Introduction

Relevant Legislation Data Protection Act 1998 Whenever personal details or other private information is stored about people, it is regulated by the data Protection Act and organisations storing such information must register with the data protection bureau. It gives rights to data subjects (i.e. in this case the patients who have specific data about themselves stored on the health centre system). Data is subject to 8 main regulations to protect the rights and privacy of individuals. These are: 1. Personal data shall be processed fairly and lawfully. 2. Personal data shall be obtained only for one or more specified and lawful purposes. 3. Personal data shall be adequate, relevant and not excessive in relation to the purpose for which it is used. 4. Personal data shall be accurate and, where necessary, kept up to date. 5. Personal data shall not be kept for longer than is necessary for the specified purpose. 6. Personal data shall be processed in accordance with the rights of data subjects under the act (patients have the right to view and correct information held, except in cases of crime or certain government agencies). 7. Data holders should have appropriate measures in place to protect the data against loss, theft or corruption. 8. Personal data shall not be transferred to a country outside the EEC unless that country ensures an adequate level of protection for the rights of data subjects. Computer Misuse Act 1990 This law was introduced to cope with the problems of computer hackers and viruses. The Act was introduced to recognise these three offences: 1. Unauthorised access to computer material If a member of the health centre staff uses another staff members password to log onto their user area, this is illegal. Even if they don't change, delete or damage anything, they are still guilty of accessing materials without authorisation - and this is illegal. 2. Unauthorised access with intent to commit or facilitate a crime The difference between this and the first offence is that the person gaining access to someone else's system is doing so with the sole purpose of doing something illegal e.g. ...read more.

The Hyperlink - when you click your mouse on a navigation hyperlink it will take you to another page. This page could be on the same website or a different website (external link). 2. The Menu System - the navigation menu gives you a choice of which page you want to view next. A menu is a set of hyperlinks grouped together. There are various menu styles such as a side menu which normally sits on the left hand side of the page. 3. Hotspot - this is an area on the web page which when clicked will allow you to jump to another page. It is a way for the designer to make the hyperlink invisible or for them to allow you to click on an image in order to jump somewhere else. When you hover your mouse over a hotspot the cursor changes to a little hand There are a number of ways to create and design a web page: Design Methods Software Advantages Disadvantages Straight from a Microsoft Office application * Word * PowerPoint * Simple, just save as a web page * Can only create a basic page Text Editor * Notepad * Low cost as Notepad is free with windows * You have to know a lot about HTML code * Easy to make a mistake as all the code is written by hand Web Authoring Package * Microsoft Front Page * Macromedia's Dreamweaver * It will provide ready made templates * Easy to add/remove pages without breaking the site navigation * Expensive * Takes time to learn In order for other people to see the health centres web site it must be placed on a web server.

Conclusion

Data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these digits is referred to as a bit (and a string of bits that a computer can address individually as a group is a byte). An example of a digital signal would be the data sent into a television via a digital cable. An analogue sensor can only be On or Off e.g. pressure pad sensor. Computers cannot deal with analogue signals and therefore requires an analogue to digital converter (ADC).This is used to change the analogue data into digital data to allow the computer to process the information The ADC is connected between the sensor and the computers input/output port. Once the computer has processed the data, the output often has to be converted to an analogue signal and so a DAC (Digital to Analogue Converter) is used. Database Systems used in a Health Centre A database is an organised collection of data which is organised into fields and records. The main benefit to the health centre for having a database is that it allows them to search quickly for specific patient information. Databases can be: * Flat-File All data is stored in one large table which can be viewed by opening one data file. It can be created using a database system or a spreadsheet. It is ideal for small amounts of data that needs to be human readable or edited by hand. With this type of system there is unnecessary duplicating of data which can mean that mistakes are more likely to happen during data input. * Relational Data is split up into sensible groups and then stored in separate tables. In the case of the health centre they could have a table with customer data, a table with appointment data etc. All the data is linked together by key fields and a database management system (DBMS). This means that data does not have to be duplicated. Relational databases also have built in functions which allow retrieval, editing and sorting of data to be much quicker. ?? ?? ?? ?? 1 ...read more.
