Database

Database

1. A database is where information is stored. This information has to be easy to access, process and retrieve. It also has to be organised.

2. Examples of databases

   • Schools
   • The police department
   • The Library
   • The hospital
   • The dentist

3. Advantages of different types of databases

   • Records all stored in one place
   • Easily located certain items because its all organised
   • Better security so people cannot access confidential information about customers or employees

4. Disadvantages of different types of databases

   • May be more expensive to run rather than other options
   • If there is too much information in the database it can get too much and may start crashing if its digital
   • Once all the information is set up it will be harder to change

5. What schools store about us

   • I thinks schools store information about us like our medical details.
   • They also may store information on our parents if they ever need to get hold of them.
   • how well we behave in school
   • How good your attendance is
   • Our address
   • What lessons we like/dislike
   • our date of birth and all sorts of information that they need.
   • They need to track how your doing in school so they can help you

6. Categorisation of database

   • Paper based
     • A library has one because they need to keep track of all the books they have.
     • Yellow Pages would have one so they can store all the local landline numbers on there.
     • An advantage to paper based databases are that no one would be able to hack into them and they would only be in one place.
     • A disadvantage to paper based databases are that you could only get to them when your in the place that there in but if you had them on a computer you might be able to access them in different places. Another one is that you would only be able to get one physical copy of the data.
   • Electronic
     • The police have a database because of all the criminals they have. e.g. the crimes they've committed
     • The dentist would have one because they need to keep the information about the patients e.g. medical forms and whats wrong with your teeth
     • An advantage of having an electronic database is that you may be able to access it anywhere you have a computer and you would probably have it backed up so if you loose it you can easily get it back.
   • Both
     • Schools use a database to store all the information that they need to have about the students.
     • The hospital would use one to keep track of their patients and how they're doing
     • An advantage of having both is that if you lost the physical copy of the information that you have you can still access a copy from the computer
