From a technical standpoint,
DBMSs can differ widely. The terms relational, network, flat, and hierarchical
all refer to the way a DBMS organizes information internally. The internal
organization can affect how quickly and flexibly you can extract information.
Requests for information from a database are made in the form of a query, which
is a stylized question. For example, the query
SELECT ALL WHERE NAME = "SMITH" AND AGE > 35
requests all records in which the NAME field is SMITH and the AGE field is
greater than 35. The set of rules for constructing queries is known as a query
language. Different DBMSs support different query languages, although there is a
semi-standardized query language called SQL (structured query language).
Sophisticated languages for managing database systems are called
fourth-generation languages, or 4GLs for short.
The information from a database can be presented in a variety of formats. Most
DBMSs include a report writer program that enables you to output data in the
form of a report. Many DBMSs also include a graphics component that enables you
to output information in the form of graphs and charts.
