Data could be any kind of information you want to keep a record of
|
A record holds all of the information about one person, place or object. On a planet database, all of the information about Mars would be held on one record, while all of the information about Venus would be held on another record
|
||||||||||||||||||||||||
A field contains only one piece of information. A record on a planet database might have several fields: size, distance from the sun, time taken to orbit, number of moons, etc
|
A database "query" is a "question" that you ask the database
|
||||||||||||||||||||||||
The database would need an additional field for class (i.e. reptile, mammal, bird, amphibian, fish, etc.) before it could tell you the answer
|
A catalogue is a complete list of items, for example all of the books owned by a library
|
||||||||||||||||||||||||
Besides including information on author, title, genre and number of pages, one of the most important pieces of information is location - this helps you find the book you choose! The database would also be able to tell you if the book was currently available or out on loan
|
A database can be sorted alphabetically or numerically by ascending or descending order
|
||||||||||||||||||||||||
A list of planets could be sorted alphabetically OR by distance from the sun, but not both at the same time (this applies to the time taken to orbit, as well)
|
A database holds ... data!
