SQL (often pronounced "sequel") stands for Structured Query
Language, it was developed by IBM in the mid 70's to query databases.
In general, to use the Loadman Fleet Manager, one will not need to be
familar with SQL. But some advanced operations may require a little
understanding of where clauses.
A where clause describes what data will be accessed. An example is
Region='downtown' could be used to select all Services assigned to
that Region.
