The analysis and interpretation of Public Service data from secondary sources


A database is just another name for a large collection of information held on a computer in such a way that it can be retrieved in response to specific queries.

For example a query addressed to the DVLA database might be, "Give me a list of all the people living in Hereford who are the registered owner of a Ford Fiesta, colour red, registered between 1998 and 2003".

All of the Public Services use databases extensively to store information about people, vehicles, property, crime etc. These will either be designed specifically for a particular task, such as a Crime reporting package or may make use of off the shelf database applications such as Microsoft Access. The data is held in 'fields' such as :-

This allows for searches of the database using the field names, e.g.:

"List Crimes where Offence details = 'Criminal Damage' and Date Committed is 'between 01/03/2004 and 31/03/2004' and location = 'Beta Road'."

Here is an example of a Crime Report that would be found by this query.
