the client/server model, the database operates in the server.

in common.

Sort work area
A work area the SymfoWARE/RDB system uses on magnetic disk. The SymfoWARE/RDB system saves data in a
work table when it needs to save an intermediate result while manipulating data. If sorting is required, the
SymfoWARE/RDB system uses sort work. A work table or sort work of up to a specified fixed amount uses virtual
memory. When a work table or sort work exceeds the fixed amount, it uses an area on magnetic disk. This area is
called a sort work area. A shared sort work area is shared by the entire SymfoWARE/RDB system; own sort work
areas are used privately by each application program or command.
