VORTEX++ is a thin class library that rests on top of the actual raw
The API has a message-based interface and is machine-independent,
supporting only three basic datatypes: CHAR/BINARY, NUMBER, and DATETIME.
These attributes make the VORTEXcli very efficient at moving data (either
locally, or across a network); however, it can be cumbersome to use.
VORTEX++ smooths the process by providing a few simple classes to
handle all database access. In addition, it provides convenient classes to
handle the basic datatypes, including operator overloading and many
The main VORTEX++ classes are:
|Encapsulates a database connection. Each instance
corresponds to an actual DBMS connection.
|Encapsulates a SQL statement. Each instance corresponds
to a logical VORTEXserver cursor.
|Describes an output column.
|The base class for all VORTEX++ exceptions.
|The base class for all VORTEX++ data objects.
Like all VORTEX program interfaces, VORTEX++ minimizes network traffic
thereby improving performance, with the following advanced features:
Cursor caching --
Client side cursors are automatically cached, reducing
actual interactions between the Java client and the RDBMS server.
Bulk operations --
SELECT, INSERT, UPDATE, and DELETE requests operate on multiple
records in a single network transaction.
