    Basic information on Databases
    Databases
    *A database is an application software that is used to quickly search and retrieve information or data that has been collected and specially organized.
    *A database may be used to keep information about a CD, in a personal computer; so it’d be a small database. A larger database would be used by public, commercial and industrial organizations to maintain their business and services. Databases can also be used to book holidays and airline tickets through to the Police National Computer.
    *Advantages:
    It's a faster method
    It saves paper
    Alternative to always backing up information
    Wide range of designs
    Improved data security
    CRUD (Create Retrieve Update Delete)
    Disadvantages:
    Time-consuming
    Diffiucult to use at first
    It could be deleted/corrupted/stolen

    Intranets and Encryption
    {IntranetsPg170.jpg}
    {IntranetsPg171.JPG}
    1) An intranet is a private network based on internet standards but only available within the business or other organization. It’s different to the internet in the sense that it cannot be accessed by anyone who’s not a part of the business. Also, it’s not directly connected to the internet, however, some intranets allow access. If a school has an intranet, it may use it in the following ways: to upload room changes, examination timetables, sports teams and results, revision guides and homework tasks. These can be shared between teachers and students.
    2) An intranet is only available within a business or an organisation. An extranet allows authorised outsiders to access the extranets.
    3) EDI: (stands for Electronic Data Interchange) allows data to be exchanged and is a special way to transfer business documents, such as orders and invoices.
    e-commerce: it's the term given to the buying and selling of goods and services throught the internet and, particularly, the WWW (World Wide Web).
    encryption: to put data into a special computer code to prevent other people from accessing the specific data.
