22. Data about data.






23. This is a property of data which - when satisfied - requires every value of one field (attribute) of a table to exist as a value of another field in another related table.

27. The dominant database model






28. The process of examining and analyzing data with a view to extracting patterns from it. It is usually done on data warehouses

44. A field in a table with unique values that although it is not the primary key - it could have been used as such.






45. No Transitive Dependencies.






46. The set of fields in a table which stores unique values and so any one from the list can be selected to be the primary key.
