the database and 
sort 
records 
into numerical or alphabetical order very quickly. Modern databases are relational –
that is, they are made up of related files: customers and orders, vendors and purchases, 
students and tutors, etc. Two database files can be related as long as they have a 


11 
common field. A file of students, for 
example, could include a field called 
Tutor ID
and another file with details 
of the tutors could include the same 
field. This key field can be used to 
relate the two files. Databases like 
Oracle, DB2 and MySQL can manage 
these relationships. 
A database 
query
function allows you 
to extract information according to 
certain conditions or criteria. For 
example, if a managing director 
wanted to know all the customers that 
spend more than Е 8,000 per month, 
the program would search on the name 
field 
and 
the 
money 
field 
simultaneously. 
The best database packages also include 
network 
facilities, which can make 
businesses more productive. For example, managers of different departments can 
have direct access to a common database. Most aspects of the program can be 
protected by user-defined passwords and other
