different type of ticket had already been applied by the system because staff can type in the type of ticket which client wants into the system. If clients are still unhappy to the manner of Steam Railway Company selling method, a hi-tech ticket machines can besides be topographic point at each station.

Research hardware and print media available for publishing labels and tickets for the railroad. State which hardware and media you recommend and quote monetary values for these based upon hardware purchase and annually usage of consumables in the printing procedure. ( 5 Markss )

To forestall forge ticket from the stealers, particularly a Railway Company which uses immense sum of tickets, a high category pressman is need to protect company ‘s prosperity. Datamax is a well-known cooperation which sells high category pressman. Their merchandise is specially designed for printing labels, ticket stuffs and tickets.

Let ‘s look into out the award for the merchandise. The freshly Datamax S-Class Ticket Printer cost around $ HKG 9,000 per each and the plan of Ticket Creator 5.1 cost $ HKG 3,700 with their endeavor barcode version. If each terminus topographic points at least 10 Ticket Printer at the counter for the ticket gross revenues staff, it will be around $ HKG100,000 per station.

Describe how the object-oriented attack to the design of the system in undertakings 1 – 3 differs from utilizing a structured methodological analysis. Explain the advantages and disadvantages of both the object-oriented and structured attacks utilizing the system you have designed to exemplify this.

When object-oriented attack to the designing of system, object-oriented method obtain more information and is more detail so structured methodological analysis. In other word, ‘friendliness ‘ . Object-oriented obtain a functional, structural and behavioural method. It have attribute that describe more information about the object and have behaviours that specify for available usage. Object-oriented have better build-in characteristics in each linguistic communication. Comparing to structured methodological analysis, larger information item will be stored but harder the occupation and structural format. Let ‘s take a expression at structured methodological analysis. It is a quality, structured, well-organize and user-friendly faculty. It has a quality systems, good communicating, organized undertaking direction and good certification etc. The disadvantage of construction methodological analysis would be losing little dealing item. It is excessively general and do non cover every little portion of the system. By utilizing Task 1-3 as a comparing for object-oriented and structured methodological analysis, the large difference will be shown. Object-oriented can divide as functional, structural and behavioural. Each Style have different diagram to utilize, such as activity diagram, category diagram, sequence diagram etc. These diagrams can breakdown general processing into even smaller portion. For illustration, in category diagram, each facet shows the informations have to be type in and which type of input system allow to input. Unfortunate, structured methodological analysis do non like to breakdown so deep, which cut down the informational sum of this method and something will be losing when user notice. In the other word, if the system required a big environment and database, object-oriented will suit for larger system ; if the system is for little utilizations or a little company, structured methodological analysis will be their best pick to take.
