VORTEXserver is both the
virtual database interface that provides access to multiple
data managers, and other translation and communication services,
including VORTEXcli, the call-level interface.
The database
interface, also called VORTEX, is a protocol that defines
the communication modules and message blocks for all VORTEX-connected
components. VORTEXserver lets you access data from any Windows,
Unix, OS/2, or DOS client that is: » Precompiled (C and
COBOL). » Processed through a program interface (Java, JDBC,
ODBC, Perl or the native VORTEXcli). »
Or, in the case of TRIM and
DesignVision applications, communicate straight to the database
protocol. The client application connects to VORTEXserver,
either on the same machine, or on another machine to reach
data anywhere on the network on one ( or more) of a huge
array of relational and object-oriented data managers, as
well as legacy data structures. The server defines requests
in memory and builds a request block.
This ""messaging"" protocol
functions as an envelope with an instruction sheet and all
necessary data in subsequent sheets. All it needs to know
is which module receives the envelope next. That module
is responsible for opening, reading, and following the instructions,
which include information about who next receives the envelope. |
