Clues
- A serial file order (maybe based on an account number), lot faster to find data (10, 4)
- Can be set up to reject any data that does not conform to specified rules (4, 8, 8)
- Database consisting of one table. Easily be set up (4, 4, 8)
- Hundreds of people could be looking at a database at one time (availability to many). To avoid problems - record locking mechanism, when one user is looking at a record, no one else can change it but they can look at it. Prevents conflicting updates. (11)
- Process of checking that data is true/correct. By human inspection or automated with barcodes, OCR, RFID, Magnetic strips or smart cards (12)
- Stores data in tables. Each table contains data about one entity. A table is called a relation. (10, 8)
- The unnecessary repetition of data. Leads to complex processing problems and is inefficient (4, 10)
- Transaction must take the database from one valid state to another (11)
- User friendly face that users of the database can see (8, 4, 4)
- When data reflects reality - being as it should be/what is expected (4, 9)
